Does Anyone Know This? I Can't Seem To Figure This One Out At All.

Answers

Answer 1

Answer:

a = 5, b = -1

Step-by-step explanation:

Simplify the left side.

Multiply both numerator and denominator by the conjugate of the denominator:

(√3 - 1)/(√3 + 1) = (√3 - 1)(√3 - 1)/(√3 - 1)(√3 + 1) =(√3² - 2√3 + 1)/(3 - 1) =(10 - 2√3)/2 = 5 - √3

Compare this to the right side to get:

5 - √3 = a + b√3a = 5, b = -1

Two streets form an intersection. C and D are supplementary
angles. If the measure of C is 140° and the measure of D is
two times the value of x, what is the value of x?

Answers

Answer:

20degrees

Step-by-step explanation:

The sum of angle C and D is 180 degrees since they are supplementary

Given

m<C = 140 degrees

m<D = 2x

Taking the sum and equating to 180

140 + 2x = 180

2x = 180-140

2x = 40

x = 40/2

x = 20 degrees

Hence the value of x is 20degrees

Answers

Answer:

5.4

Step-by-step explanation:

To find the distance between two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], plug them into the following equation:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(-3-(-8))^2+(-4-(-6))^2}[/tex]

Two negatives make a positive

[tex]d=\sqrt{(-3+8)^2+(-4+6)^2}\\d=\sqrt{(5)^2+(2)^2}\\d=\sqrt{25+4}\\d=\sqrt{29}\\d=5.4[/tex]

Therefore, the distance between the two points rounded to the nearest tenth is 5.4.

Write a function in terms of t that represents the situation.
Sales of $10,000 increase by 65% each year.
y =
13

Answers

Answer:

A function in terms of t that represents the situation is:

[tex]\:y\:=\:10,000\left(1.65\right)^t[/tex]

Step-by-step explanation:

We know that the exponential growth function is of the form

[tex]y\:=\:a\:\left(1\:+\:r\right)^t[/tex]

Here:

a = initial value r = growth rate  t = number of time intervals that have passed

As the sales of $10,000 represent an initial condition. Thus,  

a = 10,000

Given that sales are increased by 65% every year.

r = 65% = 0.65

now substituting a = 10,000 and r = 0.65 in the function

[tex]y\:=\:10,000\left(1\:+\:0.65\right)^t[/tex]

[tex]\:y\:=\:10,000\left(1.65\right)^t[/tex]

Therefore, a function in terms of t that represents the situation is:

[tex]\:y\:=\:10,000\left(1.65\right)^t[/tex]

Step-by-step explanation:

one of these students is chosen at random. what is the probability of picking a student who scored above 65​

Answers

Answer:

7/18

Step-by-step explanation:

7 students received a score greater than 65, out of a total of 18 students

The probability of picking a student who scored above 65 is 1/3 when one of these students is chosen at random.

To calculate the probability of picking a student who scored above 65, we need to determine the number of students who scored above 65 and divide it by the total number of students.

Looking at the given marks:

46, 65, 54, 57, 62, 73, 73, 47, 69, 48, 63, 68, 55, 48, 58, 71, 76, 70

We can see that the marks above 65 are: 73, 73, 69, 68, 76, 70 (a total of 6 marks).

Now, let's calculate the probability:

Probability = Number of favorable outcomes / Total number of outcomes

Number of favorable outcomes (students who scored above 65) = 6

Total number of outcomes (total number of students) = 18

Probability = 6 / 18

Simplifying the fraction:

Probability = 1 / 3

Therefore, the probability of picking a student who scored above 65 is 1/3.

Sum of two numbers is 29 and one number exceeds another by 5. Find the numbers.​

Answers

Answer:

24 is the answer

Step-by-step explanation:

* 29-5=24

* 24+5=29

First number = 12
Second number = 17

x + x + 5 = 29
2x + 5 = 29
2x = 24
x = 12

So, one number is 12 and the other one is 12 + 5 = 17
17 is greater than 12 by 5
12 + 17 = 29

Find the slope and the y-intercept of the graph of y+1=4/3x.
What is the slope and the y-intercept?

Answers

Answer:

Slope = 4/3x; y-intercept = -1

Step-by-step explanation:

y + 1 = 4/3x

You have to write this equation in slope-intercept form (solve for y) if you want to find the slope and y-intercept

y + 1 = 4/3x

Subtract one from both sides

y + 1 - 1 = 4/3x - 1

y = 4/3x - 1

Now that we have the equation, you can now find the slope and y-intercept

y = mx + b; m is the slope and b is the y-intercept

So for y = 4/3x - 1, the slope is 4/3x and the y-intercept is -1
