Answer:

[tex]\boxed {\boxed {\sf About \ 28.36 \ meters }}[/tex]

Step-by-step explanation:

Assuming the tree is perpendicular to the ground, we can use the right triangle trigonometric ratios to find the tree's height.

Now, let's draw a diagram. We know Aiko is 5 meters from the base of the tree. From there, the angle to the top of the tree is 80 degrees. We are looking for x, the tree's height. The diagram attached is not to scale.

We base the sides off of the angle. x is opposite of 80 degrees and 5 is adjacent. Therefore we must use tangent.

[tex]tan(\Theta)=\frac{opposite}{adjacent}[/tex]

Substitute in the known variables.

[tex]tan(80)=\frac{x}{5 \ m }[/tex]

We want to find x, the height of the tree. Therefore we need to isolate that variable.

x is being divided and the inverse operation is multiplication. Multiply both sides of the equation by 5 meters.

[tex]5 \ m* tan(80)=\frac{x}{5 \ m }* 5 \ m[/tex]

[tex]5 \ m* tan(80)=x[/tex]

[tex]5 \ m *5.67128182=x[/tex]

[tex]28.3564091 \ m = x[/tex]

The question asks for an approximation, so let's round to the nearest hundredth.

The 6 in the thousandth place tells us to round the 5 to a 6.

[tex]28.36 \ m \approx x[/tex]

The tree is about 28.36 meters tall.

Answer:10000

Step-by-step explanation:

Remember that log x and 10^x are inverse functions.

If you have log x = 4 and want the value of x, write this out:

log x 4

10 = 10

This simplifies to:

x = 10^4, and so the fourth answer choice is the correct one.

Answer:

  a6 = -196,608

Step-by-step explanation:

The general term of a geometric sequence with first term a1 and common ratio r is given by ...

  an = a1·r^(n-1)

For a1 = 6, r = -8, and n = 6, we find the 6th term to be ...

  a6 = 6·(-8)^(6-1)

  a6 = -196,608

Answer:

$24

Step-by-step explanation:

Let the total amount of her allowance = a

We are told that she spent $8 on belt

And the total amount she spent = $22

The Fraction of allowance spent on

Shirt = 1/4

Skirt = 1/3

Hence, the equation is given as:

1/4 × a + 1/3 × a + $8 = $22

Collect like terms

a/4 + a/3 = $22 - $8

a/4 + a/3 = $14

The Lowest Common Denominator = 12

3a + 4a/12 = $14

7a/12 = $14

Cross Multiply

7a = $14 × 12

7a = $168

a = $168/7

a = $24

Therefore, her total allowance = $24

Answer:

its 24 i took the quiz :)

Answer:

[tex]\huge\boxed{\sf S = 8}[/tex]

Step-by-step explanation:

Opposite sides and angles of a ║gm are equal.

So,

6S - 8 = 3S + 16

6S - 3S = 16 + 8

3S = 24

Divide 3 to both sides

S = 24 / 3

S = 8

Answer:

A

Step-by-step explanation:

we can conclude from the second equation that when

2x + y = 6 then y = 6 - 2x. so instead of y in the first equation we use 6 - 2x.

now the equation would look like this : 6 - 2x = x^2 - 4x + 3 .

then we bring everything to one side of the equation : x^2 - 2x - 3 .

now we'll have two results for x ( because x^2 - 2x - 3 = 0 has 2 answers )

one of them is -1 and other one is 3.

if we put them in the first equation we will have 8 and 0 for y.

so A is the answer

Part of incomplete work = 2/3 of project

Step-by-step explanation:

Given:

Part of work completed = 1/3 of project

Find:

Part of incomplete work

Computation:

Part of incomplete work = 1 - Part of work completed

Part of incomplete work = 1 - 1/3

Part of incomplete work = 2/3 of project

Answer:

28 gallons.

Step-by-step explanation:

1/5 is 20% of the container's full capatcity.

7/10 is 70% of the container's full capatcity.

20% - 70% = 50%

By adding 14 gallons of water, the container's water went up by 50%.

If we multiply 14 by 2, we will know what the container can hold at 100% capatcity.

14 x 2 = 28

y2-y1/x2-x1. For A and B y2=4, y1=-4, x2=2 and x1=-2... Now u plug them in them, 4-(-4)/2-(-2)= 8/4=2. Slope equals 2. :)

Answer:

the price of a medium pizza without a coupon is 14.73

Step-by-step explanation:

The computation of the price of a medium pizza without a coupon is given below:

Given that

The Price of medium pizza be 10.31 after considering the 30% off coupon

That means it is 70% value

So the 100% value would be

= 10.31 × 1 ÷ 0.70

= 14.73

hence, the price of a medium pizza without a coupon is 14.73

Answer:

The area of the shaded figure is:

Step-by-step explanation:

To obtain the area of the shaded figure, first, you must calculate this as a rectangle, with the measurements: wide (4 units), and long (6 units):

How the figure isn't a rectangle, you must subtract the triangle on the top, so, now we calculate the area of that triangle with measurements: wide (4 units), and height (2 units):

In the end, you subtract the area of the triangle to the area of the rectangle, to obtain the area of the shaded figure:

I use the name "units" because the exercise doesn't say if they are feet, inches, or another, but you can replace this in case you need it.

Q

Step-by-step explanation:

X has constant value

x'-x = 0

m =(y'-y)/(x'-x)  --> undefined

Answer:

R

Step-by-step explanation:

A vertical line has a slope that is "undefined". Line R is the vertical line on your graph

___________

The slope of a vertical line is "undefined" because of the way slope is defined. Slope is the vertical change divided by the horizontal change. When the line is vertical, there is no horizontal change, so the computation of slope involves division by zero. The result of division by zero is "undefined."

Answer:

y = - 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, then

y = - 3x + c ← is the partial equation

To find c substitute (- 2, - 1) into the partial equation

- 1 = 6 + c ⇒ c = - 1 - 6 = - 7

y = - 3x - 7 ← equation of line

Answer:

The equation would be y=-3x-7
