Step-by-step explanation:

Base on the question where as asking to state the translation vectors could have been used for the pair of figures, base on my research, I would say that the answer would be arrow pointing to the right.

Answer:

Brandon

Step-by-step explanation:

GIVEN: Branden and Pete each play running back. Branden carries the ball $75$ times for $550$ yards, and Pete has $42$ carries for $380$ yards.

TO FIND: Who runs farther per carry.

SOLUTION:

Total yards traveled by Brandon $=550\text{yards}$

No. of times ball carried by Brandon $=75\text{ times}$

Average yards per carry for Brandon $=\frac{\text{total yards traveled}}{\text{number of times ball carried}}$

$=\frac{550}{75}$

$=\frac{22}{3}\text{ yards per carry}$

$=7.33\text{ yards per carry}$

Total yards traveled by Pete $=380\text{ yards}$

No. of times ball carried by Pete $=42\text{ times}$

Average yards per carry for Pete $=\frac{\text{total yards traveled}}{\text{number of times ball carried}}$

$=\frac{380}{42}$

≅ $9\text{ yards per carry}$

As the number of yards per carry is higher for Brandon , therefore he runs farther per carry.

Which function in vertex form is equivalent to f(x) = x2 + x +1? f(x) = (x + one-quarter) squared + three-quarters f(x) = (x + o

a_sh-v [17]

The function in vertex form is $f(x)=(x+\frac{1}{2})^{2}+\frac{3}{4}$ ⇒ 3rd answer

Step-by-step explanation:

The vertex form of the quadratic function f(x) = ax² + bx + c is

f(x) = a(x - h)² + k, where

a is the coefficient of x²
(h , k) are the coordinates of the vertex point
$h=\frac{-b}{2a}$ , wher b is the coefficient of x
k = f(h), that means value f(x) when x = h

∵ f(x) = x² + x + 1

∴ a = 1 , b = 1

∵ $h=\frac{-b}{2a}$

- Substitute the values of a and b to find h

∴ $h=\frac{-1}{2(1)}$

∴ $h=\frac{-1}{2}$

Substitute the value of x in f(x) by the value of h to find k

∵ f( $\frac{-1}{2}$ ) = $(\frac{-1}{2})^{2}+\frac{-1}{2}+1$

∴ f( $\frac{-1}{2}$ ) = $\frac{1}{4}-\frac{1}{2}+1$

∴ f( $\frac{-1}{2}$ ) = $\frac{3}{4}$

- k is the value of f(x) when x = h

∵ h = $\frac{-1}{2}$

∴ k = f( $\frac{-1}{2}$ )

∴ k = $\frac{3}{4}$

Substitute the values of a, h and k in the vertex form

∵ f(x) = a(x - h)² + k

∵ a = 1 , $h=\frac{-1}{2}$ , $k=\frac{3}{4}$

∴ $f(x)=1(x-\frac{-1}{2})^{2}+\frac{3}{4}$

∴ $f(x)=(x+\frac{1}{2})^{2}+\frac{3}{4}$

The function in vertex form is $f(x)=(x+\frac{1}{2})^{2}+\frac{3}{4}$

Need help on this, I never learned how to do this yet and it’s on homework

Wewaii [24]

For a function f(x), its average rate of change on an interval [a, b] is given by what's called the "difference quotient",

$\dfrac{f(b)-f(a)}{b-a}$

and is basically the ratio of the difference in values of f(x) at the endpoints to the difference in the endpoints themselves.

I assume the 6 intervals below each table correspond to each table immediately above them.

From the first table, we get the following average rates of change (after arranging the intervals from left to right):

• [-3, -2] : (f(-2) - f(-3)) / (-2 - (-3)) = (7 - 12)/1 = -5

• [-2, -1] : (f(-1) - f(-2)) / (-1 - (-2)) = (4 - 7)/1 = -3

• [-1, 0] : (f(0) - f(-1)) / (0 - (-1)) = (3 - 4)/1 = -1

• [0, 1] : (f(1) - f(0)) / (1 - 0) = (4 - 3)/1 = 1

• [1, 2] : (f(2) - f(1)) / (2 - 1) = (7 - 4)/1 = 3

• [2, 3] : (f(3) - f(2)) / (3 - 2) = (12 - 7)/1 = 5

Just do the same for the other two tables. Note that each listed interval has length 1, so practically, each average rate of change over [a, b] is exactly f(b) - f(a).

For parts (c) and (d):

• (c) You'll notice that each of the average rates of change are odd numbers …

• (d) … but they're not necessarily all the same size, and they follow slightly different patterns.

Answer:

when we put an exponent on a number which already has an exponent, the exponents are multiplied
