Which of the following expressions are equivalent to −5.93+(−8.62)+5.93?
Answer:
A, B, C, DStep-by-step explanation:
−5.93 + (−8.62) + 5.93 =−5.93 - (8.62 - 5.93) = B−(5.93 + 8.62) + 5.93 = C−5.93 −8.62 - (- 5.93) = D-8.62 AAll options Except E
Because
From question
The expression yields -8.62 after 5.93 gets cancelled outBut in E
-5.93-(8.62+5.93)Results one -5.93 more so 5.93 doesn't get cancelled out

(2x + y)2 – (3x – 2y)2 + (x – 4y)(x + 4y
11
Answer:
Step-by-step explanation:
(a+ b)² = a² + b² + 2ab
(2x + y)² = (2x)² + y² + 2*2x *y
= 4x² + y² + 4xy
(a- b)² = a² + b² - 2ab
(3x - 2y)² = (3x)² + (2y)² - 2*3x *2y
= 9x² + 4y² - 12xy
(a - b)(a +b) = a² - b²
(x - 4y(x + 4y) = x² - (4y)²
= x² - 16y²
(2x + y)² - (3x - 2y)² + (x - 4y)(x +4y)
= 4x² + y² + 4xy - (9x² + 4y² - 12xy) + x² - 16y²
= 4x² + y² + 4xy - 9x² - 4y² + 12xy + x² - 16y²
= 4x² - 9x² + x² + y² - 4y² - 16y²+ 4xy + 12xy
= -4x² - 19y² + 16xy
The radius of a circle is changing at the rate of 1/π inches per second. At what rate, in square inches per second, is the circle’s area changing when the radius is 5 inches?
Answer:
10 square inches per second.
Step-by-step explanation:
The radius of the circle is given by the equation:
r(t) = (1/π in/s)*t
Where time in seconds.
Remember that the area of a circle of radius R is written as:
A = π*R^2
Then the area of our circle will be:
A(t) = π*( (1/π in/s)*t)^2 = π*(1/π in/s)^2*(t)^2
Now we want to find the rate of change (the first derivation of the area) when the radius is equal to 5 inches.
Then the first thing we need to do is find the value of t such that the radius is equal to 5 inches.
r(t) = 5 in = (1/ in/s)*t
5in*(π s/in) = t
5*π s = t
So the radius will be equal to 5 inches after 5*π seconds, let's remember that.
Now let's find the first derivate of A(t)
dA(t)/dt = A'(t) = 2*(π*(1/π in/s)^2*t = (2*π*t)*(1/π in/s)^2
Now we need to evaluate this in the time such that the radius is equal to 5 inches, we will get:
A'(5*π s) = (2*π*5*π s)*((1/π in/s)^2
= (10*π^2 s)*(1/π^2 in^2/s^2) = 10 in^2/s
The rate of change is 10 square inches per second.
Christie's Auction sold a painting for
$24,500. It charges all buyers a 15%
premium of the final bid price. How much
did the bidder pay Christie's?
The price that bidder pays to Christie's is $2130.4.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
And to convert a fraction or a decimal into percentage, they are multiplied by 100.
Given that,
The price for which painting is sold is $24,500.
The percentage of premium price of the final bid is 15%.
Suppose the price paid by the bidder be x.
Then, as per the question the following equation can be written for the price of painting,
x + 15% of x = 24500
=> x + (15/100)x = 24500
=> 115x/100 = 24500
=> x = (24500 × 100) ÷ 115
=> x = 2130.43
Hence, the amount paid to Christie's is $2130.4.

A jacket is priced $35.99, and is on sale for 25% off. What is the sale price of the jacket?
Answer:
The answer is $27
Step-by-step explanation:
This answer is pretty simple. All you have to do is multiply 35.99 x 0.25. This will get you the numeral 8.99... That is the discount. Next you will take the total amount and subtract it with the discount.
35.99 - 8.99 = 27
That is the sale price of the jacket.

-Nitroid444The owner of the Texans football team wants to paint their red, white, and blue logo on the side of a building at their training facility. However, the existing paint, which would comprise the background for the logo, is beginning to deteriorate. The owner is considering re-painting the building with a special weatherproof paint prior to adding the logo. If the special background paint costs $1.25 per square foot, how much money will the owner have to spend on the paint for the background
Answer:
$393.75
Step-by-step explanation:
cost of special background paint = $1.25 per square foot
Area of background = area of triangle + area of rectangle
= 1/2 ( b*h) + L * B
= 1/2 ( 5 * 6 ) + 5 * 4 = 15 + 20 = 35 yd^2
Given that 1 yd^2 = 9 ft^2
35 yd^2 = ( 9 * 35 ) ft^2
Hence area of background = 315 ft^2
Cost = 315 * 1.25 = $393.75
Find the simple interest on the following amounts:
a K4000 invested at 6% p.a. for 4 years
b K23 000 invested at 6.5% p.a. for 8 years
K580 borrowed at 5% p.a. for 9 months
inte
с
500
Answer:
a. Simple interest = K960
b. Simple interest = K11,960
c. Simple interest = K261
Step-by-step explanation:
Given the following data;
a. Principal = K4000
Interest rate = 6%
Time = 4 years
To find the simple interest;
Mathematically, simple interest is calculated using this formula;
[tex] S.I = \frac {PRT}{100} [/tex]
Where;
S.I is simple interest.
P is the principal.
R is the interest rate.
T is the time.
Substituting into the equation, we have;
[tex] S.I = \frac {4000*6*4}{100} [/tex]
[tex] S.I = \frac {4000*6*4}{100} [/tex]
[tex] S.I = \frac {96000}{100} [/tex]
S.I = K960
b. Principal = K23 000
Interest rate = 6.5%
Time = 8 years
To find the simple interest;
[tex] S.I = \frac {PRT}{100} [/tex]
Substituting into the formula, we have;
[tex] S.I = \frac {23000*6.5*8}{100} [/tex]
[tex] S.I = \frac {1196000}{100} [/tex]
S.I = K11,960
c. Principal = K580
Interest rate = 5%
Time = 9 months
To find the simple interest;
[tex] S.I = \frac {580*5*9}{100} [/tex]
[tex] S.I = \frac {26100}{100} [/tex]
S.I = K261

Enter the amplitude of the function. f(x)=5cosx
Amplitude of f(x)=5cosx
= 5
what's an amplitude example?The amplitude of a periodic variable is a measure of its change in a single period. The amplitude of a non-periodic signal is its magnitude as compared with a reference value. there are numerous definitions of amplitude, which can be all functions of the magnitude of the differences between the variable's extreme values.
It refers to most displacement from the equilibrium that an object in periodic motion show. as an example, a pendulum swings through its equilibrium point (straight down), and then swings to a maximum distance away from the center.

The cost of bottles of vitamins varies
directly with the number of vitamin
tablets in a bottle. A bottle of 50 vitamin
tablets costs $12. What is the cost in
dollars of a bottle of 75 vitamin tablets?
Answer:
find cost of one vitamin tablet first
50/12 = 4.2
therefore $4.2 is the cost for one tablet
now to find the cost of 75 vitamin tablets we just need to multiply the cost of one tablet with 75.
75*4.2=315
therefore the cost of a bottle of 75 vitamin tablets is $315

height, in inches, of these players?
A)76
B)72
C)71
D)70
Answer:
C) 71
Step-by-step explanation:
To find the mean you must first add all the numbers:
68 + 70 + 76 + 71 + 70 = 355.
After that you divide the number you got by how many numbers are in the set.
There are five players so we divide the number by 5
355/5 = 71
Therefore, it is 71.
