What is the exact area of the following circle?
Answers
Answer:
56.25 pi cm^2
Step-by-step explanation:
To find the area of the circle,
we use the formula
A = pi r^2, where r is the radius
We know the diameter is 15 so we can find the radius from
r = d/2 where d is the diameter
r = 15/2
A = pi ( 15/2) ^2
A = pi ( 225/4)
A = 56.25 pi cm^2
Answer:
2nd option
› 56.25π cm²
Step-by-step explanation:
we know ,
area of circle is πr²
so,
given,
diameter,d = 15cm
radius,r = d/2 = 15/2 = 7.5 cm
so,
area = πr²
= (7.5×7.5)π
= 56.25π cm²

write an equation of a line passing through the point (-4,11) and perpendicular to the line 4x + 5y = -45
Answers
Answer:
y = 5/4x - 6
Step-by-step explanation:
First, put 4x + 5y= -45 in y = mx + b form
4x + 5y= -45
5y = -4x - 45
y = -4/5x - 9
So, the slope is -4/5. Perpendicular lines have a opposite reciprocal slope, so the line's slope will be 5/4 right so to find the equation of the perpendicular line in this question, plug in the slope and given point into y = mx + b, and solve for b
y = mx + b
-11 = 5/4(-4) + b
-11 = -5 + b
-6 = b
so you should Plug in b and the slope into y = mx + b
y = 5/4x - 6
So, the equation is y = 5/4x - 6

A rental car company charges $42.72 per day to rent a car and $0.10 for every mile driven. Zoey wants to rent a car, knowing that:
She plans to drive 200 miles.
She has at most $350 to spend.
Which inequality can be used to determine xx, the maximum number of days Zoey can afford to rent for while staying within her budget?
Answers
Answer:
7 Days
Step-by-step explanation:
Miles cost:
$0.10 * 200 = $20
Daily Cost
Her budget at this point is $330 because $350 - $20 (the miles)
$330 / 42.72 = Roughly 7.72
Therefore Zoey can drive for 7 days before her budget runs out.

Vertex is (-3,0)
Axis of symmetry=x=-3There is only one x intercepts
Only one real root is -3Answer:
vertex = (-3, 0)
axis of symmetry: x = -3
one real root at x = -3
Step-by-step explanation:
The vertex is the turning point of the curve (so the maximum point for parabolas that open downwards, and the minimum point for parabolas that open upwards)
The axis of symmetry is the vertical line that goes through the vertex of a parabola. So this will be the line of the x-value of the vertex.
The roots of a parabola are the points where the curve intersects (or touches) the x-axis.
First graph
vertex = (3, -4)
axis of symmetry: x = 3
roots: x = 1, 5
Second graph
vertex = (-3, 0)
axis of symmetry: x = -3
one real root at x = -3

Answers
1. PEMDAS (order of operations) solve the division problems
(4 divided by 4 & 5 divided by 5)
12x + 1 + 20x + 1
2. Swap around the order of operations as commutative property states that you can swap the order of an addition problem and get the same answer.
12x + 20x + 1 + 1
3. Add like terms
32x + 2
This is the most simplified answer you could get as you can not add 32x and 2 as they are not like terms.

====================================================
Explanation:
Focus on triangles SVT and UVT.
They are congruent triangles due to the fact that SV = VU and VT = VT. From there we can use the LL (leg leg) theorem for right triangles to prove them congruent.
Since the triangles are the same, just mirrored, this means ST = UT = 23.
-----------------------
Following similar reasoning as the previous section, we can prove triangle RVU = triangle RVS.
Therefore, RS = RU = 8
-----------------------
SV = VU = 5 because RT bisects SU.
Bisect means to cut in half. The two smaller pieces are equal.
-----------------------
SU = SV + VU = 5+5 = 10
Refer to the segment addition postulate.
Answer:
ST=23
RU=8
SV=5
SU=10
Step-by-step explanation:
RT bisects the whole quadrilateral, so a line on one side will be the same length as the line on the opposite side of RT. So:
1. ST=UT, UT=23, so ST=23
2. RU=RS, RS=8, so RU=8
3. SV=VU, VU=5, so SV=5
4. SU=2*SV, 5*2=10, so SU=10
If you still have no clue, just imagine the points R, S, T, and the lines connecting them (this will make a triangle). Then reflect the triangle across line RT, and name the new S point U (the new triangle still has the same line measures) . Make a line from S to U and make a point V from where RT and SU meet. This will make the figure in the picture.

A couch and coffee table cost a total of $996. The cost of the couch is two times the cost of the coffee table. Find the cost of each item.
Answers
Answer: the cost of the couch is 664 and the cost of the coffe table is 332
Step-by-step explanation:
X is the cost of the coffee table and 2x is the cost of the couch (which is two times more than the coffee table)
2x + x = $996
3x = $996
x = 996/ 3
x = $332 (this is what the coffee table cost)
2x => 2(332)
2x => $664 (the cost of the couch which is two times the cost of the coffee table)
together, $332 + $664 = $996 total

WILL GIVE BRAINLIEST The mass of a substance, which follows a continuous exponential growth model, is being studied in a lab. A sample increases continuously at a relative rate of 7% per day. Find the mass of the sample after four days if there were 123 grams of the substance present at the beginning of the study.
Do not round any intermediate computations, and round your answer to the nearest tenth.
Answers
Then we know that we originally had 38 grams of the substance, the rate of growth is 18%, and that the time it was allowed to grow is 6 days. Then we have using the exponential growth model that the amount of the sample after 6 days will be S = P e^rt where P is the initial sample amount, r is the rate of growth, t is the time, and S is the final sample amount. S = 38 e^ .18*6 = 38 e ^ 1.08 = 111.8978 Thus if there were 38 grams of the substance present at the beginning of the study the mass of the sample would be 111.8978 grams after the study.
Solve the system of equations 4x + 3y = -25
7x - 3y = -52
Answers
Answer:
x = -7
y = 1
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable x
[2] 7x = 3y - 52
[2] x = 3y/7 - 52/7
// Plug this in for variable x in equation [1]
[1] 4•(3y/7-52/7) + 3y = -25
[1] 33y/7 = 33/7
[1] 33y = 33
// Solve equation [1] for the variable y
[1] 33y = 33
[1] y = 1
// By now we know this much :
x = 3y/7-52/7
y = 1
// Use the y value to solve for x
x = (3/7)(1)-52/7 = -7
Solution :
{x,y} = {-7,1}
