Answer:

First equation = 3a + 9

= 3( a+3 )

Second equation = a²- 9

= a² - 3 ^ 2

= (a+3) (a-3)

Hence,

HCF = ( a+ 3)

Hope this helped

All the best !!

Given f"(x) = 2, f'(1)=4, and f(2)=-2,<br> find f(x).
Anna [14]

Answer:

Step-by-step explanation:

f"(x)=2

integrating

f'(x)=2x+c

f'(1)=2+c=4

c=4-2=2

f'(x)=2x+2

integrating

f(x)=2x^2/2+2x+a

f(x)=x^2+2x+a

f(2)=-2

(2)^2+2(2)+a=-2

4+4+a=-2

a=-2-8=-10

f(x)=x^2+2x-10

Sati [7]

Answer: the percent of the students at this university are foreign = 30%

Step-by-step explanation:

Given: Probability that college students are foreign students who also smoke: P(S|F)=0.12

Probability that foreign college students smoke P(S∩F)=0.4

The probability that the students at this university are foreign :

P(F)=\dfrac{P(S\cap F)}{P(S|F)}  [By conditional probability formula]

=\dfrac{0.12}{0.4}\\\\=0.3

Hence, the percent of the students at this university are foreign = 30%
