What number does the calculator display represent?

Answer:

15

Step-by-step explanation:

I'm assuming that b3 is the variable b times 3. So if you plug in 5 for the b variable you'd get (5)3 which is 5 times 3, or 15.

Answer:

x(-8)

Step-by-step explanation:

Answer:

[tex] \huge \boxed{x = 8}[/tex]

Step-by-step explanation:

f(x) = 70 + 11x

To find the value of x when f(x) =158 , equate f(x) to 158

We have

[tex]70 + 11x = 158 \\ 11x = 158 - 70 \\ 11x = 88[/tex]

Divide both sides by 11

[tex] \frac{11x}{11} = \frac{88}{11} \\ [/tex]

We have the final answer as

Answer:

1. x = 5

Remember that all angles add up to 180, and because you know that one of the angles = 90, you can add the other two angles like so.

6x + 15 + 10x - 5 = 90

2.

Angle 1 = 43 degrees

Angle 3 = 32 degrees

The last one the answer is ( number ) 40 degrees

The line PS can be represented by the other names will be PQ, RQ, RS, PR, RS, and PS. Then the correct option is D.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things. In daily speech, a line segment with two points designating its endpoints is also referred to as a line.

The line is shown below.

Answer:

[tex]y=\frac{1}{2}(x+6)^2-1[/tex]

Step-by-step explanation:

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

[tex]y=a(x-h)^2+k[/tex]

Where (h, k) is the vertex of the parabola that graphically represents the function, and a is a coefficient different from zero.

The vertex of the required equation is located at (-6,-1)

The parabola passes through (-12,17)

Substituting the coordinates of the vertex, the equation of the function is:

[tex]y=a(x+6)^2-1[/tex]

The value of a will be determined by using the given point:

[tex]17=a(-12+6)^2-1[/tex]

Operating:

[tex]17=a(36)-1[/tex]

[tex]36a=18\Rightarrow a=18/36=1/2[/tex]

Solving:

[tex]a=1/2[/tex]

The equation of the parabola is:

[tex]\boxed{y=\frac{1}{2}(x+6)^2-1}[/tex]

Answer:

(-1.6)(3 + 0.1)

Step-by-step explanation:

Sidney applied the steps to find the product of two numbers (3.1) and (-1.6),

Step 1,

(3.1)(-1.6) = (-1.6)(3.1)

Step 2,

(-1.6)(3.1) = (-1.6)(3 + 0.1)

Step 3,

(-1.6)(3 + 0.1) = -4.8 + (-0.16) [Distributive property]

Step 4,

-4.8 + (-0.16) = -4.96

Therefore, expression that correctly fits in step 2 will be,

(-1.6)(3 + 0.1)

Answer:

Step-by-step explanation:

sorry is im wrong

EDIT

on edge im right!!!!!!!!!!!!!!

Work Shown:

f(x) = 4x^(-2) + (1/4)x^2 + 4

f ' (x) = 4*(-2)x^(-3) + (1/4)*2x .... power rule

f ' (x) = -8x^(-3) + (1/2)x

f ' (2) = -8(2)^(-3) + (1/2)*(2)

f ' (2) = 0

Finding the derivative, we have that f'(2) = 0, option D.

-----------------------------

[tex](x^n)^{\prime} = nx^{n-1}[/tex]

-----------------------------

The function is:

[tex]f(x) = 4x^{-2} + \frac{x^2}{4} + 4[/tex]

The derivatives are:

[tex](4x^{-2})^{\prime} = -2 \times 4x^{-2 -1} = -8x^{-3}[/tex]

[tex](\frac{x^2}{4})^{\prime} = \frac{2x}{4}[/tex]

[tex](4)^{\prime} = 0[/tex]

Thus, the derivative of the function is:

[tex]f^{\prime}(x) = -8x^{-3} + \frac{2x}{4} = -\frac{8}{x^3} + \frac{2x}{4}[/tex]

At x = 2:

[tex]f^{\prime}(2) = -\frac{8}{2^3} + \frac{2(2)}{4} = -1 + 1 = 0[/tex]

Thus f'(2) = 0, option D.

Answer:

z = 29°

Step-by-step explanation:

We know that the 3 angles in a triangle always add up to 180°.  So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).  

angle A + angle B + angle C = 180°

59° + 92° + z = 180°

151° + z = 180°

Subtract 151° from both sides of the equation

z = 180° -151°

z = 29°

Answer:

I think the candy cost 51 dollars

Jellybeans: 36$

Gummy worms: 15$

36 + 15 = 51

Step-by-step explanation:

Since jeremiah bought 1 pound for 9 dollar you can minus 9 from the equation which is 51 and since each pound of jelly beans were 9 dollars 9 x 4 = 36 and 51 - 36 is 15 so the cost of the gummy worms are 15 so

Hey there!

Fact: Usually whenever you see the “-th” in word-form in mathematics we know the result will have a decimal in it!

Since you have the “-th” in your problem we know it’ll have a decimal

Now let’s start solving!

8 would be in your ONES place

.

7 would be in your TENTHS place

4 would be in your HUNDREDTHS place

Your answer SHOULD look like this: 8.74 ☑️
