Answer:
Miguel needs 1,369/9 square inch of carpeting
Step-by-step explanation:
Here, we want to know the size of carpeting needed to cover the floor
What we have to do here is to find the area of the bedroom floor
Mathematically, we have this as the product of the dimensions of the floor;
This will give;
12 1/3 inches * 9 1/4 inches
= 37/3 * 37/3 = 1,369/9 square inches

Why is “h” negative in math
Answer:
Just remember that when it comes to vertex form and parabola transformations a negative h means shift right and positive h left. We anumberd to the number lgraphbitself itself having negative integers on left and positive on right and I can see why this throws people off.
Step-by-step explanation:
can i get brainlist brainly deleted all my answers for no reason
Answer:
he parameter h is the extremal point of the quadratic. The extremum happens when x=h, when the function (x−h)2 is minimized (or −(x−h)2 maximized). So the reason for the minus sign is because x=h is equivalent to x−h=0.

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
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

Can somebody please help me out:))
Answer:
50ft
Step-by-step explanation:
Hi,
Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.
One of the legs is equal to 40 feet
So, tan(b) = 40/x
tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)
0.8 = 40/x
0.8x = 40
x = 50ft

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

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

A group of 8 friends shared all the sports cards in 3 packages. Each package contained 1,400 sports cards. Each friend received the same number of sports cards.
How many sports cards did each friend receive?
Answer:
i think it is 525 cards.
Step-by-step explanation:
because 3 packages = 1400 sport cards
3 x 1400 = 4200
4200 divided by 8 = 525 cards.
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

Answer:
11/20

Step-by-step explanation:
A rational number is a number that can be derived by dividing 2 whole numbers
1/2 = 0.5 0r 50%
3/4 = 0.75 75%
Between 50% and 75% are 51 - 74 which can be expressed as rational numbers
3/5 = 0.6
7/10 = 0.7
11/20 = 0.55
13/20 = 0.65
