Step-by-step explanation:
[tex]\triangle{PQR}[/tex] is a right triangle. Use the Pythagorean Theorem:
(leg)^2 + (leg)^2 = (hypotenuse)^2
The length of PR is r + 4; it's the hypotenuse.
[tex]PQ^2+QR^2=PR^2[/tex]
[tex]r^2+8^2=(r+4)^2 \\ r^2+64=r^2+8r+16 \\ 64=8r+16 \\ 48=8r \\ 6=r[/tex]
Remember, to expand [tex](r+4)^2[/tex] you multiply [tex](r+4)(r+4)[/tex]
A line passes through the points (2, -4) and (4, 2). What is the equation of this line in slope-intercept form?
A. y = 3x – 10
B. y = 2x – 14
C. y = 3x + 14
D. y = x + 4
Answer:
A.
Step-by-step explanation:
Slope = y2-y1/x2-x1
(2,-4) = (x1,y1)
(4,2) = (x2,y2)
Slope = (2+4)/(4-2)
= 6/2
= 3
Y=mx+b [Plugging (4,2) into this]
2 = 3×4 +b
2 = 12 + b
b = -10

A

A missile is projected vertically up with a velocity of 50 m/s. What is the velocity at the highest point of projection?
A) 50 m/s
B) 25 m/s
C) 5 m/s
D) 0 m/s
Answer:
D) 0 m/s
Step-by-step explanation:
At its highest point in its trajectory, the missle will change directions from going up to down
In order to achieve that, it must have a velocity of 0 m/s
is 3/4 proportional to 6/15
answer:
no
step-by-step explanation:
step one- cross multiply
3*15=4*6
step two- multiply
3*15=45 4*6=24
step three- simplify
45=24
45 and 24 aren't equal, therefore 3/4 and 6/15 are not proportional
good luck :)

Need a little help :,)
Answer:
A a. 25 minutes
Step-by-step explanation:
Let x = time in minutes.
Aquarium I contains y water at time x.
y = 4.6 + 1.2x
Aquarium II contains y water at time x,
y = 54.6 - 0.8x
We want the amounts of water to be equal, so we set the right parts of the equations equal and solve for x, the time in minutes.
4.6 + 1.2x = 54.6 - 0.8x
Subtract 4.6 from both sides.
Add 0.8x to both sides.
2x = 50
Divide both sides by 2.
x = 25
Find the measure of the angle indicated
Answer:
? = 65°
Step-by-step explanation:
180 - 115 = 65° (115° and 65° are supplementary angles)
180 - 65 - 50 = 65° (all triangle interior angles total 180°)
Answer:
The angle at U is 65 degrees
Step-by-step explanation:
1. We know that a straight line is always 180 degrees..
2. We know that the total interior angle of a triangle is always 180 degrees...
With that in mind, we calculate:
First, we find the missing angle at T, (which is found to be 65 degrees), ( solveing for angle at T)
working out:
180= 115+ T
180- 115= 115-115+T
65. = 0 + T
65= T
Now knowing two angles in our triangle, we are now able to calculate the unknown angle ( angle U) using the two angles.
using our knowledge about interior angles of a triangle, we calculate:
180= angle T + anlge U + angle V
180= 65 + U + 50
180= 65+ 50 + U
180= 115 + U
180-115= 115-115 +U
65= 0 + U
65= U
Therefore, angle at U is 65 degrees...

The end points of PG are given. Find the length of segment PQ using the Pythagorean therom p(-4.3) and q(0,5)
Answer:
4.5 cm
Step-by-step explanation:
Given that the end points of PG are given. Find the length of segment PQ using the Pythagorean theorom p(-4.3) and q(0,5)
Solution
Using the formula;
Length PQ = sqrt ( (X - x)^2 + ( Y - y)^2 )
Length PQ = sqrt( ( 0 + 4 )^2 + ( 5 - 3 )^2)
Length pq = sqrt ( 4^2 + 2^2)
Length PQ = sqrt ( 16 + 4 )
Length PQ = sqrt ( 20 )
Length PQ = 4.47 cm
Therefore , the length PQ is 4.5 cm approximately.

If 2A:3B =5:6 and 3B:2C =36:15, then find A:C
Answer:
Step-by-step explanation:
2A:3B
= 5:6
3B:2C
= 36:15
A:C
= ?:?
2A/3B x 3B/2C
=5/6 x 36/15
=1/1 x 6/3
=1/1 x 2/1
=2
3B and 3B got canceled
For 2A and 2C, the 2 in front of A and C, got canceled as we are cross multiplying.
So I think the answer is
A:C
=1:1 ??
My answer could be wrong.

Does the function f(x) = 2(x-2)^2+3 have a minimum or a maximum? What is the minimum or maximum? Justify your answer.
Answer:
Hello. It does have a maximum and minimum. You would have to use the formula x=-b/2a to find both of them. So first you have the equation which is x=2(x-2)^2+3, which you would have to make it an equation which is equals to F(x)=2x^2-8x+11. So b would be 8 and a would be 2. Enter them into the formula. So the answers would be (2,3)

Which equation would have a graph that is parallel to the following equation?
Answers choices in photo
Why is it right?
Answer:
D
Step-by-step explanation:
"Parallel" means the lines have the same slope- the fractions need to be equivalent. This almost means if it's negative, like in this case, the slope must be negative. 4/6 is equal to 2/3 and is negative like the one shown.
Answer:
Option C. Y= 4/6x + 6
Step-by-step explanation:
