Help pleaseee

Answers

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 identity

From 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

A truck can be rented from Company A for ​$90 a day plus ​$0.50 per mile. Company B charges ​$40 a day plus ​$0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

Answers

Tthe number of miles in a day at which the rental costs for Company A and Company B are the same is    500 miles

The truck is driven X miles per day

Charges of company A will be = 90+0.5x

Charges of company B will be =40+0.60x

We need to find the value of X when charges of both companies are same

90+0.5X= 40+0.60x

   90-40 = 0.60x-0,50x

            50 = 0.10x

                    50/0.10= X

                             X= 500

The charges of both companies will be same if truck is driven 500 miles per day

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

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)).

Answers

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

Answers

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
