If f(x) = 3x2 – 4 and g(x) = 2x – 6, what is g(f(2))?
O-16
o -2
O 8
0 10
Answer:
The last option, 10 is correct
Step-by-step explanation:
f(x) = 3x^2 - 4
f(2) = 3(2)^2 - 4
f(2) = 12 - 4
f(2) = 8
g(x) = 2x - 6
g(8) = 2(8) - 6
g(8) = 16 - 6
g(8) = 10
This means that g(f(2)) is equal to 10

write the following as
t = _____
p/q = q/t + 1
Answer:
t = 2q²/p
Step-by-step explanation:
subtract 1 from each side to get:
p/q - 1 = q/t
multiply each side by t/q to get:
(tp/q²) - 1 = 1
add 1 to each side to get:
tp/q² = 2
cross-multiply to get:
tp = 2q²
divide each side by p to get:
t = 2q²/p
2*3*5*11+x*2 = 662
What's x?
Answer:
x = 166
Step-by-step explanation:
2 * 3 * 5 * 11 + (x * 2) =
6 * 5 * 11 + (x * 2) =
30 * 11 + (x * 2) =
330 + (x * 2) =
330 + (166 * 2) =
= 662
So, the answer is 166.

The difference of twice a number and five is three. Find the number
Answer:
The number is 4.
The step describe to solve the problem is: add five and then multiply by
Step-by-step explanation:
Let the number be x.
As per the given condition as:
The difference of twice a number and five is three.
"Twice a number" means
"difference of twice a number and five" means
therefore, the translation of the given word problem to an equation is:
Now, solve the equation :
Addition Property of equality states that you add the same number to both sides of an equation.
Add 5 to both sides of an equation we get;
2x-5+5=3+5
Simplify:
2x = 8
Multiplication property of equality states that you multiply the same number to both sides of an equation.
Multiply by both sides we get;
Simplify:
x = 4
The steps which describe to solve the problem is: add five and then multiply by
Therefore, the number x = 4

A movie theater sells morning tickets (m) for $4 and regular tickets (e) for $6. During one week, the theater earned $6000. The theater sold 890 more regular tickets than morning tickets.
Write a system of liner equation to represent this situation. (Solve by using Systems by Substitution)
Answer:
Step-by-step explanation:
Answer:
m = 66 & e = 956
Step-by-step explanation:
Create your equations:
$4m + $6e = $6000
m + 890 = e
Substitute/solve for morning tickets:
$4m + $6e = $6000 <-- m + 890 = e
$4m + $6(m + 890) = $6000
$4m + $6m + $5340 = $6000
$10m = $6000 - $5340
m = $660/$10
m = 66 morning tickets
Solve for Regular tickets:
m + 890 = e <--- m = 66
66 + 890 = 956
e = 956 regular tickets
Double check work:
$4m + $6e = $6000
$4(66) + $6(956) = $6000

When looking at triangles it's always important to remember what the ratios are to parts of triangles. In the case of this triangle let's give the value 24 the variable of E. In every scenario in which Y is positioned above 24 or E, the answer is always E/2=y, or 24/2=y ---> 12.
y / 24 = 12 / 12 + 18
y / 24 = 12 / 30
y / 24 = 2 × 6 / 5 × 6
y / 24 = 2 / 5
y = 24 × 2 / 5
y = 48 / 5
y = 96 / 10
y = 9.6

Lila is making 1/4 of a recipe for a bake sale. The original recipe calls for 2/3 cups of sugar. How much sugar does Lila need to
complete her recipe?
Answer:
Step-by-step explanation:
1/4 of 2/3 is just (1/4) / (2/3) or (1/4)(3/2)
1/4 * 3/2= 3/8
She needs to use 3/8 of a cup
The sugar needed by Lila to make 1 / 4 of a recipe is 1 / 6 of the total sugar needed to complete her recipe.
What is fraction?A fraction is a percentage of a whole. This entire sentence could be referring to a single location or a collection of locations. The English word "fraction" originates from the Latin word "fraction," which means "to break." As the first society to comprehend fractions, the Egyptians used fractions to solve a number of mathematical problems, including the distribution of food and resources and the absence of a metal currency.
Given:
The sugar quantity in the original recipe = 2 / 3
If Lila is making 1 / 4 of a recipe, so she needs 1/ 4 of the total sugar in the recipe,
The sugar needed by Lila = 1 / 4 of 2 / 3
The sugar needed by Lila = 1 / 4 × 2 / 3,
The sugar needed by Lila = 1 / 6 of the total sugar needed in the recipe.
Therefore, the sugar needed by Lila to make 1 / 4 of a recipe is 1 / 6 of the total sugar needed in the recipe.

Technology required. ABCD is a rectangle. Find the length of AC and the measures of a
and e.
Help pleaseee
Answer:
AC = 12.4
Theta = 75.96 degrees
Alpha = 14.04 degrees
Step-by-step explanation:
Mathematically, the angle at each edge of the rectangle is 90 degrees
So, we can see a right triangle ABC
Where AC is its hypotenuse
Mathematically, the square of the hypotenuse equals the sum of the squares of the two other sides
That will be;
3^2 + 12^2 = 9 + 144 = 153
AC = √153
AC = 12.4
We need to use the appropriate trigonometric ratio to get the value of alpha and theta
For theta;
Its opposite side is 3 while its adjacent is 12
The trigonometric ratio to use is the tan
so;
tan theta= 3/12
tan theta = 1/4
theta = tan^-1 0.25
theta = 14.04
Now for alpha, since we have a right triangle
theta will be 90-14.04
theta = 75.96
The measure of AC to the nearest hundredth is 12.37
SOH CAH TOA identityFrom the given figure, we have the following parameters
Using the theorem;
tan a = 12/3
tan a = 4
a = 75.96
theta = 90 - 75.96
theta = 14.03
For the length of AC, we will use the Pythagoras theorem
AC = √3² + 12²
AC = √9+144
AC = 12.37
Hence the measure of AC to the nearest hundredth is 12.37

The function f(x)=Acosh(Cx)+Bsinh(Cx). I need help determining the value of constant C>0 when the second derivative f''(x)=25(f(x)).
Answer:
C = 5.
Step-by-step explanation:
First, you need to remember that:
For the function:
h(x) = Sinh(k*x)
We have:
h'(x) = k*Cosh(k*x)
and for the Cosh function:
g(x) = Cosh(k*x)
g'(x) = k*Cosh(k*x).
Now let's go to our problem:
We have f(x) = A*cosh(C*x) + B*Sinh(C*x)
We want to find the value of C such that:
f''(x) = 25*f(x)
So let's derive f(x):
f'(x) = A*C*Sinh(C*x) + B*C*Cosh(C*x)
and again:
f''(x) = A*C*C*Cosh(C*x) + B*C*C*Sinh(C*x)
f''(x) = C^2*(A*cosh(C*x) + B*Sinh(C*x)) = C^2*f(x)
And we wanted to get:
f''(x) = 25*f(x) = C^2*f(x)
then:
25 = C^2
√25 = C
And because we know that C > 0, we take the positive solution of the square root, then:
C = 5
Find the derivative of f(x) = -4x2 + 11x at x = 10.
a) 19.5
b) -69
c) 30
d) -300
Answer:
-69 (Answer b)
Step-by-step explanation:
Apply the power rule for differentiation:
(d/dx){-4x^2 + 11x} = -8x + 11
Now substute 10 for x:
f '(x) = -8(10) + 11 = -80 + 11 = -69 (Answer b)
Answer:
b
Step-by-step explanation:
Using the power rule to differentiate each term
Given
f(x) = - 4x² + 11x , then
f'(x) = - 8x + 11
At x = 10
f'(10) = - 8(10) + 11 = - 80 + 11 = - 69 → b
