Hello There!

Just look at the axis:
When x is -2, what is y?
As you can see on the graph it is 2
Therefore, your answer is :

F(-2) = 2

Hope This Helps You!
Good Luck :)

F(-2).....this is basically saying that when x = -2, what is y

so f(-2) = 2

because f(x) is the same as y...but when u have f(-2)....this is saying x = -2 and they are wanting to know what y is....and when x = -2, y = 2....so f(-2) = 2

After 10 weeks of work, bob has $1200. After 15 weeks of work Bob has $1800. After 20 weeks of work Bob has $2400. Write the fir

lozanna [386]

Answer:

1200,1800,2400,3000

5x = 600x

Step-by-step explanation:

The first four terms would be

1200,1800,2400,3000

As we can see that

After 10 weeks of work bob has $1200

After 15 weeks of work, bob has $1,800

So the more the weeks would be, the more the earnings it is

And, the difference of the earnings is

= $1,800 -$1,200

= $600

The equation would be

5x = 600x

So if we assume x = 1

5 = 600

if we assume x = 2

10 = 1200

and so on

Find the value of x in the isosceles triangle shown below.

dybincka [34]

Answer:

x=8

Step-by-step explanation:

This isosceles triangle is composed of two right triangles with sides 8, $\sqrt{80}$ , and y

As we have two sides of a right triangle, we can find the third using the Pythagorean Theorem

$(\sqrt{80} )^2=8^2+y^2\\\\80=64+y^2\\\\y^2=16\\\\y=4$

As this is an isosceles triangle, these two right triangles are equal, this means that x=2y

Therefore, x=2(4)=8

Should be pretty easy to answer, I just need a refresher. I forgot how to solve for triangles...

Answer:

x = 25.734083

$x \approx 25.734$

Step-by-step explanation:

<u>Trigonometric Ratios</u>

The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

Note we are given an angle of 25°. The opposite side is 12 and the adjacent side is x. We need to relate those sides with a trig function (the tangent ratio)

Tangent Ratio:

$\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}$

Substituting:

$\displaystyle \tan 25^\circ=\frac{12}{x}$

Solving for x:

$\displaystyle x=\frac{12}{\tan 25^\circ}$

Calculating:

$\displaystyle x=\frac{12}{0.466307}$

x = 25.734083

Round to 3 decimals:

$\mathbf{x \approx 25.734}$

An investment of $100 is now valued at $149.18 the interest rate is 8% compounded continuously about how long has the money been

deff fn [24]

question: An investment of $100 is now valued at $149.18 the interest rate is 8% per year, compounded continuously about how long has the money been invested

Answer:

5.2 years

Step-by-step explanation:

Applying

A = P(1+R/100)ⁿ.......................... Equation 1

Where A = amount, P = principle, R = rate, n = time.

From the question,

Given: A = $149.18, P = $100, R = 8%

Substitute these values into equation 1 and solve for n

149.18 = 100(1+8/100)ⁿ

149.18/100 = (1+8/100)ⁿ

1.4918 = (1+0.08)ⁿ

1.4918 = (1.08)ⁿ

Taking the Logarithm of both side

Log(1.4918) = Log(1.08)ⁿ

Log(1.4918) = nLog(1.08)

n = Log(1.4918)/Log(1.08)

n = 0.1737/0.0334

n = 5.2 years.
