Answer: 6 foot
Step-by-step explanation:
You want to use the equation
5(n)
n will be 0.20 since the tree grew by 20% of its original height
5(0.20)=1
Now add 1 with 5
1+5
6
Answer:
6.0 ft
Step-by-step explanation:
20% of 5.0 ft is 1.0 so you add, 1.0ft+5.0ft=6.0ft
Divide 32x3 + 48x2 − 40x by 8x.
4x2 − 6x + 5
4x2 + 6x − 5
4x3 − 6x2 + 5
4x3 + 6x2 − 5
Answer:
4x^2 + 6x - 5.
Step-by-step explanation:
Dividing term by term:
= 4x^2 + 6x - 5.
By Dividing 32x^3 + 48x^2 − 40x by 8x, we get 4x^2 + 6x - 5. Thus, option B is correct.
What is a quadratic equation?
A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
We have to Divide 32x^3 + 48x^2 − 40x by 8x.
32x^3 + 48x^2 − 40x
Take 8x common from each term
8x(4x^2 + 6x − 5)
Dividing term by 8x term:
8x(4x^2 + 6x − 5) / 8x
= 4x^2 + 6x - 5.
Thus, option B is correct.

Answer:
Given function:
g(x) = x² - 6x + ca)
c = 2Th x-intercept found when g(x) = 0
x² - 6x + 2 = 0Solve the equation to find the values of x:
x² - 6x + 2 = 0x² - 6x + 9 = 7(x - 3)² = 7x - 3 = ±√7x = 3 ± √7The x-intercepts are (3 + √7, 0) and (3 - √7, 0)
b)
c = 10Solve as above:
x² - 6x + 10 = 0x² - 6x + 9 + 1 = 0(x - 3)² = -1The left side is a square of a number which is always positive, the right side is negative.
It means there is no solution, so no-x-intercepts.
The graph of the function lies above the x-axis.
Henry's dinner bill is $132 the sales tax of 10% he lives at it of 15% how much will I pay in tax how much does it pay in tip what is his total bill
Answer:
$165
Step-by-step explanation:
Dinner bill = $132
Sales tax = 10% of dinner bill
Tip left = 15% of dinner bill
Amount of sales tax :
10% of $132
0.1 * $132 = $13.2
Amount of tip left :
15% * $132
0.15 * $132 = $19.8
Total bill :
Dinner cost + sales tax + tip
$132 + $13.2 + $19.8
= $165
Neptune's average distance from the Sun is 4.503 × 109 km. Mercury's average distance from the Sun is 5.791 × 107 km. About how many times farther from the Sun is Neptune than Mercury
9514 1404 393
Answer:
Step-by-step explanation:
The ratio of distances is ...
Neptune distance / Mercury distance = (4.503×10^9)/(5.791×10^7)
= 450.3/5.791 = 77.76 . . . . cancelling factors of 10^7
Neptune is about 77.76 times as far from the Sun as Mercury is.
Duncan is running to raise awareness and money for cancer. He finds 2 people who have pledged to
donate money based on the distance he runs. His neighbor says he will donate $0.25 for every 40 feet
Duncan runs. His aunt also says that she will donate $12 for every mile he runs. If Duncan runs a total of
7 miles during the cancer awareness run, how much money will he have raised based on these two
donations?
Answer:
$1008
Step-by-step explanation:
12 x 7 = $84 his aunt gives him.
1 mile = 5,280 feet
5,280 x 7 = 36,960 feet he ran.
5,280 ÷ 40 = 132 for every mile he runs
132 x 7 = $924 from his neighbor.
924 + 84 = 1,008

Mr. Fisherman spent his weekend working in his yard. He had 1/6 of a bag of soil that he spread evenly among his 2 garden beds. How much soil did he put in each garden bed?
Answer:
1/12 per bag
Step-by-step explanation:
A Fisherman spent his weekend working on his farmland
He had 1/6 of a bag of soil
He spreads it evenly among his 2 garden beds
Therefore the soil in each garden bed can be calculated as follows
= 1/6 ÷ 2
= 1/6 × 1/2
= 1/12 per bag

Consider the equation shown.
x – 3 = 2x + 14
What is the solution to the equation?
A. -17
B. -11
C. 11
D. 17
Answer:
A
Step-by-step explanation:
Given
x - 3 = 2x + 14 ( subtract x from both sides )
- 3 = x + 14 ( subtract 14 from both sides )
- 17 = x → A
Answer:
D
Step-by-step explanation:
we collect like terms to remain with
x-2x =14+3
-x =17
divide both sides by -1 to remain with
X = 17

Given:
The height of the swipe card in feet after t seconds is
[tex]h(t)=-3t^2+15t+18[/tex]
To find:
The maximum height of the swipe card and the time at which it reaches this height.
Solution:
We have,
[tex]h(t)=-3t^2+15t+18[/tex]
Here, leading coefficient is -3, which is negative. It means it is a downward parabola and the vertex of the downward parabola is the point of maximum.
If a quadratic function is [tex]f(x)=ax^2+bx+c[/tex], then the vertex is
[tex]Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)[/tex]
In the given function, we get
[tex]a=-3,b=15,c=18[/tex]
Now,
[tex]-\dfrac{b}{2a}=-\dfrac{15}{2(-3)}[/tex]
[tex]-\dfrac{b}{2a}=2.5[/tex]
Putting t=2.5 in the given function, we get
[tex]h(2.5)=-3(2.5)^2+15(2.5)+18[/tex]
[tex]h(2.5)=36.75[/tex]
So, the vertex of the given parabola is at (2.5,36.75).
Therefore, the maximum height of the swipe card is 36.75 feet and it reaches this height after 2.5 seconds.
Leilani hung a triangular pennant for her favorite baseball team in her room as shown below.
If the area of Leilani’s pennant is 82.65 in.2, what is the measure of the base in inches?
Answer:
Step-by-step explanation:
recall the area of a triangle is Area = 1/2* Base* height
then we know the height, and the area solve for the base
I'll do the algebra symbolically so you can see how
A = 1/2 *B * H ( start here)
2A/H = B ( move to here )
Now plug in what you know on the left side
2*82.65/17.4 = base
9.5 = base :)

C. y= (1)/(2)x - 1
D. y = 2x – 1
what is the value of z?
Answer:
3 (z = 35)
Step-by-step explanation:
(22 + 19) + 104 + z = 180° => triangle sum theorem
41 + 104 + z = 180
145 + z = 180
145 + z - 145 = 180 - 145
z = 35

Next let's find the area of the circle with the gray area. We would have:
[tex]\pi r^2=\pi50^2=\pi2500[/tex]
Now we subtract and get:

What is the sum of angles of quadrilateral?The sum of the angles of the quadrilateral is 360 degrees.
We need to find the ∠BCA:
∠OBD = 90
∠OAD = 90
So angles in quadrilateral BOAD
56, 90, 90 and∠ BOA
56 + 90 + 90 + ∠BOA = 360
∠BOA = 360 - 90 -90 - 56
∠BOA = 124
∠BCA is angle at circumference
∠BOA = 124, is the angle at centre
Angle at Centre = 2 x Angle at circumference
Angle at Circumference = Angle at Centre / 2 = 124/2 = 62
∠BCA = 62 degrees
thus, Option B. is correct.
