can I get some help plz​

Answer:

60.8 inches

Step-by-step explanation:

you can find the height of the triangle by using what you know about the area

A = 1/2bh

950 = 1/2(50)·h

950 = 25h

h = 950/25 = 38

To find hypotenuse you can use the Pythagorean Theorem:

38² + 50² = c²

1444 + 2500 = c²

c² = 3944

c = √3944 ≈ 62.8

Answer:

4

Step-by-step explanation:

(6√5)²+x²=14²

36(5)+x²=196

180+x²=196

x²=196-180

x²=16

x=√16

x=4

Answer:

I. The width is 43.5 inches.

II. The length is 24.5 inches.

Step-by-step explanation:

Let the length and width of the rectangle be L & W respectively.

Given the following data;

Perimeter of rectangle = 136 inches

Translating the word problem into an algebraic expression, we have;

L = W - 19 ......equation 1

Perimeter of rectangle = 2(L + W) ......equation 2

To find the dimensions of the rectangle;

136 = 2(L + W)

Substituting eqn 1 into eqn 2, we have;

136 = 2(W - 19 + W)

136 = 2(2W - 19)

136 = 4W - 38

4W = 136 + 38

4W = 174

W = 174/4

W = 43.5 inches

To find the length;

L = W - 19

L = 43.5 - 19

L = 24.5 inches

Step-by-step explanation:

Given:

The slope of the line is 3.

The line passes through the point (2,-1).

To find:

The equation of the line.

Solution:

Point slope form of a line: If a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the equation of the line is

[tex]y-y_1=m(x-x_1)[/tex]

The line passes through the point (2,-1) with slope 3. So, the equation of the line is

[tex]y-(-1)=3(x-2)[/tex]

[tex]y+1=3(x-2)[/tex]

Therefore, the required equation is [tex]y+1=3(x-2)[/tex]. Hence, all the options are incorrect.

Given:

The graphed point is (60,-20).

To find:

The ordered pair that would form a proportional relationship with the given point.

Solution:

If y is proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

[tex]\dfrac{y}{x}=k[/tex]

Where, k is the constant of proportionality.

For the given point,

[tex]k=\dfrac{-20}{60}[/tex]

[tex]k=\dfrac{-1}{3}[/tex]

For option (A),

[tex]k=\dfrac{30}{-10}[/tex]

[tex]k=-3\neq \dfrac{-1}{3}[/tex]

For option (B),

[tex]k=\dfrac{-15}{30}[/tex]

[tex]k=-\dfrac{1}{2}\neq \dfrac{-1}{3}[/tex]

For option (C),

[tex]k=\dfrac{10}{-30}[/tex]

[tex]k=\dfrac{-1}{3}[/tex].

The point (-30,10) gives the same value of the constant of proportionality. So, the point (-30,10) forms a proportional relationship with the given point.

Therefore, the correct option is C.

Answer:

The correct answer is A

Step-by-step explanation:

Using a recursive sequence means you use the output of the last term as the input for the current term.

In this case your base case is t1=2, therefore:

t2=2(2)-1=3

t3=2(3)-1=5

t4=2(5)-1=9

t5=2(9)-1=17

etc.

Answer:

60

Step-by-step explanation:

Use r-combinations.

Treat it as though u are filling in 6 slots

_ _ _ _ _ _

1. First fill in the 7s, there are three of them and 6 ways to do so

so (6 Choose 3)

2. then fill in the 2s, now with the 3 slots taken up by the 7, 3 slots left.

So its (3 Choose 2).

3. and only 1 way to fill in the 8. (1 choose 1)

By multiplicative rule,

(6C3) * (3C2) * (1C1) = 60

Step-by-step explanation:

The required intercepts of the given ellipse  x²/4 + y²/9 = 1 would be (A) (0, ±3).

A y-intercept, also known as a vertical intercept, is the location where the graph of a function or relation intersects the coordinate system's y-axis.

This is done in analytic geometry using the common convention that the horizontal axis represents the variable x and the vertical axis the variable y.

These points satisfy x = 0 because of this.

So, we have the ellipse:

x²/4 + y²/9 = 1

So, the intercepts would accordingly be:

(0, ±3)

Therefore, the required intercepts of the given ellipse  x²/4 + y²/9 = 1 would be (A) (0, ±3).
