Answer:

A, D

Step-by-step explanation:

When solving for x, we want to get all x terms on one side and all non-x terms on the other side. To make it so that x is by itself, we need to get rid of -3. We can do this by adding 3 to both sides, which demonstrates the addition property of equality. This property states that if you add a quantity to one side of an equation, you must add the same quantity to the other side as well.

You recently received your verizon wireless phone bill for the month. The total is $70.52. Included in that total is $13.27 in s

weeeeeb [17]

So 70.52 and 13.27

so 13.27 is what percent of 70.52
percent means parts out of 100

what percent of 70.52
'of' can be tranlated to mutiply
13.27=x% times 70.52
13.27=x/100 times 70.52
13.27=70.52x/100
13.27=0.7052x
divide both side by 0.7052
18.82
the answer is 18.8%

the easy way is

to find percent assume 70.27=100
so x/100=
13.27/70.52 then multiply by 100=0.18817 multipliy 100
18.817=round 18.8%

answer is 18.8%

The function H(t) = −16t2 + 96t + 80 shows the height H(t), in feet, of a projectile after t seconds. A second object moves in t

Oksi-84 [34.3K]

we have that

H(t) = −16t² + 96t + 80
g(t) = 31 + 32.2t

Part A)
see the attached table
the solution to H(t) = g(t) is between t=4 sec and t=5 sec
for t=4 sec
H(4)=208 ft and g(4)=159.8 ft
so
H(t) > g(t)

for t=5 sec
H(5)=160 ft and g(5)=192 ft
so
H(t) < g(t)

that change of H(t) from being greater to becoming smaller tells me that the solution is in that interval [4, 5]

Part B)Explain what the solution from Part A means in the context of the problem
when H(t)=g(t) means that the projectile destroyed the object N 2 in the interval [4,5]

to find the exact solution

−16t² + 96t + 80=31 + 32.2t
−16t² + 96t + 80-31-32.2t=0
−16t² + 63.8t + 49=0

using a graph tool
see the attached figure

the exact solution is
t=4.65 sec
