Answer:
3.8
Step-by-step explanation:
We can use sohcahtoa to solve this. First, we know that this triangle is a right triangle, as well as one angle and the opposite side to that angle. We are trying to find the hypotenuse.
Therefore, as sin takes opposite and hypotenuse into account, we can use that to get that sin(41°) = 2.5/x . Multiply both sides by x and divide both sides by sin(41°) to get x = 2.5/sin(41°) =3.8
Question 8 (1 point) A man launches a toy rocket from the roof of a building 72 feet off the ground. The rocket has an initial velocity of 88 feet per second. The height of the ball t seconds after it was thrown into the air can be modeled by the function. h(t) = -16ť +88t + 72 Find the maximum height that the ball reaches during its flight.
Answer:
thanks for the points and sorry i dont under stand
Step-by-step explanation:
find the value of x: then find the measure of each angle
Answer:
Step-by-step explanation:
In a parallelogram, opposite angles are equal.
∠G = ∠E
5x - 9 = 3x + 11
Add 9 to both sides
5x = 3x + 11 + 9
5x = 3x + 20
Subtract 3x from both sides
5x- 3x = 20
2x = 20
Divide both sides by 2
x = 10
∠G = 5x - 9
= 5*10 - 9
= 50 - 9
∠G = 41°
∠G = ∠E = 41°
In parallelogram, adjacent angles are supplementary.
∠G + ∠D = 180
41 + ∠D = 180
∠D = 180 - 41
∠D = 139
∠D = ∠F = 139°
k+1/2 =4 solve for the variable
Answer:
k+1/2 =4
subtract 1/2 from both sides
= k = 3.5 or 3 1/2

Step-by-step explanation:
Which is the graph of the function: f(x) = x2 - 4x + 3
Answer:
Option 1
Step-by-step explanation:
To find the graph of the quadratic function, we find it's zeros.
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
f(x) = x² - 4x + 3
This means that [tex]a = 1, b = -4, c = 3[/tex]
So
[tex]\Delta = b^{2} - 4ac = (-4)^2 - 4(1)(3) = 16 - 12 = 4[/tex]
[tex]x_{1} = \frac{-(-4) + \sqrt{4}}{2} = 3[/tex]
[tex]x_{2} = \frac{-(-4) - \sqrt{4}}{2} = 1[/tex]
Zeros at x = 1 and x = 3, that is, it crosses the x-axis at this values, so the graph is given by option 1.
Gary went to dinner with his friends. The total bill comes to $135.00 before tax. He wants to leave a 15% tip before tax. He also must pay an 8% tax on the bill. How much does Gary spend in total?
No links or I will report!
Answer:
Gary spends a total of $166.05
Step-by-step explanation:
15% tip: would be 15% of 135, so 0.15 times 135, which would be $20.25 for the tip before tax
8% tax: would be 8% of 135, so 0.08 times 135, which would be $10.8
Then we add $20.25+$10.8+$135= $166.05
Hope I helped, please correct me anywhere you think I may have messed up if I did make mistakes.

A certain type of flashlight requires two type-D batteries, and the flashlight will work only if both its batteries have acceptable voltages. Suppose that 90% of all batteries from a certain supplier have acceptable voltages. Among twenty randomly selected flashlights, what is the probability that at least nineteen will work? What assumptions did you make in the course of answering the question posed? a. we have assumed here that the batteries' voltage levels are independent. b. we have assumed here that the batteries' voltage levels are dependent.
Answer:
a) 0.064
b) 0.002
Step-by-step explanation:
a) Assuming that the batteries' voltage levels are independent
Probability = 0.8 * 0.8 = 0.64
b) batteries' voltage levels are dependent
20/19 (0.064)^19 *0.036 + 20/20 (0.064)^20 *0.036^0
= 0.002

Find the equation for the circle with center (-1, - 4) and passing through (-5,5).
Answer:
[tex](x+1)^2+(y+4)^2=97[/tex]
Step-by-step explanation:
Hi there!
Equation of a circle centered at (h,k):
[tex](x-h)^2+(y-k)^2=r^2[/tex] where r is the radius
1) Plug in the center
[tex](x-(-1))^2+(y-(-4))^2=r^2\\(x+1)^2+(y+4)^2=r^2[/tex]
2) Plug in the given point and solve for r²
[tex](x+1)^2+(y+4)^2=r^2[/tex]
Plug in (-5,5)
[tex](-5+1)^2+(5+4)^2=r^2\\(-4)^2+(9)^2=r^2\\16+81=r^2\\r^2=97[/tex]
3) Plug r² back into the equation
[tex](x+1)^2+(y+4)^2=r^2\\(x+1)^2+(y+4)^2=97[/tex]
I hope this helps!
Gopal gave away 25% of his stamps and had 450 stamps left. How
many stamps did he give away?
Answer:
150 stamps
Step-by-step explanation:
100% - 25% = 75%
[tex]\frac{y}{450} :\frac{25}{75}[/tex]
y × 75 = 25 × 450
75y = 11250
75y ÷ 75 = 11250 ÷ 75
y = 150

5. Sara thinks the following expressions are equivalent:
2x + 3 = x/2 + 3/4
Is she right? If so, prove that these two expressions are equivalent. If not, what error(s) did she make?
[tex]\sf\purple{No, \:Sara\: is \:wrong.}[/tex]
[tex]2x + 3≠ \frac{x}{2} + \frac{3}{4} [/tex]
[tex]\sf\red{Here's\:why:}[/tex]
[tex]L. H. S. = 2x + 3[/tex]
[tex]R. H. S = \frac{x}{2} + \frac{3}{4} \\ = \frac{x \times 2}{2 \times 2} + \frac{ 3}{4} \\ = \frac{2x + 3}{4} [/tex]
Clearly,
[tex]2x + 3≠ \frac{2x + 3}{4} \\✒ \: L.H.S.\:≠\:R. H. S. [/tex]
[tex]\boxed{Therefore,\:the\:two\:expressions \:are\:not\:equivalent.}[/tex]
To make them equivalent, Sara can simply divide L. H. S. by 4.
By doing so, she'll have
[tex] \frac{2x + 3}{4} = \frac{2x + 3}{4} \\ ๛L.H.S.=R. H. S[/tex]

The mean daily production of a herd of cows is assumed to be normally distributed with a mean of 36 liters, and standard deviation of 7 liters.
A) What is the probability that daily production is less than 23.4 liters? Use technology (not tables) to get your probability.
Answer=
(Round your answer to 4 decimal places.)
B) What is the probability that daily production is more than 45.7 liters? Use technology (not tables) to get your probability.
Answer=
(Round your answer to 4 decimal places.)
Answer:
A) 0.0359
B) 0.0829
Step-by-step explanation:
A) Using normalcdf on your calculator, or using something online, you can plug (-1000, 23.4, 36, 7) to represent the lower bound, upper bound, mean, and standard deviation respectively. The probability that daily production is less than 23.4 liters is 0.0359
B) Similarly, we can plug (45.7, 1000, 36, 7) in as the upper bound is infinity, and the lower bound if 45.7. Our answer is then 0.0829
A Fulcrum of a Pyramid is 6cm Square at the
top and 12cm square at the bottom and is loem highe
Calculate the volume of the fulcrum.
Answer:
288 cubic cm
Step-by-step explanation:
Volume of the pyramid = 1/3 * base area * height
Base area = 12 * 12
Base area - 144 sq. cm
Height = 6cm
Volume of the pyramid = 144 * 6/3
Volume of the pyramid = 144 * 2
Volume of the pyramid = 288 cubic cm

IT
Answer:
44.402
Step-by-step explanation:
Equation
SA = 2L*W + 2L*H + 2*WH
Givens
L = 2.7
W=1.13
H = 5
Solution
LW = 2.7 * 1.13 = 3.051
LH = 2.7 * 5 = 13.5
WH = 1.13 * 5 = 5.65
SA = 2*3.051 + 2*13.5 + 2*5.65
SA = 6.102 + 27 + 11.3
SA = 44.402

Answer:
The possible solutions are -4 and -12
Step-by-step explanation:
(C+8)^2=16
Take the square root of each side
sqrt((C+8)^2)=sqrt(16)
C+8 = ±4
C+8 = 4 C+8 = -4
Subtract 8 from each side
C+8-8 = 4-8 C+8-8 = -4-8
C = -4 C = -12
The possible solutions are -4 and -12
