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

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

Step-by-step explanation:

Pythagorean Theorem is a^2 + b^2 =c^2

a= 9 , b= 15, c= x

9^2 + 15^2 = c^2

[tex]\sqrt{306}[/tex]= c^2

c= 17.493 or 17.5 rounded to the nearest tenth

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:

(i) Rational numbers - A number which can be expressed as fraction, ratio or percentage is called as rational number

(ii)Irrational numbers - A number which is not rational, (i.e) cannot be expressed as a ratio or percentage is called as irrational number.

Since there are no common numbers in rational and irrational, they cannot be expressed as "G" option.

Real numbers are formed by the union of rational and irrational numbers.

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

Answer:

11/20

3/5

7/10

13/20

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

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:

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
