Sandra throws an object straight up into the air with an initial velocity of 38 ft/s from a platform that is 30 ft above the gro
Makovka662 [10]

Answer:

The answer is C.

Step-by-step explanation:

Given formula h(t)=−16t2+v0t+h0 , where v0 is the initial velocity and h0 is the initial height.

In this case, the initial postion is a platform 30ft above ground so h0=+30

The initial velocity is 38 ft/s straight up into the air so v0=+38

h(t)=-16t2+38t+30

When the object hits the ground, h=0.

h=-16t2+38t+30=0

Simplifying 8t2-19t-15=0

(8t+5)(t-3)=0

t=-5/8 or 3

As time cannot be -ve, t=3s. The answer is C.

What type of Symmetry
nikklg [1K]

Answer:

Line Symmetry, Horizontal and Vertical Lines, 90 and 180 degrees

Step-by-step explanation:

It is line symmetry because you can fold the H, and it would overlap perfectly.

Horizontal and vertical lines because if you were to place a line in the middle both horizontally and vertically it would overlap.

90 and 180 degrees because the H would still have have symmetry if you flipped it on its side or upside down.

In one town, 47% of all voters are Democrats. If three
34kurt

Answer:

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the all voters are democrats

The probability that the all voters are democrats

p = 47% =0.47

q = 1-p =1-0.47 = 0.53

<u><em>Step(ii):-</em></u>

Let 'X' be the random variable in binomial distribution

P(X=r) = n_{C_{r} } p^{r} q^{n-r}

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

n=3 and r=3

P(X=3) = 3_{C_{3} } (0.47)^{3} (0.53)^{3-3}

P(X=3) = 1 (0.47)^{3}

P(X=3) = 0.1038

<u>Final answer:-</u>

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

<u></u>

likoan [24]

Answer:

x =5

Step-by-step explanation:

We can use proportions to solve this problem.  Put the side of one triangle over the same side of the other triangle.

x           4

------ = ----------

40           32

Using cross products

32x = 4*40

32x = 160

Divide each side by 32

32x/32 =160/32

x =5
