Answer:

90°

Step-by-step explanation:

since PQ is the diameter of the circle, m <em>L</em><em> </em>PRQ = ½ × 180° = 90°.

so, as a supplementary to <em>L</em><em> </em>PRQ, the value of angle QRS = 180 - m <em>L</em><em> </em>PRQ = 180-90 =90°

a) Which relationship is stronger, the relationship between GPA and AGE or the relationship between GPA and SAT score? Be sure t
Bezzdna [24]
GPA and SAT score. your age really has nothing to do with your Gpa. your Gpa is your grade point average, therefore it determines how well you're doing in school. you can have any Gpa at any age, depending on your abilities.

Evalute 2√72 divided by √8+ √2. I need help asap!!!<br><br><br> :( I will mark brainliest pls!!
Ghella [55]

Answer:

It's 4

Step-by-step explanation:

* / = square root

You simply 2/72 which is 12/2, then simplify /8 which is 2/2.

You combine 2/2 and /2 which is 3/2.

The equation should be 12/2 over 3/2 so you simplify it which will give you 4.

(By simplifying 12/2 over 3/2, you cross out /2 and convert 12 over 3 into a whole number)

What is the equation of the circle with center (5,-4) and containing the points (5,-2)
gtnhenbr [62]

Answer:

The equation of a circle is (x-5)^2+(y+4)^2=4 .

Step-by-step explanation:

-The equation of a circle is:

(x-h)^2+(y-k)^2=r^2 (where center is (h,k), the point (x_{1},y_{1}) and the radius known as r).

-Use the center (5,-4) and the point (5,-2) for the equation:

(5-5)^2+(-2+4)^2=r^2

-Solve the equation:

(5-5)^2+(-2+4)^2=r^2

0 + (-2)^2=r^2

4 = r^2

\sqrt{4} = \sqrt{r^2}

2 = r

-After you found the radius, use the center (5, -4)  and radius 2 to get the equation of a circle:

(x-5)^2+(y+4)^2=2^2

-Then, after you have the equation, the radius needs to simplified by the exponent:

(x-5)^2+(y+4)^2=4

Whats the slope and point of y=3x-13
jolli1 [7]
Answer:
slope of line is 3
y-intercept of line is -13

Explanation:
The general formula of the linear line is:
y = mx + c
where:
m is the slope of the line
c is the y-intercept

The given line is:
y = 3x - 13

Comparing the given line with the general formula, we would find that:
m (the slope of the line) is 3
c (the y-intercept) is -13

Hope this helps :)
