Answer:
m<y=22º
Step-by-step explanation:
180-19-41=120
m<1=120º
m<1≅m<2
m<2=120º
180-120-38=22
so y=22º

What is the value of this expression?
1.5(−2.4+(−5.3))
Answer:
-11.55
Step-by-step explanation:
(to get the numbers out of the brackets you have to multiply all the numbers in the brackets to the number that is there, and in this case its 1.5)
1.5x(-2.4)= -3.6
1.5×(-5.3)= -7.95
after that, you add them (because there is a plus sign, not a minus, multiplication sign or a division sign.)
-7.95+ -3.6= -11.55
answer= -11.55

Step-by-step explanation:
evaluate -(2-^6)(2^3)
Answer:
The answer = -512
Step-by-step explanation:
To find -(2-^6)(2^3)
We have that -(2-^6) = {-(-2*-2*-2*-2*-2*-2)}=
-(64) which is -64
For (2^3) = (2*2*2) =8
Therefore -(2-^6)(2^) = (-64)(8)
which is = -512
So therefore -(2-^6)(2^3) = -512
Please help! Suppose f(x)=-8x^7 +8x-6
then f(-x)=________
Answer:
f(-x) = 8x⁷ - 8x - 6Step-by-step explanation:
f(x) = -8x⁷ + 8x - 6
To find f(-x), we'll need to plug in -x instead of x.
f(x) = -8x⁷ + 8x - 6
f(-x) = -8(-x)⁷ + 8(-x) - 6
f(-x) = 8x⁷ - 8x - 62y-5w

Evaluating Expressions
Answer:
[tex]2y - 5w \\ here \\ \: y = - 3 \\ w = - 1 \\ then \: = > 2 \times (- 3) - 5 \times ( - 1) \\ = 2 \times - 3 - 5 \times - 1 \\ = - 6 + 5 \\ = - 1 \\ thank \: you[/tex]
The solution of expression after substituting given values is, - 1
We have to give that,
An expression is defined as,
2y - 5w
Here, y = - 3
w = - 1
Now, Substitute y = - 3 and w = - 1 in above expression,
we get;
⇒ 2y - 5w
⇒ 2 × - 3 - 5 × - 1
⇒ - 6 + 5
⇒ - 1
Therefore, The solution is, - 1

Points A, B, and C are collinear. Point B is between A and C. Find the length indicated. AB= 5x-15, BC=3x-5, and AC=28. Find AB
Answer: AB is 15
Step-by-step explanation: First, you need to draw a picture and label the parts of the line: AB=5x-15; BC= 3x-5; AC =28. Because of the segment addition postulate, you set the equation to be 5x-15+3x-5=28. Then you solve:
5x-15+3x-5=28
Add like terms:
8x-20=28
Add 20 to both sides
8x=48
Divide by 8
x=6
Now, you need to find the measure of AB, so you plug the 6 into the x variable for 5x-15
5(6)-15
30-15
AB=15
A triangle has a perimeter of 48 feet. If the three sides of the triangle are n, 4n−2, and 4n−4, what is the length of each side?
Answer:
6; 22; 20 (ft.)
Step-by-step explanation:
1) if the length of the each side are: n; 4n-2 and 4n-4, then the expression of the perimeter can be written: P=n+4n-2+4n-4 or P=9n-6.
2) if according to the condition perimeter is 48 (ft.), then
9n-6=P; ⇔ 9n-6=48; n=6.
3) if n=6, then the required lengths of the sides are:
n=6 (ft.);
4n-2=22 (ft.);
4n-4=20 (ft.)

Find the exact circumference of the circle. please help?
Answer:
3rd option
Step-by-step explanation:
We first need to find the diameter of the circle.
We know this is a square because all sides are marked by a line so this means they are equal. Let find the diagonal of the square to find all parts of the square.
The diagonal of a square is
[tex]a \sqrt{2} [/tex]
where a is the side lengths of the square.
So this means the diagonal of the square is
[tex]18 \sqrt{2} [/tex]
The diagonal is also the diameter of the main circle. The formula for circumference is
[tex]d\pi[/tex]
where d is the diameter.
So the diameter is
[tex](18 \sqrt{2} )\pi[/tex]
or
[tex]18\pi \sqrt{2} [/tex]
The third option is correct

Todd and Garrett began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Todd took a test in Math and earned a 74.6, and Garrett took a test in English and earned a 68.8. Use the fact that all the students' test grades in the Math class had a mean of 70.6 and a standard deviation of 11.9, and all the students' test grades in English had a mean of 63.7 and a standard deviation of 8.6 to answer the following questions.
Required:
a. Calculate the z-score for Todd's test grade.
b. Calculate the z-score for lan's test grade.
c. Which person did relatively better?
Part A
For Todd's class, we have this given info:
mu = 70.6 = population mean of math scoressigma = 11.9 = population standard deviation of math scoresCompute the z score for x = 74.6
z = (x-mu)/sigma
z = (74.6 - 70.6)/(11.9)
z = 0.34 approximately
Side note: Convention usually has z scores rounded to two decimal places. If your teacher instructs otherwise, then go with those instructions of course.
Answer: 0.34======================================================
Part B
For Garret's English class, we have:
mu = 63.7sigma = 8.6Compute the z score for x = 68.8
z = (x-mu)/sigma
z = (68.8 - 63.7)/(8.6)
z = 0.59 approximately
Answer: 0.59======================================================
Part C
Garret has the higher z score, which means that Garret did relatively better to his classmates compared to Todd's performance (in relation to his classmates). The z score is the distance, in units of standard deviation, the score is from the mean. Positive z values are above the mean, while negative z values are below the mean.
Answer: Garret did relatively betterFind an equation of the tangent line to the curve y = 10/(1 + e^-x) at the point (0,5)
Compute the derivative, dy/dx (use the chain rule):
y = 10/(1 + e ⁻ˣ) = 10 (1 + e ⁻ˣ)⁻¹
===> dy/dx = -10 (1 + e ⁻ˣ)⁻² (-e ⁻ˣ) = 10e ⁻ˣ/(1 + e ⁻ˣ)²
Evaluate the derivative for x = 0 to get the slope of the tangent to the curve at (0, 5) :
dy/dx (0) = 10e ⁰/(1 + e ⁰)² = 10/(1 + 1)² = 10/4 = 5/2
Use the point-slope formula to get the equation of the tangent line:
y - 5 = 5/2 (x - 0)
===> y = 5/2 x + 5
There are 500 seats on a plane flying to San Francisco. 20% of the seats are next to a window. How many of the seats are next to a window?
Answer:
There are 100 seats that are next to a window.
Step-by-step explanation:
You have to calculate 20% of the total number of seats.
20% can also be written as 20/100
so 20/100 x 500. If you solve this then you will get 100. Therefore, 100 seats are next to a window.
Answer: 100 seats are next to a window.
Step-by-step explanation: 1. We assume, that the number 500 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 500 is 100%, so we can write it down as 500=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 500=100%
2) x=20%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
500/x=100%/20%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 20% of 500
500/x=100/20
(500/x)*x=(100/20)*x - we multiply both sides of the equation by x
500=5*x - we divide both sides of the equation by (5) to get x
500/5=x
100=x
x=100
now we have:
20% of 500=100
find the equation of the line that is perpendicular to y=1/2x -4 and contains the point (4, 5)
Answer:
the equaion of the new line is y = -2x + 13
Step-by-step explanation:
The slope of this line is 1/2. Recall that if we are given such a slope and want the slope of a line perpendicular to the given line, we find the negative reciprocal of the slope of the given line. Here, given m = 1/2, the slope of any line perpendicular to the given line is m = -2.
Now insert this info into the standard slope-intercept equation of a line:
y = mx + b becomes 5 = (-2)(4) + b. Solve this for b:
5 + 8 = b = 13.
Thus, the equaion of the new line is y = -2x + 13.
