Answer:

[tex]A = \sqrt{89}[/tex]

[tex]B = \sqrt{145}[/tex]

Step-by-step explanation:

[tex]1)\ 8^2 + 5^2 = A^2[/tex]

[tex]2)\ A^2 = 64 + 25[/tex]

[tex]3)\ A^2 = 89[/tex]

[tex]4)\ A = \sqrt{89}[/tex]

[tex]1)\ B^2 + 12^2 = 17^2[/tex]

[tex]2)\ B^2 + 144 = 289[/tex]

[tex]3)\ B^2 = 145[/tex]

[tex]B = \sqrt{145}[/tex]

Answer:

a = 9.4

b = 12.0

Step-by-step explanation: For both of these problems, you need to use the Pythagorean Theorum since they are both right triangles, which is represented by the equation a^2+b^2=c^2. In this equation, "c" represents the hypotenuse of the triangle while both "a" and "b" represent the two other sides. In the first triangle, solve the equation 8^2+5^2=c^2 andf in the second triangle, solve the equation 12^2+b^2=17^2 since the hypotenuse is already given.

Answer:

4

Step-by-step explanation:

→ –36 – ( –40 )

→ –36 + 40

→ 4

[tex] \therefore [/tex] 4 is the required answer.

Answer:

The squares would be 2

First one would be 2 × 2 × 2 = 8

The triangles would be 3

Second one would be 2 × 3 × 3 × 3 = 54

Circles would be 1

Third one would be 2 × 3 × 1 × 1 = 6

So that means the last one would be 1 × 2 × 3 = 6

Answer:

[tex]-\sqrt{2}[/tex] and [tex]\sqrt{13}[/tex]

Step-by-step explanation:

Given a polynomial with rational coefficients, its irrational and complex roots would occur in conjugate pairs.

For example, if the roots of a polynomial are 2 + [tex]\sqrt{3}[/tex], 3 and 4 - 3i, then 2 - [tex]\sqrt{3}[/tex], and 4 + 3i are also roots of the polynomial.

Therefore, since the given polynomial has rational coefficients and some of its roots are , [tex]\sqrt{2}[/tex] and  - [tex]\sqrt{13}[/tex], then -[tex]\sqrt{2}[/tex] and [tex]\sqrt{13}[/tex] are also roots of the polynomial.

(- 4, 2 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = A (- 2, 8) and (x₂, y₂ ) = B (- 6, - 4) , then

midpoint = ( [tex]\frac{-2-6}{2}[/tex], [tex]\frac{8-4}{2}[/tex] ) = ( [tex]\frac{-8}{2}[/tex], [tex]\frac{4}{2}[/tex] ) = (- 4, 2 )

Answer:

85.1 ft

Step-by-step explanation:

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x

We solve using the Trigonometric function of Cosine

cos y = adjacent/hypotenuse

y = angle = 20°

Adjacent = 80 ft

Hypotenuse = ?

cos 20 = 80/Hypotenuse

Hypotenuse = 80/cos 20

x = 85.134221798 ft

Approximately = 85.1 ft

Length of the slide = 85.1 ft

Answer:

Part A

The angular difference of their longitude is approximately 50.65°

Part B

The location of B is on the longitude of approximately 30.65°E

Step-by-step explanation:

Part A

The given parameters are;

The location of the points A and B = Along the parallel of latitude 60°

The radius of the Earth, R = 6,371 km

The radius at the 60° parallel of latitude, r = R × cos(θ)

∴ r = 6,371 × cos(60°) = 3,185.5

The circumference of the 60° parallel of latitude, C₆₀ = 2 × π × 3,185.5

The angle subtended by the arc formed by their distance apart, θ₁, is given as follows;

θ₁ = 2,816/(2 × π × 3,185.5) × 360 ≈ 50.65°

The angular difference of their longitude, θ₁ ≈ 50.65°

Part B

Given that the location of A is on the longitude 20°W and A is due west of B, we have the location of B is on the longitude (50.65° - 20°)E = 30.65°E

The location of B is on the longitude of approximately 30.65°E.

Answer:

1. C

2. D

Step-by-step explanation:

Answer:

For the first question it is C(3rd one) and for the second question it is D(last one)

Step-by-step explanation:

So lets think about what we know here.

We know that Lena was walking at a normal speed.

Then she stopped.

Then she moved slowly.

Since x is time, and y is distance from school, we know that x is going to costantly change, while y will depend on what is happening.

First off, we know she is goiong to school. now away from it. This means that any graph with a increasse in the y value will be incorrect. This gets rid of a and b, whihc are the first two answers.

So y should go up nomrallu, since she was just walking at first.

Now, we know that the distance from school must stop, and then begin to decrease at a slower pace. When lookking at the graphs, only C continues to decrease, while D is constantly not moving.

So the answer is C.

Next.

we know that kala drives at a constant speed.

We  know she starts going faster.

Then she slows down.

So we can isntantly remove any graph that completly stops in speed, which means y would be 0, since she is always moving. This gets rid of A and B.

Then we have  C and D

Well, remember that after Kala is going at a normal speed, she sped up.

Only one graph has a large spike in speed after a constant speed. THis is D.

So the answer must be D

Hope this helps!

Answer: Any of the following angles are not congruent to angle 5.

The only exception being that if angle 5 is 90 degrees, then so are the remaining four angles shown above (in fact, all 8 angles are right angles).

========================================================

Explanation:

Angles 2 and 5 are supplementary since line p is parallel to line r. This means angle 2 and angle 5 add to 180 degrees. The two angles are only congruent if both are right angles (aka 90 degree angles); otherwise, they are not congruent angles.

Angle 2 = angle 4 because they are vertical angles. So because these two angles are congruent, and angle 2 does not have the same measure as angle 5, this consequently leads to angle 4 also not being the same measure as angle 5 (unless both are right angles).

Angle 2 = angle 8 because they are alternate interior angles. Following the same logic path as the last paragraph, we see that angles 8 and angle 5 aren't the same measure. Or we could note that angle 5 and angle 8 form a straight angle, so they must add to 180 degrees. The two angles are only congruent if they were 90 degrees each, or otherwise not congruent at all.

Similar logic can also show that angle 6 is not congruent to angle 5.

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

An alternative path is to find all the angles that are always congruent to angle 5 and they are...

And everything else is not congruent to angle 5.

Answer:

C

Step-by-step explanation:

a is wrong because residuals are solved using y and not x

b is wrong because a residual closer to 0 would be more accurate, but f is less accurate than g

c is right because residuals are solved using y and a more accurate residual would be closer to the real answer's y value

Answer:

y = 4.75x + 4

Step-by-step explanation:

it would be $4.75 for each game and you would only pay for shows once

The equation that represents the amount, in dollars, y,

for x games bowled is y = 4.00 + 4.75x

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

The cost for bowling includes a fixed cost of $4.00 for shoes, and an additional cost of $4.75 for each game bowled.

y = 4.00 + 4.75x

This equation can be interpreted as follows: the fixed cost of $4.00 is added to the variable cost of $4.75 per game, multiplied by the number of games bowled (x).

The result is the total cost, represented by y

Therefore,

The total cost for x games bowled can be represented by the equation:

y = 4.00 + 4.75x

where y is the total cost in dollars, and x is the number of games bowled.

Step-by-step explanation:

The dimensions of the cuboid are 5 cm, 7 cm and 9 cm.

The formula for the surface area of the cuboid is as follows :

[tex]A=2(lb+bh+hl)[/tex]

We have,

b = 9 cm, l = 7 cm and h = 5 cm

So,

[tex]A=2(9\times 7+9\times 5+7\times 5)\\\\A=2\times 143\\\\A=286\ cm^2[/tex]

Jamie forgets to multiply 143 by 2 as the formula for surface area contains 2 as well.

Answer: B

Step-by-step explanation: To get the boys part of the ratio you will have to subtract 30 students and 14 students that are girls because all together there are 30 students and since we only know that 14 of them are girls that leaves the rest of the students boys. 30 - 14 = 16  so now we know how many boys there are. 16:14 can be reduced by 2 and that equals to 8:7.

Hope this helps!

The ratio of boys to girls is equal to: B. 8 :7

Given the following data:

To calculate the ratio of boys to girls:

First of all, we would determine the number of boys in the art class by subtracting the number of girl students from the total number of students in this class.

[tex]Total \;students = boys + girls\\\\30=boys + 14\\\\Boys =30-14[/tex]

Boys = 16 students.
