Answer:

p(7) = 57

Step-by-step explanation:

Because this is a function, all you have to do is input 7 for x like so:

p(x)=x^2+x+1 --------------->     p(7)=7^2+7+1

                                            so 49 + 8

                                                = 57

vlada-n [284]

Answer:

11/15

Step-by-step explanation:

If 4 out of 15 are Canadian, the ratio of the probability of picking a Canadian is 4/15.  That means that the probability of NOT picking a Canadian is the complement of 4/15 which is 11/15.  Therefore, the probability of not picking a Canadian is the same thing as the probability of picking an American penny which is 11/15.

What is the value of x?<br><br> What is the value of y?
Rudik [331]

Answer:

Y= 20

X= 25

Step-by-step explanation:

The angles of a triangle have to equal 180

So

80+60 = 140

180 - 140 = 40

40/2 = 20

Y = 20

The angles of a linear line split equal 180

So

2y is one side of it which we learned Y = 20 which makes that side 40

To find the other side just guess and check

6(25) = 150

150 - 10 = 140

So the 2y = 40 and the (6x-10) = 140

So yea boom done

Keith_Richards [23]

Answer:

Step-by-step explanation:

f'(x)=-sin x

f'(x)=\frac{cos \frac{\pi }{3} -cos (\frac{-\pi }{3}) }{\frac{\pi }{3} -(\frac{-\pi }{3}) } \\-sin x=\frac{\frac{1}{2} -\frac{1}{2} }{\frac{\pi }{3} +\frac{\pi }{3} } \\sin x=0\\at x=c ,sin c=0,c=0

c=0∈(-π/3,π/3)
