pls help trigonometry is confusing to me :(

Answers

My first tip would be to label your triangles.

If you find our reference angle and go across, that would be our opposite side, so x is the opposite side.

The line with both the reference angle and the right angle would be our adjacent side, so 40 would be the adjecent side.

If you find the right angle and go across, that would be our hypotenuse.

//

In this problem, we are given an angle and the adjacent side and we are looking for the opposite side, so that means that we would be using our tangent ratio.

[tex]tan = \frac{opp}{adj} = \frac{x}{40} [/tex]

[tex] \tan(43) = \frac{x}{40} [/tex]

if the thing you are looking for is on the numerator, we would have to multiply. If the thing you're looking for is in the denominator, you would have to divide.

Since x is on the numerator, we would have to multiply.

[tex]x = 40 \tan(43 ) [/tex]

[tex]x = 37.3006034455[/tex]

[tex]x = 37.30[/tex]

Which table represents a quadratic function?

Answers

Answer:

D

Step-by-step explanation:

A table of values can be generated from a quadratic function by substituting the x-values and calculating the values for f(x). When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.

Write the equation of the line in slope-intercept form with slope = 1/4 and point (-8, 6)

Answers

Step-by-step explanation:

This is the standard linear equation:

[tex]y=mx+b[/tex]

[tex]m[/tex] represents slope and [tex]b[/tex] represents the y-intercept. In a finished equation, [tex]x[/tex] and [tex]y[/tex] are left as variables. [tex]x[/tex] and [tex]y[/tex] represent any given point in the function. In this case, one of the given coordinates is [tex](-8, 6)[/tex], and we can use this by using [tex]-8[/tex] as [tex]x[/tex] and [tex]6[/tex] as [tex]y[/tex]. After plugging in known variable, the equation becomes this:

[tex]6 = \frac{1}{4} ( - 8) + b[/tex]

This simplifies to:

[tex]6 = - 2 + b[/tex]

Then to:

[tex]4=b[/tex].

After plugging in slope and y-intercept, the finished equation is:

[tex]y = \frac{1}{4} x + 4[/tex]

25, 0, -18, 5, -12

-12, 25, 5, 0, -18

5, -18, 25, -12, 0

Step-by-step explanation:

The only values you need to use here are 0, 5, 25, -12, and -18.

I started with the bottom right box because the far right column only had one empty box. From the set of values I stated above, that column already had each of those numbers except for 0, so 0 would go in the bottom right box.

Another way to think about it is each row or column must have a 5 and a 25 to make 30, and a -12 and a -18 to make -30. Those two numbers cancel each other out to make 0, and then each row/column will include a 0 value which obviously wouldn't effect that balance. So the whole row/column will come out to be 0.

After figuring out that first bottom right box, go to the next row/column with only one empty box left (this happened to be the very bottom row), and use the same strategy to fill in the missing value.

Continue finding the next row/column with only one empty box left and figure out its missing value until you've completed the whole box.

The table shows data for a car stopping on a wet road. Stopping distance formula [tex]d(v)=\frac{2.15v^{2} }{64.4f}[/tex]

Determine the value of f, rounded to the nearest hundredth.

Answers

Answer:

0.35

the next one is d(v) = 2.15v^2 / 22.54

Step-by-step explanation:

i just did this assignment. also thanks to the answer above me :)

We have that the value of f, rounded to the nearest hundredth.

f_1=0.02

f_2=0.009

f_3=0.009

From the question we are told that

d(v)= \frac{2.15v^2}{64.4f}

Generally the equation for the f is mathematically given as

f= \frac{2.15v^2}{64.4*d(v)}

Therefore

For v=20 and f=38

f= \frac{2.15(20)^2}{64.4*(38)(20)}

f=0.02

For v=30 and f=86

f=\frac{2.15(30)^2}{64.4*(86)(30)}

f=0.01

For v=40 and f=153

f=\frac{2.15(40)^2}{64.4*(153)(40)}

f=0.009

The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds
600 people. By selling​ tickets, the members would like to raise ​$
3,300 every night to cover all expenses. Let d represent the number of adult tickets sold at ​$
7.50. Let s represent the number of student tickets sold at ​$
4.50 each. If all
600 seats are filled for a​ performance, how many of each type of ticket must have been sold for the members to raise exactly ​$
3,300​? At one performance there were
two times as many student tickets sold as adult tickets. If there were
360 tickets sold at that​ performance, how much below the goal of ​$
3,300 did ticket sales​ fall?

Answers

a) At $3,300 for 600 seats, the average price per seat is 3300/600 = $5.50. The mix of tickets that results in that average can be found using an X diagram as shown below. The numbers on the right are the differences along the diagonals. When they are multiplied by 2, they add to 600. This shows that the required sales for revenue of $3,300 are
200 adult tickets
400 student tickets

b) When 3 student tickets are sold for each adult ticket, the average seat price is
(3*$4.50 +7.50)/4 = $5.25
Then the shortfall in revenue is ...
$3,300 -480*$5.25 = $780

The equation representing the right table is

.

The solution to the system of equations is

Answers

Answer:

The equation representing the left table is:  

y = 1.5x – 6

The equation representing the right table is:  

y = –4x + 6.1

The solution to the system of equations is:  

(2.2, –2.7)

Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

What is slope intercept form of line?

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The first table is

x            y

0           -6

1            -4.5

2            -3

3             -1.5

Slope = -4.5+6/1

=1.5

Now let us find y intercept

-6=1.5(0)+b

-6=b

So the equation representing the left table is y=1.5x-6

Now let us find second table

x            y

0           6.1

1             2.1

2           -1.9

3            -5.9

m=2.1-6.1/1=-4

Now y intercept

2.1=-4+b

b=2.1+4

b=6.1

Equation representing the right table is y=-4x+6.1

Now equate two equations

1.5x-6=-4x+6.1

1.5x+4x=6.1+6

5.5x=12.1

x=12.1/5.5

x=2.2

and y=-4(2.2)+6.1

y=-8.8+6.1

y=-2.7

Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

Leigh-Anne invests £2500 for 4 years in a savings account.
She gets 3% per annum compound interest.
How much money does Leigh-Anne have at the end of 4 years.​

Answers

Answer:

After 4 years, Leigh-Anne will have £ 2,813.77 in her account.

Step-by-step explanation:

Given that Leigh-Anne invests £ 2500 for 4 years in a savings account, and she gets 3% per annum compound interest, to determine how much money does Leigh-Anne have at the end of 4 years, the following calculation must be performed:

X = 2,500 x (1 + 0.03 / 1) ^ 4

X = (2,500 x 1,003) ^ 4

X = 2,813.77

Thus, after 4 years, Leigh-Anne will have £ 2,813.77 in her account.
