A.SSE.A Carlos borrowed $26,000 for a car for 5 years at an APR of 5.25%. What will his monthly payment be? *
Answer:
$568.75
Step-by-step explanation:
Monthly payment = annual payment / 12
Annual payment = amount borrowed x time x APR
$26,000 X 0.0525 X 5 = $6825
Monthly payment = $6825 / 12 = $568.75
The monthly payment is $568.75 for 5 years at an Annual Percentage Rate (APR) of 5.25%.
The amount borrowed for a car is $26,000.
The time period is 5 years.
The Annual Percentage Rate (APR) is 5.25%.
What is APR?The Annual Percentage Rate (APR) is the cost you pay each year to borrow money, including fees, expressed as a percentage.
Monthly payment = annual payment / 12
Annual payment = amount borrowed x time x APR
Annual payment =$26,000 X 0.0525 X 5
Annual payment = $6825
Monthly payment = $6825 / 12
= $568.75
Hence, the monthly payment is $568.75.

A flag pole and a building stand on the same horizontal level. From the point p at the bottom of a building the angle of the top T of the flagpole is 65°. From the point Q of the building the angle of elevation of the point T is 25°. If the building is 20m high. calvulate the distance PT, The heigt of the flagpole,The distance QT
Answer:
PT is approximately 28.2 m
The height of the flagpole is approximately 25.56 m
QT is approximately 13.15 m
Step-by-step explanation:
Part A
From the attached drawing of the building and the flagpole, we have;
∠TQP = 25° + 90° = 115°
∠TPQ = 90° - 65° = 25°
∴ ∠QTP = 180° - (115° + 25°) = 40°
By sine rule, we have;
[tex]\dfrac{\overline {QT}}{sin(\angle TPQ)} = \dfrac{\overline {PT}}{sin(\angle TQP)} = \dfrac{\overline {QP}}{sin(\angle QTP)}[/tex]
[tex]\therefore \overline {PT} = sin(\angle TQP) \times \dfrac{\overline {QP}}{sin(\angle QTP)}[/tex]
∴ PT = sin(115°) × 20 m/(sin(40°)) = 28.1992924 ≈ 28.2
PT ≈ 28.2 m
Part B
The height of the flagpole, Ta = PT × sin(∠TPa)
∴ Ta ≈ 28.2 × sin(65°) ≈ 25.56
The height of the flagpole, Ta ≈ 25.56 m
Part C
[tex]\overline {QT} = sin(\angle TPQ) \times \dfrac{\overline {QP}}{sin(\angle QTP)}[/tex]
The distance QT= sin(25°) × 20 m/(sin(40°)) ≈ 13.15
QT ≈ 13.15 m

Is 5 a polynomial or not?
Because 5 is represented by the polynomial 5x0, the answer is yes.
A polynomial is a mathematical statement made up of coefficients and indeterminates that uses only the operations addition, subtraction, multiplication, and powers of positive integers of the variables.
An example of a polynomial of a single indeterminate x is x² − 4x + 7.
An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial (No division operation by a variable).
Sums of terms of the form kxn, where k is any number and n is a positive integer, make up polynomials.
For instance, the polynomial 3x+2x-5.
By noticing which formulas only contain the operations of addition, subtraction, multiplication, and non-negative integer exponents, the polynomials may be located. Expressions with additional operations are considered non-polynomial expressions.

Tomas wanted to buy a computer priced at $950. He waited for the store's annual clearnace sale and bought the computer for $712.50. What percent was the discount at the clearnace sale?
Answer:
25%
Step-by-step explanation:
Discount is given by x(1-r) = y, where x is the original price and r is the percentage (made into a decimal) that was discounted, while y is the price after the discount.
So, plugging the numbers given in, we have 950(1-r) = 712.50, as we don't know r. This is hard to find, so we replace (1-r) with m (just a random letter).
Therefore, we have 950m = 712.50. To find m, we divide 712.50 by 950, getting m = 0.75.
That is not our answer. Earlier, we subsituted (1-r) for m. Now, we subsitutite it back. m = 0.75 so 1-r = 0.75. Therefore, we get that r, the discount rate, is equal to 0.25, or 25%.

A.15 pumps
B. 115 pumps
C. 225 pumps
D. 1,829 pumps
The bicycle tire needs an amount of 115 pumps to be fully inflated. (Correct choice: B)
How many pumps are required to inflate the bicycle tire to maximum pressure
In this problem we need to determine the number of pumps needed to inflate the bicycle tire at maximum pressure, this number (n) is equal to the maximum capacity of the tire (V), in ounces, and the mass added by a single pump (p), in ounces:
n = V / p
If we know that V = 640 oz and p = 5.6 oz (1 lb = 16 oz), then the number of pumps is:
n = 640 oz / 5.6 oz
n = 114.286
n = 115

Find the value of x.
Answer:
x = 25
Step-by-step explanation:
The top angle is the supplement of 3x - 10
180 - (3x - 10) = -3x + 190
The sum of the angles in a triangle is 180
(-3x + 190) + (25) + (x + 15) = 180
Combine like terms
-2x + 230 = 180
Subtract 230 from both sides
-2x = -50
Divide both sides by -2
x = 25

What is Probability ?
probability can be defined as the ratio of the number of favourable outcomes and the total number of outcomes.
We are given with an exponential distribution with
λ=0.01386.
The probability distribution function is:
F(x)=λ * e power (−λx)
Cumulative distribution function is
F(x) = 1- e power (−λx)
The mean of the exponential distribution function
E(X) = 1 / λ
= 1/0.01386
= 72.15
Hence, E(X) = 72.15
The variance of the exponential distribution function
V(X) = 1 / λ ^{2}
= 1/0.01386*0.01386
= 5205.63
V(X) = 5205.63
Probability that the distance is at most 100m
P(X <= 100 ) = F (100)
= 1- e power (−λx)
= 1 - e power (-0.01386*100)
= 1- e power (-1.386)
= 1-0.25007
= 0.749926
Therefore, P(X<=100) = 0.749926
probability that the distance is at most 200m
P ( X<= 200) = F(200)
=1-e power (−λx)
=1-e power (-0.01386*200)
= 1 - e power (-2.772)
= 1-0.06253
= 0.9375
P(X<= 200) = 0.9375
Probability that the distance is between 100 and 200m
P(100<= X <= 200) = F(200) - F(100)
= 0.9375-0.7499
=01876
P(100 <= X <= 200) = 0.1876
Probability that the distance exceeds the mean distance by more than 2 standard deviation.
P( X + P>μ+2σ) = P(X>72.15+2√5205.63)
= P(X > 72.15 +144.3)
P(X>216.45)
= 1-P(X<= 216.45)
1 - (1- e power (-0.01386*216.45)
= e power (-2.9999)
= 0.04979
P( X + P>μ+2σ) = 0.04979
Hence , The probability that the distance is at most 100m is 0.749926 and at most 200 m is 0.9375 between 100 and 200 m is 0.1876 and the probability that distance exceeds the mean distance by more than 2 standard deviations is 0.04979

The volume of the cone is (2/3)π cubic feet. And the radius of the spherical barrier would be 0.8 ft. and the height would be 2r = 2(0.8) = 1.6 ft. The correct option is A.
What is volume?Space occupied by an object in three-dimensional space is called as volume of an object. In simple words, space is taken by object.
Given:
Tobias is constructing barriers to prevent cars from driving on a bike path. He can make conical pylons using the dimensions shown.
He used the same amount of concrete to construct a spherical barrier.
According to the information given in the exercise, the height and the radius of the pylons are the following:
Height h = 2 ft
Radius r = 1 ft
So, the volume of the cone,
= (1/3)πr²h
= (1/3)π(1)²(2)
= (2/3)π cubic feet.
And the volume of the sphere is twice the volume of the cone.
So, the volume of the sphere,
4πr³/3 = 2π/3
2r³ = 1
r³ = 1/2 = 0.5
r = ∛0.5 = 0.8 ft.
Therefore, the radius of the spherical barrier would be 0.8 ft. and the height would be 2r = 2(0.8) = 1.6 ft.
