Answer:

v = -38

Step-by-step explanation:

v/2 + 15 = -4

Subtract 15 from each side

v/2 + 15-15 = -4-15

v/2 = -19

Multiply by 2

v/2 *2 = -19*2

v = -38

Answer:

v = -38

Step-by-step explanation:

v/2 + 15 = -4

Isolate the variable -->

15-15 --> -4-15 --> 0, -19

v/2  = -19

Multiply both sides by 2 to get rid of the /2

-19 x 2 = -38 =>

v = -38

Answer:

∠a= 65°, ∠b= 115°, ∠c= 25°

Step-by-step explanation:

The sum of the angles in a triangle is 180°. This is abbreviated to '∠ sum of ∆'.

∠c +55° +60° +40°= 180° (∠ sum of ∆PQR)

∠c +155°= 180°

∠c= 180° -155°

∠c= 25°

∠a +60° +55°= 180° (∠ sum of ∆PQS)

∠a +115°= 180°

∠a= 180° -115°

∠a= 65°

The sum of the angles on a straight line is 180°. It's abbreviation is 'adj. ∠s on a str. line'.

∠b +∠a= 180° (adj. ∠s on a str. line)

∠b +65°= 180°

∠b= 180° -65°

∠b= 115°

The missing Value, x, that when multiplied by 5/3^4 gives the result of 5^4 is 13125.

The missing value that, when multiplied by 5/3^4, gives the result of 5^4, we can set up the equation:

(5/3^4) * x = 5^4

To solve for x, we can simplify both sides of the equation. First, let's simplify the right side:

5^4 = 5 * 5 * 5 * 5 = 625

Now, let's simplify the left side:

5/3^4 = 5/(3 * 3 * 3 * 3) = 5/81

Now we have:

(5/81) * x = 625

To solve for x, we can multiply both sides of the equation by the reciprocal of 5/81, which is 81/5:

(81/5) * (5/81) * x = (81/5) * 625

On the left side, the fraction (81/5) * (5/81) simplifies to 1, leaving us with:

1 * x = (81/5) * 625

Simplifying the right side:

(81/5) * 625 = 13125

Therefore, the missing value, x, that when multiplied by 5/3^4 gives the result of 5^4 is 13125.

Answer:

Step-by-step explanation:

Good models are expected to reflect the number of books sold between zero and w numbers of weeks where w is defined.

What is a domain?

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

Here, we have

Given: The function f gives the number of copies a book has sold w weeks after it was published. The equation f(w) = 500 * 2^w defines this function.

The following are all domains for which the average rate of change could be a good measure of the number of books sold:

0 ≤ w ≤ 2

0 ≤ w ≤ 7

0 ≤ w ≤ 10

Hence, good models are expected to reflect the number of books sold between zero and w numbers of weeks where w is defined.

We can distribute the outer x to each term inside

x(x-6) = x^2-6x

So the original equation turns into

x^2-6x = 20

Then you could subtract 20 from both sides to get everything to the same side

x^2-6x-20 = 20-20

x^2-6x-20 = 0

This quadratic equation is in the form ax^2+bx+c = 0 with a = 1, b = -6, c = -20.

The presence of the x^2 term, and having it be the largest exponent, is what makes this a quadratic.

Step-by-step explanation:

Just think how many times each two number goes into the first two numbers

The solutions of the system are y = -8 and x = 9.

One or many equations having the same number of unknowns that can be solved simultaneously are called simultaneous equations. And the simultaneous equation is the system of equations.

Given:

A system of equations,

5x + 6y = -3   {Equation 1}

8x + 8y = 8     {Equation 2}.

Multiply 8 into equation 1 and multiply by 5 into equation 2,

and subtract the equation,

we get,

40x + 48y - 40x - 40y = -24 - 40

8y = -64

y = -8 and x = 9

Remark that exponential functions have horizontal asymptotes .

Graph attached

Answer:

\(1/2\)

Step-by-step explanation:

Because they are scaled copies, the ratios of the sides are equal.

Figure A has a base of 6 units by inspection.

Figure B has a base 3 units by inspection.

So, the scale factor from Figure A to Figure B is \(3/6=\boxed{1/2}\) and we're done!

The scale factor from Figure A to Figure B is 1/2

Figure A:

Base = 6 units

Height = 4 units

Figure B:

Base = 3 units

Heights = 2 units

Using Base of the shape:

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape

= 3 units / 6 units

= 1/2

Using Height of the shape:

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape

= 2 units / 4 units

= 1/2

Hence, 1/2 is the scale factor from Figure A to Figure B.

Step-by-step explanation:

a. Isosceles right triangle

a° = 180 - (90 + 20)

a° = 180 - 110 = 70

b. Isosceles acute triangle

a° = 180 - (70+70)

a° = 180 - 140 = 40

c. The three angles inside a triangle always add up to 180°

∠A = 180 - (70 + 60)

∠A = 180 - 130

∠A = 50

so a° = 180 - 50 = 130

d. Isosceles acute triangle

∠A = 180 - (65 + 65)

∠A = 180 - 130

∠A = 50

so a° = 180 - 50 = 130

e. The angles of a rectangle add up to 360°

a° = 360 - (100 + 95 + 70)

a° = 360 - 265

a° = 95

f. The angles of a rectangle add up to 360°

2a° = 360 - (70 + 60)

2a° = 360 - 130

2a° = 230

a° = 115

2.

a. Straight angle is 180°

180 - 141 = 39

so x° = 180 - (39 + 39)

x° = 180 - 78

x° = 102

b. The three angles inside a triangle always add up to 180°

180 - (40 + 60)

180 - 100 = 80

opposite angle

x° = 180 - (80 + 35)

x° = 180 - 115 = 65

c. The angles of a rectangle add up to 360°

(x + 20)° + x° = 360 - (90 + 90)

(x + 20)° + x° = 360 - 180

(x + 20)° + x° = 180

x° = 80
