Find S25 for (-7) + (-2) + 3 + 8 +...

1 answer:

3 0

$a_1=-7 \\ a_2=-2 \\ \\ d=a_2-a_1=-2-(-7)=5 \\ \\ \\ S_{25}= \cfrac{2(-7)+(25-1)5}{2}\cdot25 = \cfrac{-14+120}{2}\cdot25 =\cfrac{106}{2}\cdot25 =1325$

Your answer is B. 1325

PLEASE HELP! We can translate ()=2|−2|−5 to the right 3 units and up 5 units to create (). Write the equation for function g.

alisha [4.7K]

Answer:

$g(x)=2\,|x-5|$

Step-by-step explanation:

Recall that a horizontal translation (shift) in 3 units to the right involves directly subtracting 3 from the variable x (horizontal axis variable) , and that moving the function up 5 units involves adding to the whole function 5 units. That is:

$g(x)=2\,|x-3-2|- 5+ 5\\g(x)=2\,|x-5|+0\\g(x)=2\,|x-5|$

The world’s largest round pizza was set in December 2012 by five Italian chefs. The diameter of this pizza was 131 feet. If this

Tems11 [23]

First find the area of the whole pizza.

The formula for area of a circle is Area = PI x r^2

The diameter is given as 131 feet, so r would be 131/2 = 65.5 feet.

I will use 3.14 for PI since the problem doesn't say what value to use.

Area = PI x 65.5^2

Area = 3.14 x 4290.25

Area = 13,471.39 square feet

Divide the total area by the number of pieces:

13,471.39 / 50 = 269.43 square feet

To find the length of the crust first find the circumference of the whole pizza:

Circumference = PI x diameter

Circumference = 3.14 x 131 = 411.34 feet

Now divide the total by the number of pieces:

411.34 / 50 = 8.23 feet

Each slice has an area of about 269.43 square feet and a crust length of 8.23 feet.

Part of the graph of the function f(x) = (x – 1)(x + 7) is shown below.Which statements about the function are true? Select thre

sertanlavr [38]

The statements about the function that are true are

The vertex of the function is at (–3,–16).
The graph is increasing on the interval x > –3.
The graph is positive only on the intervals where x < –7 and where x > 1.

<h3>How to interpret the graph?</h3>

The equation of the graph is given as

f(x) = (x - 1)(x + 7)

The graph of the function is added as an attachment

On the graph, we have

Vertex = (-3, -16)

This is so because the graph has a minimum point of (-3, -16)

Also, the graph crosses the x-axis at x = 1 and x = -7

This means that the graph is positive at x >1 and x >-7

Because the vertex is a minimum, the graph is increasing at the left of its symmetry i.e. x > -3
