Equation is 3x+7 + 10x+17 = 180 (there are infinitely many other ways to write the equation)

x = 12

Angles are 43 and 137

==========================================================

Explanation:

The horizontal lines are parallel, so the same side interior angles marked are supplementary. The angles add to 180

(3x+7) + (10x+17) = 180 is the equation, or one variation of such

13x+24 = 180

13x = 180-24

13x = 156

x = 156/13

x = 12 is the value of x

Use this x value to find the measure of each angle

3x+7 = 3*12+7 = 43

10x+17 = 10*12+17 = 137

The two angles are 43 and 137 degrees

Note how 43 and 137 add to 180.

A steep hill has a greater slope than a flat plain. What does the slope of the line on a graph describe?

oee [108]

The slope of a line on a graph describes how "steep" the curve is by using the rise divided by the run (y=mx+b). The slope on the line graph usually represents how much of an increase or decrease is occurring per each unit

Please help me with this

Igoryamba

Answer:

D. $\sqrt{250}$

Step-by-step explanation:

First, use prime factorization of 250 to get $\sqrt{2*5^3}$

Then apply the exponent rule, $a^{b+c} =a^{b}*a^{c}$

= $\sqrt{2*5^2*5} }$

Apply radical rule: $\sqrt{ab}= \sqrt{a} \sqrt{b}, a\geq 0, b\geq 0$

= $\sqrt{5^{2}} \sqrt{2*5}$

Apply radical rule: $\sqrt{a^{2}} =a, a\geq 0$

=5 $\sqrt{2*5}$

=5 $\sqrt{10}$

What does the pair of equations y = 5, z = 6 represent? In other words, describe the set of points (x, y, z) such that y = 5 and

stiks02 [169]

Answer:

Option b.

Step-by-step explanation:

The set of points (x, y, z) such that y = 5 and z = 6.

So, all pairs are in the form of (x,5,6).

where, x can be any real number.

It the set of points (x,y,6), y and z-coordinates are constant.

So, the pair of equations y = 5, z = 6 represents a line parallel to x-axis and the distance of this line from xy-plane is 6 units and from xz plane is 5 units.

Therefore, the correct option is b.

Find the area of the following regions, expressing your results in terms of the positive integer n â‰¥ 2. The region bounded by

cluponka [151]

Answer:

The area of the searched region is $A= a+b+ \frac{2n}{n+1}- \frac{n(a^{\frac{n+1}{n} }+b^{\frac{n+1}{n} }) }{n+1}-2$

Step-by-step explanation:

If you want to find the area of a region bounded by functions f(x) and G(x) between two limits (a,b), you have to do a double integral. you must first know which of the functions is greater than the other for the entire domain.

In this case, for 0<x<1, f(x)<g(x)

while for 1<x, g(x)<f(x).

Therefore if our domain is all real numbers superior to 0 (where the limit 0<a<1 and 1<b), we have to do 2 integrals:

A=A(a<x<1)+A(1<x<b)

$A(a$

$A(1$

$A=a-1 +\frac{n}{n+1} - \frac{na^{\frac{n+1}{n} } }{n+1} + b-1 + \frac{n}{n+1} - \frac{nb^{\frac{n+1}{n} } }{n+1} = a+b+ \frac{2n}{n+1} - \frac{n(a^{\frac{n+1}{n} }+b^{\frac{n+1}{n} }) }{n+1} -2$
