Explanation:

Angle UOT is vertical to the angle x. This angle combines with 4x and 40 to get a straight angle of 180 degrees

(angle POU) + (angle UOT) + (angle TOS) = 180

4x + x + 40 = 180

5x + 40 = 180

5x = 180-40

5x = 140

x = 140/5

x = 28

Side note: if x = 28, then 4x = 4*28 = 112.

We see that 112+28+40 = 180, which is the sum of the three angles mentioned earlier. Since we got 180, this confirms the answer.

The value of the ratio of tan(90°-R) using the sketch is PR/PQ

From the question, we have the following parameters that can be used in our computation:

The right triangles (see attachment)

From the right triangle, we have the following readings

Opposite of 90 - R = PR

Adjacent of 90 - R = PQ

The ratio of tan(90°-R) is then calculated as

tan(90°-R) = Opposite/Adjacent

So, we have

tan(90°-R) = PR/PQ

Hence, the ratio of tan(90°-R) using the sketch is PR/PQ

This means the gestation period of rhinos is 685.5% longer than the gestation period of cats

The gestation period of rhinos is 487 days

The gestation period of cats is 62 days

The difference between them is:

487 - 62 = 425

Let us find what percentage of 62 is 425

(425/62)*100

= 685.5

This means the gestation period of rhinos is 685.5% longer than the gestation period of cats

The probability that the teacher chooses a girl with glasses is 3/16, and the probability that the teacher chooses a boy with glasses is 1/4.

Let's calculate the probability that the teacher chooses a student with glasses.
a) A girl with glasses: There are 6 girls in the class, and 3 of them wear glasses. There are a total of 16 students (6 girls + 10 boys).
Probability = (Number of girls with glasses) / (Total number of students)
Probability = 3 girls with glasses / 16 total students
Probability = 3/16
b) A boy with glasses: There are 10 boys in the class, and 4 of them wear glasses.
Probability = (Number of boys with glasses) / (Total number of students)
Probability = 4 boys with glasses / 16 total students
Probability = 1/4
So, the probability that the teacher chooses a girl with glasses is 3/16, and the probability that the teacher chooses a boy with glasses is 1/4.

Answer:

∠ABC = 94°

∠BCD = 25°

∠ACB = 43°

Step-by-step explanation:

∠ABD = 133°

Since △ADC is an isosceles triangle where AD = CD, it means that ∠CBD = 133°

We know sum of angles at a point is 360°.

Thus; ∠ABC = 360 - (133 + 133)

∠ABC = 94°

Now, in △BCD, ∠B = 133° and ∠D = 22°

Sum of angles in a triangle = 180°

Thus; ∠BCD = 180 - (133 + 22)

∠BCD = 25°

Since the △ABC is also an isosceles triangle , it means that;

In △ABC, ∠A = ∠C

Thus; ∠ACB = (180 - 94)/2

∠ACB = 86/2

∠ACB = 43°

Without any values of the functions f, g, h, and k, it is not possible to find the equation of each function. The equation of a function can be determined by analyzing the values of the function. Based on the given values, a possible equation can be found and then verified by plotting the points on a graph and seeing if they align with the equation.

It's important to note that the equation can be a linear or exponential equation but it's impossible to determine it without any values.

the balance after 6 years is approximately $926.45.

What is Continuous compounding ?

Continuous compounding is the process of calculating interest and reinvesting it into an account's balance over an infinite number of periods.

We can use the formula for continuous compounding to find the balance after 6 years:

\(F = Pe^{(rt)}\)

where F is the future value, P is the present value, e is the mathematical constant e (approximately 2.71828), r is the annual interest rate, and t is the time in years.

In this problem, P = $550, r = 8.5% = 0.085 (note that we need to use the decimal form of the interest rate), and t = 6 years.

\(F = 550e^{(0.085*6)}\)

F ≈ $926.45

Therefore, the balance after 6 years is approximately $926.45.

Answer:

Step-by-step explanation:

The definite integral of sin^5(x)dx from 0 to pi/2 can be evaluated using the method of substitution.

Let u = sin(x), then du = cos(x)dx

The integral becomes:

∫sin^5(x)dx = ∫u^5du from 0 to sin(π/2)

= (u^6)/6 evaluated at sin(π/2) and 0

= (sin^6(π/2))/6 - 0

= (1^6)/6

= 1/6

So, the definite integral of sin^5(x)dx from 0 to pi/2 is equal to 1/6.

Vector v can be written as the sum of two vector components, \(v_x = -5i\)  and \(v_y = 6j\)

To write vector v as the sum of two vector components, we need to decompose it into two vectors along different directions.

v = -5i + 6j

w = 3i + 4j

We can decompose vector v into two components, one along the x-axis and the other along the y-axis.

Let's denote the component along the x-axis as \(v_x\) and the component along the y-axis as \(v_y.\)

The x-component, \(v_x,\) represents the projection of vector v onto the x-axis and can be found using the dot product of v and the unit vector i:

\(v_x = v . i = (-5i + 6j) . i = -5i . i + 6j . i = -5\)

Similarly, the y-component, \(v_y,\) represents the projection of vector v onto the y-axis and can be found using the dot product of v and the unit vector j:

\(v_y = v . j = (-5i + 6j) . j = -5i . j + 6j . j = 6\)

Now, we can write vector v as the sum of its components:

\(v = v_x + v_y = -5i + 6j\)

So, vector v can be written as the sum of two vector components: -5i along the x-axis and 6j along the y-axis.

The composite function f·g(x) is 4x⁴+24x³.

The given functions are f(x)=x²+6x and g(x)=4x².

We need to find f·g(x).

We know that, f·g(x)=f(x)×g(x)

Here, f·g(x)=(x²+6x)×4x²

= x²×4x²+6x×4x²

= 4x⁴+24x³

Therefore, the composite function f·g(x) is 4x⁴+24x³.
