ERROR ANALYSIS Describe and correct the error in
graphing and comparing
y= x^2and y = 0.5x^2.
Answer:
The graph should be stretched rather than become narrower.
Step-by-step explanation:
To figure this out, just create some example points.
At x = 0, your y-value will always be 0. But if you were to plug in the value 1, you would get a y-value of 1 in y=x^2, but a value of 0.5 in y=0.5x^2. If you were to plug in a value of 2, you would get a value of 4 in y=x^2, but a value of 2 in y=0.5x^2.
If you continue this pattern for a few more points, then plot them, you will see that adding a coefficient of 0.5 simply stretches the graph

At Trendy Tailor Boutique's annual end-of-season sale, every necktie in the
shop gets marked down. Will purchased 7 neckties during the sale. Each
necktie cost $8 less than its full price. He paid a total of $147.
Which equation can you use to find f, the cost of each necktie at full price?
By direct calculation, we will see that the full price of each necktie is $29.
How to find the complete price of each necktie?
Let's say that the full price of each necktie is f.
We know that Will each necktie costed $8 less than the full price, so he paid:
(f - $8) for each one.
Knowing that he bought 7 and paid a total of $147, we know that he paid:
$147/7 = $21
Then we need to solve:
(f - $8) = $21
Solving for f, we have:
f = $21 + $8 = $29.
So the full price of each necktie is $29.

Ingrid mixes 3. 6 pounds of almonds with some raisins to make a trail mix. She divides the trail mix into 12 equal portions. Each portion weighs 0. 7 of a pound. How many pounds of raisins did she use to make the trail mix? Express the answer to the nearest tenth. 2. 9 4. 8 5. 1 7. 2.
The weight of the 12 trail mixed is 8.4 pounds. But 3.6 pounds of the almonds. Then the Ingrid mix is 4.8 pounds. The correct option is B.
What are ratio and proportion?A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Ingrid mixes 3.6 pounds of almonds with some raisins to make a trail mix.
She divides the trail mix into 12 equal portions.
Each portion weighs 0.7 of a pound.
Then the weight of the 12 trail mixed will be.
0.7 × 12 = 8.4
The weight of the 12 trail mixed is 8.4 pounds. But 3.6 pounds of the almonds. So, the mix Ingrid will be
8.4 - 3.6 = 4.8
Thus, the Ingrid mix is 4.8 pounds. The correct option is B.

29. y=2x² - 3x - 35
31: y=-7x² - 2x + 5
Answer:
29. (5,0) and (-7/2,0)
30. (-1,0) and (5/7,0)
Step-by-step explanation:
29. y=2x² - 3x - 35
y = (x-5)(2x+7)
y is 0 at x = 5 and -(7/2)
31: y=-7x² - 2x + 5
y = -(x+1)(7x-5)
y is 0 at -1 and 5/7

NEED THESE ASAP: You have an isosceles triangle where the two legs form a 90 degree angle. One of these legs is 2cm. What is the hypotenuse of the triangle? Express your answer using two decimal places only.
Why would you make the size of one of the sides of a right triangle if its other side is 12cm and the hypotenuse is 20cm?
Answer:
1) 2.83 cm
2) 16 cm
Step-by-step explanation:
1)
A isosceles right triangle has two 45° angles and a 90° angles. The legs are congruent.
If one leg measures 2 cm, then both legs measure 2 cm.
Then we use the Pythagorean theorem to find the hypotenuse.
a² + b² = c²
(2 cm)² + (2 cm)² = c²
c² = 8 cm²
c = √8 cm
c = 2.83 cm
Answer: 2.83 cm
2)
a² + (12 cm)² = (20 cm)²
a² + 144 cm² = 400 cm²
a² = 256 cm²
a = 16 cm
Answer: 16 cm
Larry claims that (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are equivalent because they have the same digits and the same operations. Is Larry correct?
Answer:
Larry is wrong
Step-by-step explanation:
Multiplying big numbers will give significantly bigger results then multiplying smaller numbers then adding them. 14 + 12 = 26 & 8 + 12 = 20. 14 x 12 = 68 & 8 x 12 = 96. 96 + 168 is alot less then 26 * 20 so that is why larry is wrong

Emma doesn't have experience using credit cards. In fact, she just got her first one. She is also about to start her first year
of college. She uses her new credit card to purchase textbooks for her classes. The total comes to $300. These are the
terms of her credit card:
• It has a 15% annual interest rate.
• The interest is compounded monthly
• The card has $0 minimum payments for the first four years it is active.
The expression that models this situation is P(1 + r/n)^nt, where (1 + r/n) represents the growth factor of the interest rate.
Answer:
P = $300
r = 0.15
n = 12
$544.61 (to the nearest cent)
[tex]P(1+r)^t[/tex]
$524.70 (to the nearest cent)
Step-by-step explanation:
P = principal amount = $300
r = annual interest rate in decimal form = 15% = 15/100 = 0.15
n = number of times interest is compounded per unit t = 12
How much she'll owe in 4 years
P = 300
r = 0.15
n = 12
t = 4
[tex]P(1+\frac{r}{n})^{nt}=300(1+\frac{0.15}{12})^{12 \times 4}[/tex]
= $544.61 (to the nearest cent)
Yearly compounding interest rate
[tex]P(1+r)^t[/tex]
How much she'll owe in 4 years at yearly compounding interest
[tex]P(1+r)^t=300(1+0.15)^4[/tex]
= $524.70 (to the nearest cent)
