Each day Sheila doubles the number of push-ups she did the day before on the fifth day she does 2•2•2•2•2 an exponent to write the number of push ups nsheila does on the fifth day

Answers

Answer 1

Answer: $2^(5)$
this means 2 x 2 x 2 x 2 x 2
so you put 2 on the bottom and a small 5 in the top right of it to show that you are multiplying the 2, 5 times.

A ball is thrown vertically upward from the ground with an initial velocity of 122 ft/sec. Use the quadratic functionh(t) = -16t2 + 122t +0 to find how long it will take for the ball to reach its maximum height, and then find the
maximum height. Round your answers to the nearest tenth.

Answers

Answer:

232.6 metres after 3.8 seconds.

Step-by-step explanation:

h(t) = -16t² + 122t

a = -16 b = 122 c = 0

Substitute into the quadratic formula

(Ignore the Â)

$x = \frac{-b±\sqrt{b^(2)-4ac}}{2a}$

$x = \frac{-122±\sqrt{122^(2)-4(-16)(0)}}{2(-16)}$

$x = (-122±122)/(-32)$

Split the equation at the ±

$x = (-122+122)/(-32)$ $x = (-122-122)/(-32)$

$x = (0)/(-32)$ $x = (-244)/(-32)$

$x = 0$ $x = (61)/(8)$

The two x-intercepts at 0 and 61/8. The midpoint of the x-intercepts is the axis of symmetry, which is the x-coordinate of the vertex.

Midpoint = [0 + (61/8)] / 2

Midpoint = 61/16 <= This is the time for maximum height

t = 61/16

t = 3.8125 => Round to t = 3.8

To find the maximum height, substitute t=61/16 into the equation

h(t) = -16t² + 122t

h(61/16) = -16(61/16)² + 122(61/16)

h(61/16) = 232.5625 => Round to h = 232.6

Therefore, the ball will reach the maximum height of 232.6 metres after 3.8 seconds.

The sales tax on a piece of furniture that cost $450 was 28.13 what is the percent sales tax

Answers

We could write a percent equation.
What percent of 450 is 28.13?

Cross multiply and we would get 2813 = 450x
Divide 450 on both sides of the equal sign and x = 6.25111111
Round it
Solution: 6.25% tax

Which BEST approximates the area of the geometric figure?A 4 square units
B 7 square units
C 9 square units
D 11 square units

Answers

By decomposing the figure in simpler ones, we conclude that its area is 9 square units.

How to get the area of the figure?

Let's read the figure from the top.

First, we can see in the top two triangles that have an area of half a square unit, then adding these two we have one square unit.

Below that, there are 4 square units inside the figure.

On the left and right sides, there are triangles of base of 1 unit and height of 2 units, then each of these triangles has an area of:

a = 1*2/2 = 1 square unit

And we have 2 of these triangles, so the total area is 2 square units.

Finally, on the bottom we can see 4 triangles like in the top part, we know that each one of these measure 0.5 square units, then the 4 add up to 2 square units.

Adding all the areas above, we see that the total area is:

A = (1 + 4 + 2 + 2) square units = 9 square units.

So the correct option is C
