[tex]\tan 39 \textdegree = \displaystyle \frac{h}{89}\\\\89\tan 39 \textdegree = h\\\\h = 72[/tex]Answer:

72 m

Step-by-step explanation:

Hi there!

Using the given information, we can construct a diagram. Please see the attached image.

We need to solve for the height of the building, or the length of the side opposite the angle that measures 39°. Given the only other piece of information is the length of its adjacent side, which is 89 m, we can use the tangent ratio to solve for the height:

[tex]\tan \theta = \displaystyle \frac{opposite}{adjacent}[/tex]

Plug in the given values:

tan 39° = h/89

89 tan 39° = h

h = 72

Therefore, the height of the building is 72 m.

I hope this helps!

The height of the ramp is 49.45in

Data;

To solve this problem, we can use trigonometric ratio SOHCAHTOA

Since we have the value of the angle and length of the ramp, this can be illustrated as hypotenuse and angle between the hypotenuse and opposite of the right-angle triangle.

From the information above, we have angle and hypothenuse but we need to solve for the opposite of the right-angle triangle. The sine angle can solve this problem.

[tex]sin \theta = \frac{opposite}{hypothenuse} \\sin 22 = \frac{x}{132} \\x = 132 sin 22\\x = 49.45 in[/tex]

The height of the ramp is 49.45in

Answer:

350+150m=total money

11 months

Step-by-step explanation:

you just put in the number of months that have passed in for m and solve for total money.

After how many months will Paul have $2,000?

350+150m=2000

350-350+150m=2000-350

150m=1650

150m/150=1650/150

Step-by-step explanation:

A circle that passes through point 0,2 and (0,8) and has a center that lies on x=4 is what given.

So we know is center (4,p) for some number p,

Since the points on circumference of the circle have the same x value, then we know that the y coordinate of the center must be the midpoint of the circumferences' y coordinates.

Why?

A circle is not a function since it doesn't pass the vertical line test. And the standard form of a circle is

[tex] {x}^{2} + {y}^{2} = {r}^{2} [/tex]

With center (0,0).

Consider the equation

[tex] {x}^{2} + {y}^{2} = 9[/tex]

The radius is 3 so two points with x coordinate 0 is

(0,3) and (0,-3). And the midpoint of them is (0,0) which is the center. Which is the defining trait of all circles.

Now, back on hand, our the midpoint of 2 and 8 is 5 so our center is

(4,5).

Now, we must find the radius. We use distance formula.

For (4,5) and (0,8).

[tex]d = \sqrt{(8 - 5) {}^{2} + ({0 - 4) {}^{2} } } [/tex]

[tex]d = \sqrt{3 {}^{2} + {4}^{2} } [/tex]

[tex]d = \sqrt{25} [/tex]

[tex]d = 5[/tex]

So our radius is 5.

So now we use the equation of center h,k.

[tex](x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]

H is 4

K is 5

[tex](x - 4) {}^{2} + (y - 5) {}^{2} = 25[/tex]

Answer:

y = -6x + 7

Step-by-step explanation:

Slope-intercept form: y = mx + b

where:

Given: a line with a slope of -6, and y-intercept of 7

Equation: y = -6x + 7

Randomly select x-values that will help you graph the equation:

when x = -2:

y = -6(-2) + 7 [multiply]

y = 12 + 7 [add]

y = 19

coordinate: (-2, 19)

when x = 1:

y = -6(1) + 7 [multiply]

y = -6 + 7 [add]

y = 1

coordinate: (1, 1)

when x = 2:

y = -6(2) + 7 [multiply]

y = -12 + 7 [add]

y = -5

coordinate: (2, -5)

These coordinates fall on the line for the linear equation. Graph them on a coordinate plane, and they should give you the line for the equation.

Answer:

Yes it is a function. It passes the vertical line test. In other words, it is impossible to draw a single vertical line through more than one point on the V shaped graph. Any input leads to exactly one output.

The domain is the set of all real numbers. This is because we can plug in any x value leading to some specific y value. There are no holes or gaps or jumps to indicate we must restrict any given x value. The domain would not be the set of whole numbers only because values between the whole numbers (eg: decimal values like x = 2.75) work just fine.

The range is the set of y values such that y is either 0 or larger than 0. In short, the range is . Notice how any point on the V shaped graph has a y coordinate that is either 0 or larger than 0. It is impossible to get a y value that is negative.

School (7, 6)

Step-by-step explanation:

E2023

Answer:

see attached diagram

market = (3, 8)

Step-by-step explanation:

Park = (2, 5)

Find the number 2 on the x-axis, then count up 5 units

Park = (2, 5)

x-coordinate:  1 unit to the right = 2 + 1 = 3

y-coordinate: 3 units up = 5 + 3 = 8

Therefore, market = (3, 8)

Answer: I'm not fully sure but I think its 2.07

Answer:

$2.07 per pound

Step-by-step explanation:

we can rewrite 2 2/3 as 8/3

now we can create a proportion from cost to pounds of rice

5.52 is to 8/3 pounds as 'c' is to 1:

(5.52 ÷ 8/3) = c/1

cross-multiply to get:

8/3c = 5.52

multiply each side by 3/8 to get:

c = 5.52(3/8)

c =  2.07

Step-by-step explanation:

Skateboard $125.95 at 40% off is $75.57

How I got the number:

125.95/100 = 1.2595

1.2595 x 40 = 50.38

125.95 - 50.38 = 75.57

Skateboard $169.95 at 60% off is $67.98

169.95/100 = 1.6995

1.6995 x 60 = 101.97

169.95 - 101.97 = 67.98

Therefore the skateboard that is 60% off is cheaper.

Answer:

  10.3 cm

Step-by-step explanation:

There are a few ways to do this.

Using the law of cosines, you have ...

  b² = a² +c² -2ac·cos(B)

  b² = 11² +11² -2(11)(11)·cos(56°) = 106.67

  b = √106.675 ≈ 10.3

  AC = 10.3 cm

__

Using trig functions. When you draw an altitude in this isosceles triangle from B to AC, it divides AC in half, and it divides angle B in half. The sine relation can help here:

  Sin = Opposite/Adjacent

  sin(56°/2) = (AC/2)/(11 cm)

  AC = (22 cm)sin(28°) ≈ 10.3 cm

__

Using a triangle solver, you can find the value of AC to be about 10.3 cm. Triangle solvers are available as apps and on the web. Your graphing calculator may have one. See attached for the results from a nice solver available on the web. Units are cm.
