Answer: 12 Inches
Step-by-step explanation: If the wood is originally 13 inches and the piece sawwed off was one inch, then 13-1=12 Inches.
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

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

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 betterthe graph shown is the solution set for which of the following inequalities

If there is 1/3 of quantity A for every 4/9 of quantity B, how much of quantity A is there for 2/5 of quantity B?
Answer:
The ratio equivalent to 5/3 is
For example, if we have a ratio 250 to 150, we can simplify it by dividing both numbers by 10 and then by 5 to get 5 to 3: 250 : 150 25 : 15 5:3 . The ratio 5 to 3 is the simplest form of the ratio 250 to 150, and all three ratios are equivalent.
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

Find the measure of angle y.
A)
19
B)
22
41
D)
120
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
Andre's personal record for the long jump is 16 feet.
Then, he jumps 10% farther.
What is Andre's new personal record for the long jump?
Answer: 17.6
Step-by-step explanation:
16*10/100
160/100
1.6+16
17.6
Answer:
17.6 feet
Step-by-step explanation:
16*10%(or 0.10)= 1.6 feet which is 10% of his 16 foot jump
16+ the 10% increase of 1.6= 17.6 feet as his new record
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 - 6Fill in the blanks below

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
Find 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

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
