I NEED HELP WITH ONE OF THESE PLEASE

my teacher didn’t explain to me

Answer:

40

4

Step-by-step explanation:

a.) because the sides are the same their angles must be too

let x be the angle

100+x+x=180

x=40

b.) because the angles are all the same their sides must be too

Answer:

Equation to find the slope

[tex]\frac{y2-y1}{x2-x1} =\frac{-9-0}{3-0} = -9/3 = -3x[/tex]

y=-3x

hope that answers your question

Step-by-step explanation:

Answer: C. y = -3x

Step-by-step explanation:

Since the line runs through the origin (0, 0), we don't have to write a y-intercept. To calculate the slope, we determine the change in y value over the change in x value.

Looking at the graph, we see that for every +1 x, we have -3 y, so the slope is -3, which we multiply by x in the equation.

Answer:

Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values.

Answer:

26

Step-by-step explanation:

[tex] In\: \odot Y, [/tex] WZ is tangent to the circle at point Z and YZ is radius.

[tex] \therefore YZ \perp WZ[/tex]

(tangent radius theorem)

[tex] \therefore m\angle WZY = 90\degree [/tex]

Since, side opposite to 90° angle is called hypotenuse.

So, x represents the length of hypotenuse of [tex] \triangle WYZ[/tex]

Thus, by Pythagoras Theorem

[tex]x = \sqrt{ {24}^{2} + {10}^{2} } \\ \\ = \sqrt{576 + 100} \\ \\ = \sqrt{676} \\ \\ = 26[/tex]

Answer:

this answer is not right because the Y is not 90 degrees the Z angle is 90 degrees so the answer should be 26

if the trangle is right trangle use Phythagoras

576-100=476=x²

x²=476

x=2√119

Answer:

62.83 inches

Step-by-step explanation:

Answer:

8.60

Step-by-step explanation:

the diagram is optically misleading.

how can the 5 side be longer than the 7 side ?

but ignore that.

the important thing is that this is a triangle with a 90 degree angle.

so, we use Pythagoras' formula : a^2 + b^2 = c^2

we know a and b as 7 and 5.

so, the equation is 7^2 + 5^2 = c^2

=> 49 + 25 = c^2

=> 74 = c^2

=> the missing side length c is

[tex] \sqrt{74} = 8.60[/tex]

Answer:

[tex]y= (x -4)^2 - 1[/tex]

[tex]Vertex = (4,-1)[/tex]

Step-by-step explanation:

Given

[tex]f(x) = x^2 + 6x+13[/tex]

Required

7 units left and 5 units down

First, we have: [7 units left]

The rule is:

[tex](x,y) \to (x-7,y)[/tex]

So, we have:

[tex]f(x) = (x - 7)^2 + 6(x -7)+13[/tex]

Next, we have: [5 units down]

The rule is:

[tex](x,y) \to (x,y-5)[/tex]

So, we have:

[tex]f'(x) = (x - 7)^2 + 6(x -7)+13 - 5[/tex]

[tex]f'(x) = (x - 7)^2 + 6(x -7)+8[/tex]

Rewrite as:

[tex]y = (x - 7)^2 + 6(x -7)+8[/tex]

Expand

[tex]y = x^2 - 14x + 49 + 6x -42+8[/tex]

Collect like terms

[tex]y = x^2 - 14x + 6x -42+8+ 49[/tex]

[tex]y = x^2 -8x +15[/tex]

To write in vertex form, we have

Subtract 15 from both sides

[tex]y -15= x^2 -8x[/tex]

Divide (-8) by 2; Add the square to both sides

[tex]y -15+ (-8/2)^2= x^2 -8x + (-8/2)^2[/tex]

[tex]y -15+ 16= x^2 -8x + 16[/tex]

[tex]y +1= x^2 -8x + 16[/tex]

Expand

[tex]y +1= x^2 -4x - 4x + 16[/tex]

Factorize

[tex]y +1= x(x -4) -4(x - 4)[/tex]

Factor out x - 4

[tex]y +1= (x -4)(x - 4)[/tex]

Rewrite as:

[tex]y +1= (x -4)^2[/tex]

Make y the subject

[tex]y= (x -4)^2 - 1[/tex]

The vertex is:

[tex]Vertex = (4,-1)[/tex]

Answer:

No

Step-by-step explanation:

Look at the shape a polygon is 5 sides while a trapezoid has only 4 sides

Answer:

No. :) Reason: Trapezoids have to have at least on pair of parallel lines; this polygon has none.

Answer:

Planet X is 1.77 times further from Earth than Planet Y.

Step-by-step explanation:

Given that Planet X is 23 of a light-year away from Earth, while Planet Y is 13 of a light-year away from Earth, to determine how much farther away is Planet X the following calculation must be performed:

13 = 1

23 = X

23/13 = X

1.769 = X

Therefore, Planet X is 1.77 times further from Earth than Planet Y.

Answer:

let the number be x

The denominator is the bottom number, and represents how many parts are possible—in other words, how many parts go into a whole. The numerator is the top number, and represents how many parts you have.

[tex]\frac{Numerator}{Denominator}[/tex]

Answer:

The numerator is 1.

Step-by-step explanation:

The numerator is the number above the fraction bar; the denominator is below.

Answer:

The volume of the sphere equals 2,393.9 [tex]cm^{3}[/tex] if we were to round to the nearest tenth.

Step-by-step explanation:

The volume of the sphere can be found by using the following formula...

(In the following formula "r" is the radius)

Volume = (4π[tex]r^{3}[/tex]) / 3 = [tex](4)(3.14)(8.3)^{3} / 3[/tex] ≅ 2,393.9 [tex]cm^{3}[/tex]

Answer:

2393.9

Step-by-step explanation:

4πr³/3=4π(8.3)³/3=4π*571.787/3=4*3.14*571.787/3≈2393.9

Answer: [tex]\$1139[/tex]

Step-by-step explanation:

Given

The original cost of the laptop is [tex]\$1340[/tex]

A sale of 15% is applicable on it

The buyer has to pay 15% less

So, the effective price of the laptop is

[tex]\Rightarrow 1340-15\%\times 1340\\\Rightarrow 1340(1-0.15)\\\Rightarrow 1340\times 0.85\\\Rightarrow \$1139[/tex]

So, the final price of the laptop is [tex]\$1139[/tex].
