Answer:

a.) 94 cm^2

Step-by-step explanation:

3 x 4 = 12

5 x 3 = 15

4 x 5 = 20

12 + 12 + 15 + 15 + 20 + 20 = 94

Answer: 94 cm squared

Answer:

The slope of 2 is -1/2

The slope of 3 is 3/2

Answer:

#2 is -1/2 and #3 is 3/2

Step-by-step explanation:

using rise over run you can find slope in both. in the first one it's a negative slope, as the rise is -1 and the run is 2. same with the 3rd one

Answer:

[tex]m\angle WZY = 24^\circ[/tex]

Step-by-step explanation:

Angles and Lines

The figure shows two triangles WXZ and WYZ. Considering:

* Angles WXZ and WYZ are right (90°)

* Sides XW and YW are congruent (red marker on both)

* They share the side WZ.

We can conclude they are congruent. Thus, angles XZW and YZW are congruent or have the same measure:

5x + 4 = 6x

Subtracting 5x:

4 = x

Or, x =4

Thus:

[tex]m\angle WZY = 6x = 24^\circ[/tex]

[tex]\mathbf{m\angle WZY = 24^\circ}[/tex]

Step-by-step explanation:  

Answer:

24

Step-by-step explanation:

Using ratios, we know that PQ/PT = PR/PS = QR/TS

of course, we know this because of AA similarity.

PQ/PT = 1/2

so PR/PS = 1/2 => PS = 12*2 = 24

Answer:

24

Step-by-step explanation:

PQ is half of PT, therefore, if PR = 12, PS = 24  

Answer:

x=1

2x+3=5

-3 -3

now the three gets canceled and 5-3 is 2

2x=2

now divide 2 on both sides

2x÷2=2÷2

x=1

Answer:

[tex]x = 18[/tex]

[tex]y = 6\sqrt{3}[/tex]

Step-by-step explanation:

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios. The longest side of a right triangle is called the hypotenuse and the other two sides are called the legs.  

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides as follows:

Cosine Ratio

[tex]\displaystyle \cos\theta=\frac{\text{adjacent leg}}{\text{hypotenuse}}[/tex]

Sine Ratio

[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

Consider the angle of θ=30°, then we can write:

[tex]\displaystyle \cos 30^\circ=\frac{x}{12\sqrt{3}}[/tex]

Solving for x:

[tex]x=12\sqrt{3}\cos 30^\circ[/tex]

Since:

[tex]\cos 30^\circ=\frac{\sqrt{3}}{2}[/tex]

Then:

[tex]x=12\sqrt{3}\cdot \frac{\sqrt{3}}{2}[/tex]

[tex]x = 18[/tex]

Now apply the sine:

[tex]\displaystyle \sin 30^\circ=\frac{y}{12\sqrt{3}}[/tex]

Solving for y:

[tex]y=12\sqrt{3}\sin 30^\circ[/tex]

Since:

[tex]\sin 30^\circ=\frac{1}{2}[/tex]

Then:

[tex]y=12\sqrt{3}\cdot \frac{1}{2}[/tex]

[tex]y = 6\sqrt{3}[/tex]

Answer:

[tex]x = 18[/tex]

[tex]y = 6\sqrt{3}[/tex]

Answer:

They are parallels

Step-by-step explanation:

Answer:

x1 = 0.52

x2 = -10.1

x3 = 0.97

Step-by-step explanation:

From the question;

x1 = 1 - 3/(x0)^2

x0 = -2.5

x1 = 1- 3/(-2.5)^2

x1 = 1 -0.48

x1 = 0.52

x2 = 1 - 3/(x1)^2

x2 = 1 - 3/0.52^2

x2 = 1 - 11.1

x2 = -10.1

x3 = 1 - 3/(x2)^2

x3 = 1- 3/(-10.1)^2

x3 = 0.97

Answer:

A. y - 4 = 3(x + 2)

Step-by-step explanation:

Point slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line

Plug in the slope and given point:

y - y1 = m(x - x1)

y - 4 = 3(x + 2) is the equation

So, A is the correct answer.

Answer:

y= -3x - 1

Step-by-step explanation:

The graph intercepts y at -3 and the slope is -1

9/4 or 2 1/4

Step-by-step explanation:

2 7 /8 -5/8 which gives you 9/4

Answer:

See below.

Step-by-step explanation:

The domain refers to the x values used in the equation/graph. The line appears to go from -10 to 10 on the x-axis. The dots above -10 and 10 are not shaded in meaning those x values do not count towards the domain meaning we will use parenthesis instead of brackets for interval notation or no equal to signs in inequality notation.

Interval Notation: (-10, 10)

Inequality Notation: -10 < x < 10

Answer: 5.25

Step-by-step explanation: .35*15=5.25

Answer:

5.25

Step-by-step explanation:

change the percent to a decimal by moving the dot to the left two places, then multiply it by the number

0.35*15=5.25

Answer:

m⁹

Step-by-step explanation:

In such questions , when any two or more numbers with exponents are multiplied and their bases are equal , the exponents of all the numbers add up . So ,

[tex]m^{5} \times m^{4} = m^{5+4} = m^{9}[/tex]

Step-by-step explanation:

y = mx + c

When x = 0, y = 2.

=> (2) = m(0) + c, c = 2.

When x = 3, y = 8.

=> (8) = m(3) + 2, 3m = 6, m = 2.

Hence the answer is y = 2x + 2.

Answer:

x > 4.5

Step-by-step explanation:

Given the inequality :

14.4x - 28.2 > 36.6

Collect like terms

14.4x > 36.6 + 28.2

14.4x > 64.8

Divide both sides by 14.4

x > 64.8 / 14.4

x > 4.5

Answer:

guess what I don't know

Step-by-step explanation:

Answer:

(3x+21)(x-5)

Step-by-step explanation:

To solve this let's create an equation that has intercepts at -7 and 5

To do this we get the following

(x+7)(x-5)

Now we need to make sure that the line passes through (4,-33) To do so we will plug in 4 to see how far off we are

If you plug in 4 into x you should get -11

To make y= -33 we simply need to put a three in the front and then distribute it to the first bracket

So we have

3(x+7)(x-5)

then distribute the 3 to get

(3x+21)(x-5)

I doubled checked this answer on desmos and my math is correct
