What’s the area and the perimeter and of the triangle?

asambeis [7]

Answer:

Area = 3.3998

Perimeter = 2.9

Step-by-step explanation:

A method for calculating the area of a triangle when you know the lengths of all three sides.

Let a,b,c be the lengths of the sides of a triangle. The area is given by:

Area = √ p ( p − a ) ( p − b ) ( p − c )

where p is half the perimeter, or

a + b + c / 2

p = 1.7 + 1.7 + 2.4 / 2 = 5.8 / 2 = 2.9

a = Area = 3.3998

Heron was one of the great mathematicians of antiquity and came up with this formula sometime in the first century BC, although it may have been known earlier. He also extended it to the area of quadrilaterals and higher-order polygons.

Given that ƒ(x) = 3x, identify the function g(x) shown in the figure.

pogonyaev

We will see that g(x) is a reflection across the y-axis of f(x), then:

$g(x) = f(-x) = 3^{-x\\$

<h3>How to identify the function g(x)?</h3>

By looking at the graph, we can see that g(x) is a reflection across the y-axis of f(x).

So we can write:

g(x) = f(-x)

Here we know that:

$f(x) = 3^x$

Then, replacing f(x) on the formula for g(x), we get:

$g(x) = f(-x) = 3^{-x\\$

That is the function g(x) shown in the figure.

Find the value of x

AveGali [126]

Answer:

x = 120

Step-by-step explanation:

Since they are supplementary, they add up to 180 degrees.

So, you can say x + x/2 = 180

Then, you would solve it like an algebra problem.

Multiply both sides by 2

2x + x = 360

Simplify

3x = 360

Divide both sides by 3

x = 120

Christina Stratton invested $8,000 in a certificate of deposit for 4 years. The certificate earns interest at an annual rate of

galben [10]

Answer:

6.13%

Step-by-step explanation:

We are given an investment of $8000 deposited for 4 years. We have to find the effective annual yield for which we will need the interest rate and the compounding period.

Annual interest rate compunded quarterly, r = 6% = 0.06

Compounding period is quarterly, n = 4

Annual EffectiveYield = $(1+\frac{r}{n})^{n}-1\\=(1+\frac{0.06 }{4})^{4}-1$

= 0.0613

The annual effective yield is 6.13%
