Answer:
Below.
Step-by-step explanation:
F(x) = (x - 20)(x + 20)
f(x) = x^2 - 400 This opens upwards.
If it opens down we have:.
f(x) = -(x - 20)(x + 20)
f(x) = -x^2 + 400.
The following graph describes function 1, and the equation below it describes function 2. Determine which function has a greater maximum value, and provide the ordered pair. Function 1 graph of function f of x equals negative x squared plus 8 multiplied by x minus 15 Function 2 f(x) = −x2 + 4x + 1 Function 1 has the larger maximum at (4, 1). Function 1 has the larger maximum at (1, 4). Function 2 has the larger maximum at (2, 5). Function 2 has the larger maximum at (3, 2).
Answer:
wait can we have the graph
Step-by-step explanation:
Answer:
Function 2 has the larger maximum at (2, 5).

How many more hours did Tom sleep on the night he slept the most than the night he slept the least? HELPPPPPPPPPPPPPPPPPPPPPPPPPP
Answer:
1 1/4 hours
Step-by-step explanation:
1.Tom slept the most on the night he slept 8 2/4 hours.
2.Tom slept the least on the night he slept 7 1/4 hours
3.To determine the difference between the night he slept the most and the night he slept the least, we subtract the two values.
4.The difference between the night Tom slept the most and the night Tom slept the least is 1 1/4
So your answer is 1 1/4 hours! :)

17. What is the area of the shape? *
5 cm
14 cm
4 cm
14 cm
Answer:
106cm²
Method:
Draw a line separating the two rectangles so you have one with 5cm by 10cm and the other 4cm by 14cm.
5cm by 10cm:
area = 5 × 10 = 50cm²
4cm by 14cm:
area = (4 × 10) + (4 × 4) = 56cm²
area all together:
50cm² + 56cm² = 106cm²
Step-by-step explanation:
First we have to divide the figure into 2 rectangles.
Area of rectangle 1= L*B
9*4=36cm2
Area of rectangle 2=L*B
18*5=90cm2
Total area =36+90=126cm2

For the two right triangles above, explain why a/8=x/12 . What trigonometric ratio is also equal to the two given ratios?
Answer:
sin trigonometry ratio
Step-by-step explanation:
Given
See attachment for triangles
Required
Explain why [tex]\frac{a}{8} = \frac{x}{12}[/tex]
From the attached diagram, both triangles are similar triangles because
(1) the second triangle is a dilation of the first triangle by a ratio of 1.5
i.e
[tex]k = \frac{12}{8}[/tex]
[tex]k = 1.5[/tex]
(2) They have angle 30 degrees, and have their right angles located at the same point
In the first triangle, the sine of 30 degrees is represented as:
[tex]sin(30) = \frac{Opp}{Hyp}[/tex]
This gives:
[tex]sin(30) = \frac{a}{8}[/tex]
In the second triangle:
[tex]sin(30) = \frac{Opp}{Hyp}[/tex]
So:
[tex]sin(30) = \frac{x}{12}[/tex]
By comparison:
[tex]sin(30) = sin(3)[/tex]
Hence:
[tex]\frac{a}{8} = \frac{x}{12}[/tex]

What is the volume of a cylinder with a height of 6.8 ft and a base with a radius of 9.4 ft, to the nearest tenth of a cubic foot?
Answer:
1887.6 ft³
Step-by-step explanation:
What is the volume of a cylinder with a height of 6.8 ft and a base with a radius of 9.4 ft, to the nearest tenth of a cubic foot?
The formula for the volume of a cylinder is given as:
πr²h
From the above question,
r = 9.4 ft
h = 6.8 ft
The volume of the cylinder =
π × 9.4² × 6.8
= 1887.61966 ft³
Approximately = 1887.6 ft³
Jesse bought a car for $25,000. The car
depreciates approximately 10% of its value
each year. What will the car be worth in 5
years?
Answer:
Approximately $14,760 to the nearest 10 dollars.
Step-by-step explanation:
After each year passes the car is worth 100-10 = 90% of the previous year.
So the equation is
A = 25000(0.90)^t where A is the value of the car and t = the time in years.
So in 5 years:
A = 25000(0.90)^5
= 14762.25
HELP PLEASEEEE MATH PROBELM!!!!!
Answer:
15
Step-by-step explanation:
I forgot all of my math vocab but basically because the two lines are parallel, those two angles are equal to each other, so 4x-30=2x
subtract 2x from both sides so that 2x-30=0
Now add 30 to both sides
2x=30
divide both sides by two
x=15

Hi there! Your answers are listed below in the explanation.

Step-by-step explanation:
[tex] \large \boxed{ {a}^{2} + {b}^{2} = {c}^{2} }[/tex]
First, find the missing value of hypotenuse by using Pythagorean Theorem which is in the box.
Given where a and b can be either adjacent or opposite and c-term is hypotenuse.
[tex] \large{ {8}^{2} + {15}^{2} = {c}^{2} } \\ 64 +225 = {c}^{2} \\ 289 = {c}^{2} \\ 17 = c[/tex]
Therefore, the hypotenuse is 17. Next, we are going to find a trigonometric ratio.
[tex] \large \boxed{ \mathsf{sin = \frac{opposite}{hypotenuse}}} \\ \large \boxed{ \mathsf{cos = \frac{adjacent}{hypotenuse}}} \\ \large \boxed{ \mathsf{tan = \frac{opposite}{adjacent}}}[/tex]
sin A means that A is our angle. Therefore, we focus on angle A for our calculation. Adjacent for sin A, cos A and tan A are 15. Opposite is 8 and Hypotenuse is 17.
Therefore,
[tex] \large{ \mathsf{sinA = \frac{8}{17}} } \\ \large{ \mathsf{cosA = \frac{15}{17}} } \\ \large{ \mathsf{tanA = \frac{8}{15}} }[/tex]
Next is sinB, cosB and tanB. That means we focus on angle B. Therefore, our adjacent for this would be 8. Opposite would be 15 and hypotenuse is the same which is 17.
[tex] \large{ \mathsf{sinB = \frac{15}{17}}} \\ \large{ \mathsf{cosB = \frac{8}{17}}} \\ \large{ \mathsf{tanB = \frac{15}{8}}}[/tex]
Sina played basketball on a rectangular court that was 74 feet by 42 feet. After the game, she walked across the court diagonally from one corner to the opposite corner. Approximately what distance did Sina walk in feet?
A: 85
B: 116
C: 61
D: 58
Answer:
85 ft
Step-by-step explanation:
Use the Pythagorean theorem to find the length of the diagonal of the rectangle.
c^2 = a^2 + b^2
c^2 = 74^2 + 42^2
c^2 = 5476 + 1764
c^2 = 7240
c = sqrt(7240)
c = 85
Answer: 85 ft
To be labeled as a jumbo egg, the egg is supposed to weigh 2.5 oz. Jandeliz buys a carton of jumbo eggs and measures one of the eggs as 2.4 oz. What is the MEASUREMENT error?
1, 0.96
2. 0.1
3. 0.042
4. 0.04
Answer: 0.04
Step-by-step explanation:
The measurement error is calculated as:
= Error / Ideal value
= (2.5 - 2.4) / 2.5
= 0.1/2.5
= 0.04
Therefore, the correct option is D.

What is continuous compound interest?Interest that compounded continuously to the principal amount. This interest rate provides exponential growth to a period of time.
Formula of continuous compound interest rate;
A = P[tex]e^{rt}[/tex],
where P is the principal amount, r is the interest rate and t is the time period.
Given:
David invested $89,000 in an account paying an interest rate of 3.1% compounded continuously.
Assuming no deposits or withdrawals are made.
P (principal) = $89,000.00
First, convert R as a percent to r as a decimal
r = R/100
r = 3.1/100
r = 0.031 rate per year,
Then solve the equation for A
A = P[tex]e^{rt}[/tex]
A = 89,000.00(2.71828[tex])^{(0.031)(15)}[/tex]
A = $141,689
Therefore, the amount is $141,689.

the perimeter of a rectangle is 32 feet. the length is 3x the width. what is the length? what is the width.
Answer:
The length is 8
The width is 8
Answer:
Step-by-step explanation:
this is about algebra, and my calculus prof. says that all people struggle with algebra, so work on it :D
P = 32 ( the total )
use the formula
P = 2L + 2W
but we are told that L =3W also sooo put that into L
P = 2(3W ) + 2w
32 = 6W + 2W
32 = 8W
4 = W
so width is 4
and length is 12

if f(1)= 4 and f(n) = -3f(n-1) then find the value of f(6)
Answer:
-972
Step-by-step explanation:
if f(1)= 4 and f(n) = -3f(n-1) then find the value of f(6)
If f(1)= 4
f(2) = -3f(2-1)
f(2) = -3f(1)
f(2) = -3(4)
f(2) = -12
f(3) = -3f(3-1)
f(3) = -3f(2)
f(3) = -3(-12)
f(3) = 36
f(4) = -3f(4-1)
f(4) = -3f(3)
f(4) = -3(36)
f(4) = -108
f(5) = -3f(5-1)
f(5) = -3f(4)
f(5) = -3(-108)
f(5) = 324
f(6) = -3f(6-1)
f(6) = -3f(5)
f(6) = -3(324)
f(6) = -972
hence the sixth term of the sequence is -972

Circles C and D overlap. The distance from point C to point D is 7 centimeters. What is the sum of the areas of circle C and circle D? 7Pi units squared 14Pi units squared 49Pi units squared 98Pi units squared
Answer:
98π cm²
Step-by-step explanation:
A circle is a plane figure. A circle is the locus of a point such that its distance from a given point is always constant.
We can see that both circle C and circle D are equal with a radius of 7 cm.
Area of circle C = π* radius² = π * 7² = 49π cm²
Area of circle D = π* radius² = π * 7² = 49π cm²
The sum of the areas of circle C and circle D = Area of circle C + Area of circle D = 49π + 49π = 98π cm²

For the given cost function C ( x ) = 19600 + 500 x + x 2 , First, find the average cost function. Use it to find: a) The production level that will minimize the average cost
Answer:
The answer is "140".
Step-by-step explanation:
Calculating the average cost:
[tex]= \frac{C(x)}{x}\\\\ = \frac{19600+500x+x^2}{x} \\\\ = \frac{19600}{x}+500 +x\\\\[/tex]
To minimize average cost we have to find x for wich A'(x)=0
[tex]A(x) = \frac{19600}{x}+500 +x \\\\A'(x) = -\frac{19600}{x^2}+1 \\\\0= -\frac{19600}{x^2}+1 \\\\\frac{19600}{x^2}=1 \\\\19600=x^2 \\\\x=140[/tex]
