[tex]x_{v}[/tex]Answer:

The vertex of an up - down facing parabola of the formy = ax" + bx + c is xy =

The parabola params are:

a = 8, b = -14, c =3

[tex]x_{v}=b/2a[/tex]

[tex]x_{v}[/tex]=-(-14)/2·8

simplify

[tex]x_{v}[/tex]=-(-14)/2·8

[tex]x_{v} = 7/8[/tex]

Plug in [tex]x_{v}[/tex]=7/8to find the [tex]y_{v}[/tex] value

[tex]y_{v}[/tex]= -25/8

Therefore the parabola vertex is

(7/8 , -25/8)

If a < 0, then the vertex is a maximum value

If a > 0, then the vertex is a minimum value

a = 8

Minimum(7/8 , -25/8)

Answer:

A is the answer

Step-by-step explanation:

Answer and Step-by-step explanation:

A is the answer because

you need to look at how many of each number and see how many of that number is given. Then, see which graph has the same amount of that number.

We can see that the first answer choice (A) has all the same number of the numbers from the list of numbers given to us.

Answer:

WXV=87° because they are opposite angle

Step-by-step explanation:

frist we need to find TU

TU=1/2×87°

TU=43.5

WSTU is half circle =180°

WS+ST+TU=180°

72°+43.5+ST=180°

115.5+ST=180°

ST=180°-115.5

ST=64.5°

the measurement of UV=wu-x

UV=180°-87°

UV=93° the inner angle that made by UV

the arc of UV1/2=93° cross production

UV=46.5

Answer:

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Step-by-step explanation:

You know the with and the length and height of all of them so just do math :)

Surface area is 300 in Squared

Step-by-step explanation:

2(lw + wh + hl) = rectangular Prism Formula

Length- 12

Width- 9

Height- 2

So just Substitute the values.

2( 12 x 9+ 9 x2 + 12 x 2) = ?

2(108 +18+ 24)

2 x 150

= 300

The equation can be used to calculate the output values in the table is y = 2x.

A equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

The equation can be used to calculate the output values in the table is determined in the following equation.

The equation is;

y = 2x

When the value of y = 4 the value of x is;

y = 2x

4 = 2x

x = 4/2

x = 2

When the value of y = 6 the value of x is;

y = 2x

6 = 2x

x = 6/2

x = 3

When the value of y = 8 the value of x is;

y = 2x

8 = 2x

x = 8/2

x =4

When the value of y = 10 the value of x is;

y = 2x

10 = 2x

x = 10/2

x = 5

Hence, the equation can be used to calculate the output values in the table is y = 2x.

Answer:

triangle and trapezoid

Step-by-step explanation:

The correct answer is Option B) Rectangle

A solid  bounded by plane faces of which one, called the base, is a polygon and the other faces are all triangles meeting at a point outside the polygon.

Given here that the base of the pyramid is a rectangle and thus the plane slicing through the vertex along the perpendicular distance will result in two congruent rectangles at the base as the vertex projects on the midpoint of a rectangle.

Hence, the correct option is B)

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Answer:

THE ANSWER IS A. They have different y-intercepts but the same end behavior.

I used Desmos to graph the function g(x)=4(1/4)^x+2

They have different y-intercepts because function f(x) is 4, while the y-intercept on graph is 6

But they have the same end behavior at 2.

Answer:

y = -2x + 5 [ 1st option ]

Step-by-step explanation:

Consider any two points , say

Firstly let's find the slope of the line as ,

=> m = y₁ - y₂ / x₁ - x₂

=> m = 3-1 / 1-2

=> m = 2/-1

=> m = -2

Third point is, (3 , -1) . Using slope point form .

=> y - y₁ = m ( x - x₁ )

=> y - (-1) = -2( x - 3)

=> y + 1 = -2x +6

=> y +2x +1-6=0

=> y +2x -5 = 0

=> y = -2x + 5

On looking at options first one is correct

Answer:

Question 2: x<-2

Question 6: 1.75 + 0.65m ≤ 10

Question 3: x ≥ -40

Question 4: Graph B

Step-by-step explanation:

Question 2:

since it needs to be greater than 11, we should add a number greater than 4 to seven. so it would be x>2. but since we are subtracting, we turn the 2 negative and flip the sign. Now it would be x<-2

Question 6:

the flat fee is 1.75 and they pay an additional 0.65 for every mile.

We know that the price has to be either less than or equal to 10. And the symbol is ≤. The inequality is 1.75 + 0.65m ≤ 10

Question 3 :

subtract 3 from both sides:

x/4 + 3 - 3 ≥-7 - 3

x/4≥-10

multiply each side by 4

x/4 * 4 ≥ -10 * 4

x ≥ -40

Question 4:

-3x-5 < -2

add 5 to both sides

-3x -5 + 5 < -2 + 5

-3x < 3

divide by -3

-3x / 3 < 3/3

x>-1

D. 5

Step-by-step explanation:

We can triangle JHK is isosceles because two of its sides are radii, and radii of the same circle are always equal. Let the radius equal r. We can say that both JH and HK equal r because the extend from the center to the circle. We can set up the equation:

PJHK = JK + JH + HK

18 = 8 + r + r

10 = 2r

r = 5

Since HK equals r, it equals 5.
