The graph represents a quadratic function. Write an equation of the function in standard form.

Answers

Answer 1

Answer:

Below

Step-by-step explanation:

From the graph, the zeroes are at -4 and - 0.5 so the equation starts like this:

a (x+4)(x+.5) = 0 now ya need to sub in a point to calculate 'a'

...... point 0,4 results in this:

a (0+4)(0+.5) = 4

2a = 4

a = 2

so the equation becomes 2 ( x+4)(x+.5) = 0

2 ( x^2 + 4.5x +2) = 0

2 x^2 + 9x + 4 =0

prism?
a. 5h + 6
b. 5h + 12
c. 10h + 6
d. 10h + 12

Answers

Answer:

5h+6

Step-by-step explanation:

I was litterly just doing this trust me im right lol

Answer:

D. 10h+12

Step-by-step explanation:

You have to multiply to find the area of each rectangle. There are 3 pairs of rectangles that are identical to one another.

2*h = 2h * 2 = 4h

3*h = 3h *2 = 6h

2*3 = 6 *2 = 12

10h+12

Answer = 4.18

Line d has a slope of -8/3. Line e is perpendicular to d. What is the slope of line e?

Answers

Answer:

slope of line e=3/8

Step-by-step explanation:

we are given that line d's slope is -8/3, and we want to find the slope of line e, which is perpendicular to d

perpendicular lines have slopes that are negative and reciprocal; if you multiply the lines together, the result is -1

therefore, to find the slope of line e (m is the slope):

-8/3m=-1

multiply by -3/8

m=3/8

so that means the slope of line e is 3/8

Solve the equation 506x - 92y + 90 = 498 - 4x + 6y

Answers

506 x - 92 y + 90 = 498 - 4 x + 6 y

Geometric figure:

line

y = (255 x)/49 - 204/49

510 x - 98 y - 408 = 0

506 x - 92 y + 90 = 6 (y + 83) - 4 x

Real solution:

y = (255 x)/49 - 204/49

Solution:

y = (255 x)/49 - 204/49

Integer solution:

x = 49 n + 40, y = 255 n + 204, n element Z

Solution for the variable y:

y = 51/49 (5 x - 4)

Answer:

Hi! The answer to your question is [tex]x =\frac{49y}{255} +\frac{4}{5}[/tex]

The required measure of x in the triangle QRS is given as x = 8.

What are Similar triangles?

Similar triangles are triangles that have the same shape but possibly different sizes. More formally, two triangles are similar if their corresponding angles are congruent (equal in measure), and their corresponding sides are in proportion (have the same ratio).

Here,
Since Triangle QRS is similar to triangle QXY.
The property of similar triangle states that the sides of both the triangle will be proportional to each other.
So,
QR/QX = QS/QY

Substitute the value in the above expression,

6/18 = x/ [x + 16]

Simplifying the above expression,
x + 16 = 3x
x = 8

Thus, the required measure of x in the triangle QRS is given as x = 8.

Answers

Answer:

26.25 square feet

Step-by-step explanation:

Calculation to determine the area of the seat

Using this formula

Area=1/2*(b1+b2)*h

Where,

b1=8 feet

b2=7 feet

h=3.5 feet

Let plug in the formula

Area=1/2*(8+7)*3.5

Area=1/2*15*3.5

Area=26.25

Therefore the area of the seat is 26.25 square feet
