Find the indicated angle using trigonometry

Answers

The measure of indicated angle in the given triangle is 71.035°.

What are trigonometric ratios?

The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

In the given right angled triangle, hypotenuse side is 74 units and the two legs of triangle are 70 units and 24 units.

Let the unknown angle be x.

We know that, tanθ =Perpendicular/Base

Now, tan x= 70/24

tan x= 2.91

x =71.035°

So, one of the angle in the triangle is 71.035°.

Therefore, the measure of unknown angle is 71.035° in the given triangle.

The perpendicular equation is y = -1/3x + 10 Option A

How to find perpendicular of an equation?

You can find this by first realizing that perpendicular lines have opposite and reciprocal slopes. So since it starts at 3 we flip it and make it a negative and the new slope is -1/3.

Now we can use that and the point to get the y intercept using slope intercept form.

y = mx + c

m = gradient of the line

c = y -intercept

8 = (-1/3)(6) + c

8 = -2 + c

10 = c

And now we can use our new slope and new intercept to model the equation. y = -1/3x + 10

Zachary purchased a computer for $1,400 on a payment plan. Two months after he purchased the computer his balance was $1,100. Four months after he purchased the computer, his balance was $800. What is an equation that models the balance y after x months?
The equation
models the balance y after x months:

Answers

Answer:

Zachary pays $150 per month for his computer

Step-by-step explanation:

after 2 months:

2x + 1100y = 1400..... equation 1

after 4 months:

4x + 800y = 1400...... equation 2

we can either multiply equation 1 by 2 or we can divide equation 2 by 2, the purpose is simply to get the x values equal so it can be eliminated from the equation.

dividing equation 2 by 2:

2x + 400y = 700 ...... equation 3

Now equation 1 minus equation 3:

0x + 700y = 700

700y = 700

y = 700/700

y = 1

substituting y=1 into equation 3

2x + 400(1) = 700

2x = 700 - 400

2x = 300

x = 300/2

x= 150

Therefore it is concluded that Zachary has a payment plan where he pays $150 each month for the computer

Exponential functions

An exponential function is a Mathematical function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

An exponential function is defined by the formula f(x) = ax, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.

The exponential function is an important mathematical function which is of the form

f(x) = ax

Where a>0 and a is not equal to 1.

x is any real number.

If the variable is negative, the function is undefined for -1 < x < 1.

Here,

“x” is a variable

“a” is a constant, which is the base of the function.

Answers

The lower limit of the confidence interval is 51%, which is above 55%, so the Republican should expect to win.

What does confidence interval mean?

Your estimate's mean plus and minus the range of that estimate's fluctuation is called a confidence interval.

                       If you repeat your test, you can expect your estimate to fall between these numbers with a reasonable degree of certainty. In statistics, confidence is another word for probability.

A confidence interval of proportions has two bounds, a lower bound and an upper bound.

These bounds depend on the sample proportion and the margin of error.

The lower bound is the sample proportion subtracted by the margin of error.

The upper bound is the margin of error added to the sample proportion.

In this problem, we have that:

Sample proportion 53%

Margin of error 2%

53 - 2 = 51%

53 + 2 = 55%

Hence, the lower limit of the confidence interval is 51%, which is above 55%, so the Republican should expect to win.

What is the linear equation?

A linear equation is an equation of a straight line, written in the form y = mx + b. In this equation, m is the slope of the line and b is the y-intercept. Linear equations are used to describe relationships between variables, and they can also be used to solve problems with multiple unknowns. For example, if you know the slope of a line and the y-intercept, you can use a linear equation to calculate the x-intercept. Linear equations can also be used to model real-world situations, such as calculating the cost of a product or the amount of money saved over a period of time.

We have given:

the value of 35x + 10y, When x=8 and y=5.

Using substitution, substitute the given values of x and y.

35x + 10y

y^2 - 6y + 9 - y + 3 +3y - 8 = 0

y^2 - 4y + 4 = 0

Find the number of years it takes for his investment money to be doubled from his
original investment. ​

Answers

Mr. Ramli's investment in the small entrepreneurship will be doubled in 8 year.

Explain the term rate of change?The term "rate of change" (ROC) describes the rate which something evolves over time. Thus, it is not the amount of specific changes themselves but rather the acceleration or slowdown of changes (i.e., the rate). Rate of change is a tool used in finance to comprehend price returns and spot trend momentum.

For the stated equation-

rate of increase is given as-

dy/dx = 2(x + 121) < - rate of the change

dy = 2(x + 121)dx

Integrating;

∫dy = ∫2(x + 121)dx

y = x² + 242x + C

At x = 0, y(0) = 0 Thus,

(0)² + 242(0) + C = 2000

C = 2000

Now, y = x² + 242x + 2000

Calculate 't' to get the y(t) = 40,000 (double the amount)

4000 = x² + 242x + 2000

x² + 242x - 2000 = 0
