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

Find the equation of this line.
9514 1404 393
Answer:
y = 1/2x + 1
Step-by-step explanation:
The slope of the line is "rise"/"run", where "rise" is the vertical distance between two points separated by a horizontal distance of "run".
Here, two points are marked that are 4 units apart horizontally (run = 4). The right-most point is 2 units above the left-most point (rise = 2). The slope between these points is ...
m = rise/run = 2/4 = 1/2
The line crosses the y-axis at y=1, so the "y-intercept" is b=1.
These values can be put into the "slope-intercept form" equation for a line.
y = mx + b . . . . . . line with slope m and y-intercept b
y = 1/2x + 1 . . . . . matches the required answer form

a college loan of 15000 has a 3% annual simple interest rate what is the interest the student will pay after 5 years
Answer:
Interest = $ 90000
Step-by-step explanation:
Given, Principal= $15000
Rate = 3%
Time = 5 years
Interest = P × R × T/100
Therefore, Interest = 15000 × 3 × 5/100
(dividing 100 by 5 to get 20)
= 15000 × 3 × 20
= 90000

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]

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.
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

Lyla is planning on riding his bike no more than 65 miles during the week. She has already ridden 17 miles. Write and solve an inequality to find how many more miles she can ride. Then interpret the solution.
Answer:
17 + m ≤ 65
Step-by-step explanation:
Maximum distance = 65 miles
Number of miles already ridden = 17
Expression to represent how many more miles, 'm' she can ride ;
Number of miles already ridden + m ≤ maximum distance
17 + m ≤ 65
m ≤ 65 - 17
m ≤ 48
The amount of additional miles Lyla can ride is at most 48 miles
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 :)

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)

Answer:
I would say either A or C
Step-by-step explanation:
Solve the following equations. Make sure you show each step of the work including any Distributive Property,
Inverse operations and combining/collecting of like terms that may be needed. Remember that what you do to
one side you must do to the other when using inverse equations. Label your response with the same letter of the
problem AND write the original problem first before you begin to solve.
A) 1d + 12 = 14-20
B) 4(20+5) = 10r
C) -2(5 + x) - 1 = 3(x + 3)
Answer:
A) -18 B) r=10 C) x=-4
Step-by-step explanation:
A) 1d + 12 = 14-20
Step 1: Simplify both sides of the equation.
1d+12=14−20
d+12=14+−20
d+12=(14+−20)(Combine Like Terms)
d+12=−6
d+12=−6
Step 2: Subtract 12 from both sides.
d+12−12=−6−12
d=−18
Answer:
d=−18
B) 4(20+5) = 10r
Step 1: Simplify both sides of the equation.
100=10r
Step 2: Flip the equation.
10r=100
Step 3: Divide both sides by 10.
r=10
C) -2(5 + x) - 1 = 3(x + 3)
Step 1: Simplify both sides of the equation.
−2(5+x)−1=3(x+3)
(−2)(5)+(−2)(x)+−1=(3)(x)+(3)(3)(Distribute)
−10+−2x+−1=3x+9
(−2x)+(−10+−1)=3x+9(Combine Like Terms)
−2x+−11=3x+9
−2x−11=3x+9
Step 2: Subtract 3x from both sides.
−2x−11−3x=3x+9−3x
−5x−11=9
Step 3: Add 11 to both sides.
−5x−11+11=9+11
−5x=20
Step 4: Divide both sides by -5.
x=−4
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:
Same slope
Add 2 to both sides of the equation.
So, I have this half-done equation, and the next step is to add 2 to both sides, how do I do that? Please help with a legit answer, thankyou so much!
x^3=∛(x-2)
Answer:
x = -1.135 (approx).
Step-by-step explanation:
x^3 = ∛(x - 2)
Cube both sides:
x^9 = x - 2
Subtract x and add 2 to both sides:
x^9 - x + 2 = 0
We could solve this for real roots by drawing a graph.
I did this and got one root x = -1.135 (approx).
The other 8 roots are complex.
