Answer:

117, 9

Step-by-step explanation:

given that an object  moves along the​ y-axis (marked in​ feet) so that its position at time x​ (in seconds) is given by

f (x )equals 117 x minus 13 x squared​,

f(x) = 117x-13x^2

a)Instantaneous velocity function

v(x) = f'(x) = 117-26x

b) When x=0 we get

v(0) = 117 feet /sec

c) When v =0 we have

117=13x\\x=9

At 9 seconds  velocity will be 0

Factor 75t2 + 12.<br> 3(5t + 2)2<br> 3(25+2 +4)<br> 3(251-4)
frosja888 [35]

Answer:

75t^2+12=3(25t^2+4)

Option C)

Step-by-step explanation:

Here we are given with the expression 75t^2+12

The GCF of 75t^2 and 12 is 3

Hence we take 3 as GCF and bring it in front of the bracket.

3(25t^2+4)

It can not be factorise furthure  as there is no GCF of 25 and  also there is no rule for sum of squares so that we may apply it on this. Hence the answer would be

3(25t^2+4)

Option C)

A salt modure has 7 parts water and 1 part salt Suppose another part of salt is added What is the new ratio of salt
Sunny_sXe [5.5K]

Answer:

14:2 - 14 parts water and 2 parts salt

Step-by-step explanation:

The original ratio was 7:1. So, that means if you added another part to the salt it would make 2. That means that the 7 parts of water would become 14 parts. Since the ratio of the salt part was doubled from 1 to 2, you would have to do the same with the water ratio part. Hoped this helped!

Explain why this statement is true:<br> 7a +4 – 2a = 7a + (-20)+4
MAVERICK [17]

Answer:

This equation has one solution so given statement is true.

Step-by-step explanation:

7a +4 – 2a = 7a + (-20)+4

5a + 4 = 7a - 16

5a - 7a = -16 - 4

- 2a = - 20

a = 10

This equation has one solution so given statement is true.
