Answer:

f[g(x)]= 2(x^2-10)+1

2x^2-20+1

f[g(3)]=2(3)^2-20+1

18-20+1

18-19=-1

The sum of the interior angles of a quadrilateral ___ the sum of its exterior angles. Select one: a. > b. < c. equals
viktelen [127]

Answer:

The sum of the interior angles of a quadrilateral <u>equals</u><u> </u> the sum of its exterior angles.

Step-by-step explanation:

The sum of the exterior angles of a quadrilateral is 360 degrees.

The sum of the interior angles = (n-2)*180

Here n = 4, the number of sides.

Quadrilateral has 4 sides.

The sum of the interior angles = (4 - 2)*180

= 2*180

= 360 degrees.

Therefore, the sum of the interior angles of a quadrilateral <u>equals </u> the sum of its exterior angles.

Hope this will helpful.

Thank you.

A customer deposits $500 in an account that pays 4% annual interest. what is the balance after 3 years if the interest is compou
docker41 [41]
Going to add on to your variables for the sake of the formula.

Let A = the amount after T years. 
P = Principal amount

A = P(1 +  \frac{r}{n})^{nt}

A = 500(1 +  \frac{0.04}{1})^{1(3)}

A = 500(1 +  \frac{0.04}{1})^{3}

A = 562.432 or ≈ $562.43

The customer would have $562.43 at the end of 3 years.

olga_2 [115]

The system of inequalities is x+y≥250 and 3x+2y≤800.

Step-by-step explanation:

Given,

People to invite = at least 250

At least 250 means that the number can increase from 250.

Cups to be provided = only 800

It means the number cannot exceed 800.

Number of adults = A

Number of children = C

According to given statement;

x+y≥250

3x+2y≤800

The system of inequalities is x+y≥250 and 3x+2y≤800.

Angle JKL is an equilateral triangle jk=13x+5 KL=17x-19 and JL=8x+35
Goshia [24]

The value of x is 6, then the value of JK is 83, KL is 83 and JL is 83.

<h3>What is a triangle?</h3>

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

An equilateral triangle is a shape with three sides that have an equal measure of side length.

The 3 sides of triangle JKL are equal to each other, therefore we can equate any of the two sides together to find the unknown variable called x.

So, JK = KL

JK = 13x + 5

KL + 17x - 19

13x + 5 = 17x - 19

Collect like terms;

17x - 13x = 19 + 5

4x = 24

x = 24/4

x = 6

We can now proceed to find the sides;

JK = 13x + 5

13 x 6 + 5

= 78 + 5

= 83

JK = 83

KL = 17x - 19

= 17 x 6 - 19

= 102 - 19

= 83

KL = 83

JL= 8x + 35​

= 8 x 6 + 35

= 48 + 35

= 83

JL = 83

Hence, The value of x is 6, then the value of JK is 83, KL is 83 and JL is 83.
