Step-by-step explanation:

The vertex of the function f(x) = x²+10 is (0,10). Correct option is (A).

Vertex form of equation is an alternate way of writing the equation of a parabola

The vertex form of an equation is
f(x)= a(x-h)²+k,

Here, h and k are constants

The given equation is,

f(x) = x²+10

To determine the vertex of the equation,

substitute x=0,

f(x)=0+10

f(x)=10

The vertex of the function f(x) is (0,10).

The mean for 2018 scores is:

[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]

[tex]M ean ( \overline X) = \dfrac{74 + 78+79+77+75+73+75+77}{8}[/tex]

[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]

Step-by-step explanation:

N is the number of times per year

Annually would be one time per year so n =1

Answer:

If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved. Also, "t" must be expressed in years, because interest rates are expressed that way.

Simplifying

x = 4.5 + -0.5y

Step-by-step explanation:

The boundary line of the inequality is intersecting the x-axis at 4.5.

The given inequality is 4x + 2y < 18.

A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.

Graph the inequality by finding the boundary line, and then shading the appropriate area.

Now, 4x + 2y < 18 can be written as y<−2x+9.

The boundary line of the inequality is given below.

The boundary line of the inequality is intersecting the x-axis at 4.5.

Ion really get wym by “ what is the face”

Answer:

True: The smaller angle is 36°; The larger angle is 54°

False: The smaller angle is 18°. The larger angle is 72°

If you create an equation using this scenario, it would be (18+x)+x=90, because complementary angles sum up to 90°. Add the like terms to get 18+2x=90. Subtract 18 on both sides to get 72. Divide 2 on both sides to result with x=36. Subtract 90 with 36 to get 54. The smaller angle is 36° and the larger angle is 54°.

Answer:

There are 60 girls and 40 boys in the class.

Step-by-step explanation:

Given that the mean weight of 100 students in a certain class is 71kg, while the mean weight of boys is 65kg and that of girls is 75kg, to determine what is the number of boys and girls the following calculation must be performed:

1 x 75 + 0 x 65 + 75

0.9 x 75 + 0.1 x 65 = 74

0.8 x 75 + 0.2 x 65 = 73

0.7 x 75 + 0.3 x 65 = 72

0.6 x 75 + 0.4 x 65 = 71

Thus, there are 60 girls and 40 boys in the class.

Answer:

y = -2x + 8

Step-by-step explanation:

(−6, 20) and (0, 8)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(8 - 20) / (0 - (-6))

Simplify the parentheses.

= (-12) / (6)

Simplify the fraction.

-12/6

= -2

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = -2x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (0, 8). Plug in the x and y values into the x and y of the standard equation.

8 = -2(0) + b

To find b, multiply the slope and the input of x(0)

8 = 0 + b

b = 8

Plug this into your standard equation.

y = -2x + 8

This is your equation.

Check this by plugging in the other point you have not checked yet (-6, 20).

y = -2x + 8

20 = -2(-6) + 8

20 = 12 + 8

20 = 20

Your equation is correct.

Hope this helps!
