Bottom left. Because of th eminus sign, the v curve is "upside-down" and because of the +1, its function value peak is at 1

Which choices are common factors of the numerator and denominator of the fraction? 21/28

lesya [120]

They are unlimited.
But you can easily multiply 21*28= 588 to find a common factor.
So 588 is a common factor, but there are more.

A vendor sold 72 hotdogs and hamburgers during a football game if the ratio of hotdogs to hamburgers sold was 8:1 how many of ea

Marysya12 [62]

$\bf \cfrac{hotdogs}{hamburgers}\qquad 8:1\qquad \cfrac{8}{1}\qquad \cfrac{8\cdot \frac{72}{8+1}}{1\cdot \frac{72}{8+1}}\implies \cfrac{8\cdot 8}{1\cdot 8}\implies \cfrac{64}{8}$

If f(x) = 3x + 2 and g(x) = x2 x, find each value. 18. f(2)=

Pavel [41]

F(2) = 8
if x = 2 then you plug in 2 for x making the equation 3(2) + 2 which equals 8

What is the recursive formula for this arithmetic sequence 6, -24, 96, -384

Artemon [7]

Answer:

Option A. $a_{1} =6$ $a_{n}= a_{n-1}(-4)$

Step-by-step explanation:

The given sequence in the question is 6,-24,96,-384.......n

and we have to give the recursive formula for this arithmetic sequence.

We can re write the sequence to make it more simpler

6,6(-4),(-24)(-4),(96)(-4).......n terms

Now we can say $a_{1} = 6$

and $a_{n}= a_{n-1}(-4)$

Therefore the recursive formula of the sequence is $a_{1} = 6$

$a_{n}= a_{n-1}(-4)$

4) (Assume AR is tangent) Given: AR 12 SR - 7.7 Find: cs (Round to nearest tenth.)

andreev551 [17]

The length of CS is 11.0

Explanation:

Given that the length of the tangent AR is 12

The length of SR is 7.7

To find: The length of CS

The tangent secant theorem states that "if a tangent and a secant are drawn from an external point to a circle, then the square of the measure of the tangent is equal to the product of the measures of the secant’s external part and the entire secant."

Applying the tangent secant theorem, we have,

$AR^2=SR\times RC$
