An object at the top of a building with height 110 feet is thrown upward with an initial speed of 23 ft/s. Find its position z(t

alina1380 [7]

Answer:

Step-by-step explanation:

Given

Height of building is $h=110\ ft$

Initial upward velocity $u=23\ ft/s$

height of object is given by

$z(t)=ut+\frac{1}{2}gt^2$

but building is already at a height of 110 ft so z(t) must be given by

$Z(t)=ut+\frac{1}{2}(-g)t^2+110$

$Z(t)=23\times t-\frac{1}{2}\times 9.8\times t^2$

$Z(t)=-16t^2+23t+110$

Time when it hits is given by when Z(t)=0[/tex]

$-16t^2+23t+110=0$

$t=\frac{-23\pm \sqrt{(23)^2-4\times (-16)\times 110}}{2\times (-16)}$

$t=\frac{-23\pm 87}{-32}$

$t=3.43\ s$

What’s the answer for A B and C?

dimaraw [331]

Answer:

a = 2

b = 3

c = 8

Step-by-step explanation:

First, let us look at the first two (far left) fractions to solve for a.

Since $2^5 = 2^5$ , nothing needs to change in the numerator. 4 = $2^{2}$

a = 2.

Next, we will look at the first and third fractions to solve for b.

$2^5$ = 32

32 / 4 = 8

$2^3$ = 8

b = 3

Lastly, we will solve for c.

All of these fractions simplify to 8 and are equal to each other.

c = 8

What is an equation of the line that is parallel to y=-4x - 5 and passes through the point (-2, 6)?

Alex73 [517]

Answer:

B.) y=-4x-2

Step-by-step explanation:

If the line is parallel, the slope is the same

y = -4x-5 has a slope of -4, so the new line has a slope of -4

We have a slope and a point, so we can use point slope form

y-y1 = m(x-x2)

y-6 = -4(x--2)

y-6 = -4(x+2)

Distribute

y-6 =-4x -8

Add 6 to each side

y-6+6 = -4x-8+6

y = -4x-2

The volume of 10,000drops of a liquid is 10 fluid ounces. what is the volume of 100 drops.

KIM [24]

We can write a proportion for this problem

10,000drops of a liquid is 10 fluid ounces

100 drops of a liquid is x fluid ounces

x=100*10/10000 =1/10 = 0.1 fluid ounces
