Answer:
Surface area of cylinder = 24π
Step-by-step explanation:
Given:
Base diameter = 4 yd
So Radius = 4 / 2 = 2 yd
Height = 4 yd
Find:
Surface area of cylinder
Computation:
Surface area of cylinder = 2πr(h+r)
Surface area of cylinder = 2π(2)(4+2)
Surface area of cylinder = 2π(2)(6)
Surface area of cylinder = 24π

Solve the following equation for all values of x. Be sure to check for extraneous roots.
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
First, let's multiply both sides by [tex]\sqrt{x+11}[/tex]. If we do this, we would have:
[tex]x-1=\frac{1}{\sqrt{x+11}}\cdot\sqrt{x+11}[/tex]
The [tex]\sqrt{x+11}[/tex] would cancel out and we would be left with:
[tex]x-1=1[/tex]
If we add 1 on both sides, we would get:
[tex]x=2[/tex]

Write the expressions in standard form. SHOW ALL STEPS! The sum of 9t – 13 and the opposite of 9t.
Answer:
-13
Step-by-step explanation:
Opposite of 9t = -9t
Taking the sum of 9t - 13 and -9t
Sum = 9t - 13 + (-9t)
Sum = 9t - 13 - 9t
Sum = 9t-9t - 13
Sum = -13
Hence the expression in standard form is -13
Given that x and y are positive integers and (x*2)+x(2^2)+(y*2^3)+(y*2^4)=42, what is the value of xy? PLEASE HELP!!!!!!
Note: Answer is not x=0, y=7 or y=0, x=7
Answer:
x = 3, y = 1
Step-by-step explanation:
If your question is this: 2x + 4x + 8y + 16y = 42
6x + 24y = 42
3x + 12y = 21
For x and y are positive integers, there is only 1 set of x = 3 and y = 1 is the solution (because x = 7 and y = 0 is excluded)
check: 6 + 12 + 8 + 16 = 42

F(n)=
F(9)=
Step-by-step explanation:
You can put this solution on YOUR website!
The total of Jenny's 5 tests = 375
If she wants an average of 77 then
her 6 tests must total 6 x 77 = 462
462 - 375 = 87 which is what Jenny
must score on the sixth test for an
average of 77.
:-)
Answer:
79
Step-by-step explanation:
Sum of 4 test for Average of 82 must be 82 x 4 which is 328.
Subtract previous 3 scores from 328:
328 - (98 + 83 + 68)
328 - 249 = 79
She needs a 79

Given that ℓ1∥ℓ2 and the measure of ∠c = 44°, find the measures of angles a and b.
m∠a =
°
m∠b =
°
Answer:
<a = 44 degrees
<b = 136degrees
Step-by-step explanation:
From the given diagram;
<a = <c (alternate interior angle)
Since <c = 44 degrees, hence <a = 44 degrees
Also the sum of a and b is supplementary hence;
a + b = 180
44 + b = 180
b = 180 - 44
b = 136degrees
Hence m<b =136degrees
A national park is a rectangle that is 33 miles wide and 56 miles long, How long is a
diagonal road through the park?
Answer:
this would be a right triangle with the legs being 8 miles and 6 miles. using the Pythagorean theorem, the hypotenuse would be 10 miles long. therefore, he would be walking a total of four miles less if he walked diagonally.

Melanie invested $8,600 in an account paying an interest rate of 2\tfrac{7}{8}2 8 7 % compounded monthly. Oliver invested $8,600 in an account paying an interest rate of 2\tfrac{3}{4}2 4 3 % compounded daily. After 10 years, how much more money would Melanie have in her account than Oliver, to the nearest dollar?
Answer:
$139
Step-by-step explanation:
The formula for compound interest =
A = P(1 + r/n)^nt
Where
P = Principal
r = Interest rate
n = Compounding frequency
t = time in years
A = Amount after t years
For Melanie
Melanie invested $8,600 in an account paying an interest rate of 2 7/8% compounded monthly.
Rate = 2 7/8% = 23/8% = 2.875%
Time = 10 years
n = monthly = 12
First, convert R percent to r a decimal
r = R/100
r = 2.875%/100
r = 0.02875 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 8,600.00(1 + 0.02875/12)^(12)(10
A = 8,600.00(1 + 0.002395833)^(120)
A = $11,460.64
For Oliver
Oliver invested $8,600 in an account paying an interest rate of 2 3/4 % compounded daily.
Rate = 2 3/4% = 11/4% = 2.75%
Time = 10 years
n = daily = 360 days
First, convert R percent to r a decimal
r = R/100
r = 1.375%/100
r = 0.01375 per year,
Then, solve our equation for A
First, convert R percent to r a decimal
r = R/100
r = 2.75%/100
r = 0.0275 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 8,600.00(1 + 0.0275/360)^(360)(10)
A = 8,600.00(1 + 7.6389E-5)^(3600)
A = $11,322.05
After 10 years, how much more money would Melanie have in her account than Oliver, to the nearest dollar?
This is calculated as
$11,460.64 - $11,322.05
=$ 138.59
Approximately to the nearest dollar = $139

What is the first step Anika made from the original equation.
Answer:
She factored out a 4 from the equation.
Step-by-step explanation:
So our original equation is 12x + 4 = 20x - 12
Anika's first steep of her equation is 3x + 1 = 5x - 3
We know that the terms were not moved around, so the first step was likely multiplication or division.
We also see that a 4 has been factored out of the entire equation, like this:
12x + 4 = 20x - 12
4(3x + 4) = 4(5x - 3)
And these 4's cancel each other out.
So, I conclude that Anika's first step was dividing the entire equation by 4 or factoring out a 4 from the equation.

Which equation can be used to solve for c? Triangle A B C is shown. Angle A C B is 90 degrees and angle A B C is 35 degrees. The length of C B is 5 inches, the length of A C is b, and the length of B A is c.
Answer:
c = 5/Cos 35
Step-by-step explanation:
We are given the following
m<ACB = 90degrees
m<ABC = 35degrees
The side opposite to m<ABC is AC
BA = hypotenuse
CB = adjacent = 5inches
Required
Equation to solve BA which is c
Using the Pythagoras theorem;
Cos theta = Adjacent/Hypotenuse
Cos m<ABC = CB/BA
Cos m<ABC = 5/c
c = 5/cosm<ABC
c = 5/Cos 35
Hence the equation that can be used to solve for c is c = 5/Cos 35

If x-1= k and k=3, what is the value of x
3
Answer:
x-1/3 = k where k=3
We must be happy enough to find the value of only one valuable here, that is, x.
therefore, x-1/3=3
To find what is x-1, all we need to do is,
Take the denominator of the fraction to the answer (3)and multiply them. (that's how you'll find the values in the numerator)
So, you'll get,
x-1=3*3
x-1=9
To find the value of x,
The other number (-1) should be taken to the answer (9)
(Remember that the sign changes when the number crosses the equals sign)
therefore,
x= 9 + 1 (-1 will turn to +1 on crossing the equal sign)
Therefore , by addition, normally,
you'll get x=10
Hope this helps:)
Which equation represents a nonlinear function? y=−85x+19.4 y = − − 8 5 x + 19.4 y=−12x2−7 y = − − 1 2 x 2 − − 7 y=x4+x y = x 4 + x y=32−4x
Answer:
The answer is below
Step-by-step explanation:
The options are not clear. I would solve a similar question.
A linear function is a function in the form:
y = mx + b; where y and x are variables, m is the slope and b is the y intercept.
From the options:
a) y = 3x³
Since the equation is not in the form of y = mx + b, hence it is not a linear function. It is a nonlinear function.
b) 3x + 2y = 10
2y = -3x + 10
The equation is in the form of y = mx + b, hence it is a linear function.
c) y = 15.3
The equation is in the form of y = mx + b, hence it is a linear function.
d) y = (1/4)x - 2
The equation is in the form of y = mx + b, hence it is a linear function.

Which box and whisker plot best represents these data?
EXTRA POINTS -- Find the measure of the angles marked a, b, c, etc. in each diagram below
Which graph below shows the rule: output = 5 times input?
Given:
Output = 5 times input
To find:
The graph for the given statement.
Solution:
We know that, y-axis represents the output and x-axis represents the input.
Let y be the output and x be the input. Then the given statement can be written as
[tex]y=5x[/tex]
Here, the slope of the line is 5 because the value of [tex]m[/tex] is 5 on comparing the equation with [tex]y=mx+b[/tex].
It means the line is steeper because the vertical change is greater than the horizontal change.
Therefore, the correct option is A.
