Answer:

  The sine of the angle = the length of the opposite side. the length of the hypotenuse.

  The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.

  The tangent of the angle = the length of the opposite side. the length of the adjacent side.

Answer:

c = a√2

Step-by-step explanation:

Apply the 45º-45º-90º Triangle Theorem to find the length of the hypotenuse of the triangle.

The area of the triangle based on the information given is 16.67 inches ²

It should be noted that the area of a triangle is given by the formula:

= 1/2 × base × height

In this second figure, the height will be:

= 5.9² - (3.4/2)²

= 5.9² - 1.7²

= 34.81 - 2.89

= 5.65

The area will be:

= 1/2 × base × height

= 1/2 × 5.65 × 5.9

= 16.67 inches ²

C

Answer:

C.  y = 20

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}3y = 18x + 6\\y = 2x + 14\end{cases}[/tex]

Multiply the second equation by 3:

[tex]\implies (3)y=(3)2x+(3)14[/tex]

[tex]\implies 3y=6x+42[/tex]

Subtract this from the first equation to eliminate 3y:

[tex]\begin{array}{r l}3y & = 18x+6\\-\quad3y&=6x+42\\\cline{1-2}0&=12x-36\end{array}[/tex]

Solve the resulting equation for x:

[tex]\implies 12x-36=0[/tex]

[tex]\implies 12x=36[/tex]

[tex]\implies x=3[/tex]

Substitute the found value of x into the original second equation and solve for y:

[tex]\implies y=2(3)+14[/tex]

[tex]\implies y=6+14[/tex]

[tex]\implies y=20[/tex]

Answer: W

Step-by-step explanation:

The graph must pass the vertical line test.

Considering the given quadratic function, the correct statement is given by:

The airplane reaches its maximum height of 95 feet in 10 seconds.

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient. If a > 0, the vertex is a minimum point, and if a < 0 it is a maximum point.

In this problem, the function is:

h(t) = -(t - 10)² + 95.

Hence the vertex is (10, 95), and since a < 0, the correct statement is given by:

The airplane reaches its maximum height of 95 feet in 10 seconds.

Answer: B'(-4, -4)

Given : A(1, 2), B(-1, -1), C(0, -2)

"Focusing on B coordinates"

If the points are dilated with a scale factor of 4

Then new coordinates : (-1, -1) × 4 = B'(-4, -4)

Answer:

B' = (-4, -4)

Step-by-step explanation:

Dilation:  A type of transformation that makes the pre-image larger or smaller without changing its shape.

Center of a dilation:  a fixed point about which all points are dilated.

Given:

For dilation when the center of dilation is the origin (0, 0), simply multiply the coordinates of the vertices of the pre-image by the given scale factor to find the image under dilation:

Therefore:

A' = (1 x 4, 2 x 4) = (4, 8)

B' = (-1 x 4, -1 x 4) = (-4, -4)

C' = (0 x 4, -2 x 4) = (0, -8)

It is line symmetry because you can fold the H, and it would overlap perfectly.

Horizontal and vertical lines because if you were to place a line in the middle both horizontally and vertically it would overlap.

90 and 180 degrees because the H would still have have symmetry if you flipped it on its side or upside down.

The area of the new patio if the original patio measures 13 feet by 13 feet is 133 ft².

Ezra has a square brick patio. he wants to reduce the width by 6 feet and

increase the length by 6 feet.

The area of the square is the measure of the space occupied by it. It is equal to the product of the measure of its two sides.

We need to write the expression for the new patio and the area of the new patio if the original patio measures 13 feet by 13 feet.

let x be the measure of the side of a square.

The length increased by 6 ft, so the new length=x+6.

The width decreased by 6 ft, so the new width=x-6.

The area is the product of length and width, so the new area is

l×w = (x+6)×(x-6)

Since the original side is 13 ft, the new length is 13+6 = 19 ft, and the new width is 13-6=7 ft.

So, the area is (19 ft)×(7 ft) = 133 ft²

Hence, the area of the new patio if the original patio measures 13 feet by 13 feet is 133 ft².

Answer:

3 family members get 126 text messages each

1 family member gets 127 text messages

Step-by-step explanation:

If you were finding the exact division of texts, 505 texts / 4 people, you would end up with 126.25 texts.

However, you can't get 0.25 of a text. If we take back each family member's 0.25 text, they will all be left with 126 texts (with an extra text leftover)

This extra text is considered the "remainder", meaning the amount left over when a number is divided [when it doesn't go into the larger number evenly]. The only importance/relevancy of a remainder is when a value cannot be split, such as a dog or a text.

So, we can give each family member 126 texts, and then we can give one family member an additional text, so that all texts are distributed.

This means that 3 family members get 126 texts, and 1 family member gets 127 texts
