Answer:

C.)  The ball was thrown from a height of 3 feet

Step-by-step explanation:

In the standard form of a quadratic function, f(x) = ax² + bx + c,

c is the constant term (also known as the y-intercept of the parabola)

In this situation, the ball is thrown up into the air and the flight path will be in the shape of a parabola

The equation y = -16t² + 40t + 3 has a y-intercept of 3, meaning the flight path began at 3 feet above the ground, as you can imagine by looking at the graph of the equation, below.  The y-intercept is at (0,3)

Answer:

i think its c

Step-by-step explanation:

Answer:

The answer is C. 5a² - 4a + 1

First you want to Distribute the Negative Sign:

= 10a² + 3 − 5a + −1 (2 + 5a² − a)

= 10a² + 3 + −5a + (−1) (2) + −1 (5a²) + −1 (−a)

= 10a² + 3 + −5a + −2 + −5a² + a

Add Like Terms:

= 10a² + 3 + −5a + −2 + −5a² + a

= (10a² + −5a²) + (−5a + a )+( 3+ −2)

= 5a² + −4a + 1

Answer:

1.92 yd  x 3.83 yd  x 2.58 yd

Step-by-step explanation:

We have given a rectangular base, that its twice as long as it is wide.

It must hold 19 yd³ of debris.

Lets minimize the surface area, subject to the restriction of volume (19 yd³)

The surface is given by:

[tex]S=2(w*h+w*2w+2wh)=2(3wh+2w^2)[/tex]

The volume restriction is:

[tex]V=w*2w*h=2w^2h=19\\\\h=\frac{9.5}{w^2}[/tex]

replacing h in the surface equation, we have:

[tex]S=2(3wh+2w^2)=6w(\frac{9.5}{w^2})+4w^2=57w^{-1}+4w^2[/tex]

Derivate the above equation and set it to zero

[tex]dS/dw=57(-1)w^{-2} + 8w=0\\\\57w^{-2}=8w\\\\w^3=57/8=7.125\\\\w=\sqrt[3]{7.124} =1.92[/tex]

The height will be:

[tex]h=9.5/w^2=9.5/(1.92^2)=9.5/2.69=2.58[/tex]

Therefore,The dimensions that minimize the surface are:

Wide: 1.92 yd  

Long: 3.83 yd

Height: 2.58 yd

Answer:

B: DCE=D'C'E'

I hoped this helped you!

The required Triangle DCE is congruent to triangle D'C'E'. Option B is correct.

In geometry, two figures are congruent if they have the same shape and size, and all their corresponding parts (sides, angles, and vertices) are congruent. Congruent figures can be moved, rotated, or reflected without changing their shape or size.

Here,
Triangle DCE is congruent to triangle D'C'E'.

This is because a translation is a type of transformation that preserves the shape and size of the original figure, so the two triangles are congruent with each other.

Thus, the required Triangle DCE is congruent to triangle D'C'E'. Option B is correct.

Answer:

number of red tags = 200 - 70 - 38 = 92

Step-by-step explanation:

Jordan has a total of 200 name tag and the tags have different varieties of colors. The tags have blue, yellow and red color . Let us find the number of blue  tags

number of blue tags = 35% of 200

number of blue tags = 35/100 × 200

number of blue tags = 70

The number of yellow tags = 38

The remaining number of tags are red color. Therefore the number of red tag will be the total number of tag minus the number of blue tags and the number of yellow tags.

number of red tags = 200 - 70 - 38 = 92

Answer:

Cost of the tires in 2008 = 23333 dollars

Step-by-step explanation:

Number of snow tires purchased are represented by,

T = [tex]\frac{500(t+20)}{(t+75)}[/tex]

Where t = duration from year 2000

Similarly, cost of the tires area represented by,

C = [tex]\frac{t+75}{1-.05t}[/tex]

Therefore, cost of T tires = C × T

= [tex]\frac{t+75}{1-.05t}[/tex] × [tex]\frac{500(t+20)}{(t+75)}[/tex]

= [tex]\frac{500(t+20)}{1-0.05t}[/tex]

Now cost of the tires in year 2008 (t = 8 years)

Total cost = [tex]\frac{500(8+20)}{(1-0.05\times 8)}[/tex]

                 = [tex]\frac{14000}{0.6}[/tex]            

                 = $23333.3

                 ≈ 23333 dollars

5x+8-7x=-4x+1

Combine like terms

-2x+8 = -4x+1

Add 4x to each side

-2x+4x+8 = -4x+4x+1

2x+8 = 1

Subtract 8 from each side

2x+8-8=1-8

2x = -7

Answer: C I think

Step-by-step explanation:

Answer:

Height of the mountain was 28331.8 feet.

Step-by-step explanation:

An observer took the measurements from two sights C and D.

Point D was 1000 ft away from the earlier sight point C.

Angle of elevations from points C and D were 85° and 83° respectively.

From ΔABC,

tan85 = [tex]\frac{h}{x}[/tex]

x = [tex]\frac{h}{tan85}[/tex] -----(1)

Similarly, from ΔABD,

tan83 = [tex]\frac{h}{(x+1000)}[/tex]

x + 1000 = [tex]\frac{h}{tan83}[/tex]

x = [tex]\frac{h}{tan83}-1000[/tex] -----(2)

Now we substitute the value of x from equation (1) in the equation (2)

[tex]\frac{h}{tan85}=\frac{h}{tan83}-1000[/tex]

0.122785h - 0.087488h = 1000

0.035296h = 1000

h = 28331.822 ft

h ≈ 28331.8 ft

Therefore, height of the mountain was 28331.8 feet.
