Find the area of the regular polygon below, rounding to the nearest tenth.

Answers

Answer:

84.3034 m2

Step-by-step explanation:

The area of any regular polygon is given by the formula: Area = (a x p)/2, where a is the length of the apothem and p is the perimeter of the polygon. Plug the values of a and p in the formula and get the area. As an example, let's use a hexagon (6 sides) with a side (s) length of 10.

Find an equation in standard form for the ellipse with the vertical major axis of length 16 and minor axis of length 10.
a. x squared divided by 5 plus y squared divided by 8 = 1

What is an equation of the line that is perpendicular to -x+3y=9 and passes through the point (-3,2)

Answers

Answer:

y=-3x-7

Step-by-step explanation:

the line is currently in standard form (ax+by=c). Let's put it into slope-intercept form (y=mx+b)

-x+3y=9

add x to both sides

3y=x+9

divide by 3

y=1/3x+3

perpendicular lines have slopes that when multiplied, equal -1.

to find the slope (m) of our new line:

1/3m=-1

multiply by 3

m=-3

the slope of the new line is -3

here's our equation so far:

y=-3x+b

we need to find b (y intecept)

since the line passes through the point (-3,2), it should be a solution in the equation (plug it in, and the result is a true statement). We can also use it to find b

so, substitute the pointt into the equation:

2=-3(-3)+b

multiply

2=9+b

subtract

-7=b

so the equation of the line is y=-3x-7

A person invests $2,730 in an account that earns 4.2% annual interest. Find when the value of the investment reaches $5,000. If necessary, round to the nearest tenth.

Answers

Step-by-step explanation:

You want to calculate the interest on $2730 at 4.2% interest per year after 5,000 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:P is the principal amount, $2730.00.

r is the interest rate, 4.2% per year, or in decimal form, 4.2/100=0.042.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 2730 × 0.042 × 5 to get that:

The interest is: $573.30

Maria's cat eats less than 1 cup of food each day. Her cat eats one-third of what Maria's dog eats plus half of a cup. What simplified inequality shows the possible amounts that Maria's dog eats in cups?

Answers

Answer:

[tex]d < \frac{3}{2}x[/tex]

Step-by-step explanation:

Represent a cup with x; the cat with c and the dog with d

From the first statement, we have:

[tex]c < x[/tex]

From the second, we have:

[tex]c = \frac{1}{3}d + \frac{1}{2}x[/tex]

Required

Express d in terms of x

We have:

[tex]c = \frac{1}{3}d + \frac{1}{2}x[/tex] and [tex]c < x[/tex]

Merge both expressions to give:

[tex]\frac{1}{3}d + \frac{1}{2}x < x[/tex]

Collect Like Terms

[tex]\frac{1}{3}d < x - \frac{1}{2}x[/tex]

[tex]\frac{1}{3}d < \frac{1}{2}x[/tex]

Multiply both sides by 3

[tex]3 * \frac{1}{3}d < \frac{1}{2}x * 3[/tex]

[tex]d < \frac{3}{2}x[/tex]

(-8 + -4) /2 = x of M

(-6 + 10)/2 = y of M
