solve for me please this is trigonometry

Answer:

Step-by-step explanation:

Perimeter:

Perimeter = 2*(length +width}

                [tex]=2*(10x-15+\dfrac{1}{5})\\\\\\=2*(10x - \dfrac{15*5}{1*5}+\dfrac{1}{5})\\\\\\=2*(10x -\dfrac{75}{5}+\dfrac{1}{5})\\\\\\=2*(10x -\dfrac{74}{5})\\\\= 20x - \dfrac{148}{5}[/tex]

Area:

        Area  = length * width

                 [tex]= \dfrac{1}{5}*(10x-15)\\\\\\=\dfrac{1}{5}*10x - \dfrac{1}{5}*15\\\\\\=2x - 3[/tex]

x = 10

Perimeter = 20*10 - (148/5)

                 [tex]=200- \dfrac{148}{5}\\\\= \dfrac{200*5}{1*5}-\dfrac{148}{5}\\\\=\dfrac{1000-148}{5}\\\\=\dfrac{852}{5}\\\\=170.4[/tex]

Answer:

1.)-29 3/5 + 20x 2.)2x-15 3.)85 1/5

Step-by-step explanation:

you have 4 sides of a rectangle and to solve for the perimeter of a rectangle you have to add up all four sides. you have the width of the rectangle and the length. SO add them up once then multiply it by two.

If your trying to find the area you multiply L*W=A^2 so just multiply your length and width.

If the x was 10 just plug in you x and solve.

It gets tricky with the variable x and I'm guessing that's where you getting caught up.

for the first one you would have 1/5 + 10x - 15 then you want to multiply it by two getting -29 3/5 + 20x that's the equation you'd use for the first expression.  for the second one you want to find the area so 1/5 * 10x-15 you'd then want to simplify it which would be 2x-15

and for the third one. You have the length and the width so the perimeter is calculated by (1/5 + 10(10)-15)2 1/5+100-15  and you get 85 1/5

Sorry if this is wrong.

Answer:

5

Step-by-step explanation:

A slope of -4 means that for every x increase by 1, the y decreases by 4. so going from (8,9) to (9,w), w should be 9-4, which is 5

Answer: A function is continuous when its graph is a single unbroken curve ... ... that you could draw without lifting your pen from the paper.

Step-by-step explanation:

0.4/0.8

= 4/10 × 10/8

= 4/8

= 1/2

= 0.5

0.5 is a RATIONAL number (A).

=》0.5 is a rational number because it's in the form of p/q (5/10) where both p & q are integers & q is not equal to 0.

=》 Also, q can be expressed in the form of 2ⁿ × 5ᵐ (q = 10 = 2¹ × 5¹) which makes it a rational number.

Answer:

[Option 1] Wayne ascends at a faster speed

[Option 5] Wayne was deeper when he began ascending

Step-by-step explanation:

Taking out important pieces:

[] Wayne = y = 30x - 105

[] Winston = Table

[] They are going from negative to 0, so the slope is positive

Solving:

Let's fine out some points for Wayne, to make it easy, we will plug in the same x values in Winston's Table

y = 30x - 105 ->  y = 30(0) - 105 -> y = -105

y = 30x - 105 ->  y = 30(3) - 105 -> y = -15

So Wayne is (0, -105) & (3, -15), and from the table Winston is (0, -100) & (3, -16)

Answering:

Because at 3 seconds Winston was at -16 and Wayne was at -15, then option 1 is also correct.

Since Wayne started 5 feet deeper, option 5 is correct.

Have a nice day!

Step-by-step explanation:

Answer:

The initial value, or y-intercept, is the output value when the input of a linear function is zero. It is the y- value of the point at which the line crosses the y-axis. An increasing linear function results in a graph that slants upward from left to right and has a positive slope. Which statement best describes a geometric sequence?

Answer: The slope should be 2/3

Step-by-step explanation: Slope is rise over run. Remember you always rise before you run. So in this case you start at the origin and go up until you get to the point on the line where the line is centered. You go up 3 times and thats where the first actual point is. Then move to the side until you get to the line which is 2 to the right. so therefore your answer is 3/2

Answer:

b=4

Step-by-step explanation:

b=4 because 10 x 4 is 40.

Step-by-step explanation:

-26a-19-35=-84

-26a-19+(19)-35=-84+(19)

-26a-35=-65

-26a-35+(35)=-65+(35)

-26a=-30

-26a/26=-30/26

Answer:

525

Step-by-step explanation:

Let the number be " x ".

1 / 5 of x is 105

x / 5 = 105

x = 105 x 5

x = 525

Therefore,

the number is 525.

Answer:

Step-by-step explanation:

1/5 of a number is 105, and the number is

105 * 5 = 525

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

check

525 * 1/5 = 105

the answer is good

Answer: Tissue

Step-by-step explanation:

They work together and there are in similar group.

Step-by-step explanation:

when 2 triangles are similar, it means that both have the same angles. and that then all the corresponding side lengths relate to each other by the same multiplication factor.

PQ and ST are corresponding sides.

the length of ST (4) is the length of PQ (16) multiplied by 1/4.

16 × 1/4 = 4.

the same factor (1/4) also applies to the other sides.

and therefore,

TU = QR × 1/4 = 19.2 × 1/4 = 19.2/4 = 4.8

6 is a number known for being combined with 3 more 6's to create Satans Code

Answer:

First, let’s rearrange the equation in terms of y:

y = -2.5x + 6

We can input the coefficient of x (the gradient of the line) above into this equation:

y - y1 = m (x - x1)

Where y1, is the y value of an arbitrary point in the line, m is the gradient of the line, and x1 is the corresponding x value of the same arbitrary point in the line for y1.

So, putting it in we get:

y - 4 = -2.5(x +2)

y -4 = -2.5x - 5

y = -2.5x -1

Answer:

124

Step-by-step explanation:

73 to 0 is 73

0 to -51 is -51 hence

(+73)-(-51)

124

the distance between 73 and -51 on a number line is 124 units.

Given is the distance between 73 and -51 on a number line

Let the distance between 73 and -51 on a number line be [ΔN]. Then, we can write -

N{1} = 73

N{2} = - 51

ΔN = |N{2} - N{1}|

ΔN = |-51 - 73|

ΔN = |- 124|

ΔN = 124

Therefore, the distance between 73 and -51 on a number line is 124 units.
