How many x-intercepts can an absolute value graph have?
Answer:
Zero, One, Two
Step-by-step explanation:
It can never touch the x-axiswhen it's like
[tex]y=a|x-b|+c[/tex]
with
[tex]c>0[/tex]
it will be upward
it can touch only once when it's like[tex]y=a|x-b|[/tex]
it will touch it in [tex](b,0)[/tex]
It can touch twice when it's like[tex]y=a|x-b|-c[/tex]
with
[tex]c>0[/tex]
the equations are just an example, there can be other ways too
have three or more it's impossible, because the absolute value graph is the union of two lines, and each line at most can touch the x-axis once

Anika was shown a reduction of a complex figure.
2 complex figures. Side A corresponds to a side with length 35 centimeters. Side B corresponds to a side with length 25 centimeters. A side with length 15 centimeters corresponds to a side with length 60 centimeters.
Figures not drawn to scale.
What can Anika conclude about the scale factor and missing measurements? Select three options.
The scale factor is 0.60.
The scale factor is 0.25.
The length of side A is 8.75 cm.
The length of side A is 21 cm.
The length of side B is 6.25 cm.
Answer:
Scale factor is .25.
Step-by-step explanation:
Side A is .25 times 35 which is 8.75. Side b is .25 (25)= 6.25
Answer:
B: The scale factor is 0.25.
C: The length of side A is 8.75 cm.
E: The length of side B is 6.25 cm.
Step-by-step explanation:
To find the answer of 8.75 in C multiply 35 x .25
To find E multiply 25 by .25.
And the scale factor is .25 becuase the original is 1/4 the new perimeter.

When we multiply this together
= (7.006 × 5.09 ) × 10(⁴¹+²²)

A polynomial is divided by (x - 2), the quotient is (x – 6), and the remainder is -6
What is the original polynomial
=========================================================
Explanation:
n = numerator polynomial = unknown (what we want to solve for)
d = denominator polynomial = x-2
q = quotient = x-6
r = remainder = -6
Based on that, we can say,
n/d = q + r/d
n = q*d + r ... multiply every term by d
n = (x-6)(x-2) + (-6) .... substitution
n = x^2-8x+12-6
n = x^2-8x+6
Dividing (x^2-8x+6) over (x-2) leads to a quotient of (x-6) and a remainder of -6.

Identify the function's local and absolute extreme values, if any, saying where they occur. f(x) = x^3 + 4x^2 - 3x - 4 A) local maximum at x = -1/3; local minimum at x = 3 B) local maximum at x = -1; local minimum at x = 1 C) local maximum at x = -3; local minimum at x 1/3 D) local maximum at x = -1; local minimum at x = 1
Answer: C) local maximum at x = -3; local minimum at x = 1/3
Step-by-step explanation:
Given the function:
f(x) = x^3 + 4x^2 - 3x - 4
Set f'(x) = 0
f'(x) = 3x² + 8x - 3
f'(x) = 0
3x² + 8x - 3 = 0
Using the quadratic function calculator :
x = - 3 or x = 1/3
Critical points = - 3 ; 1/3
To find the maximum and minimum points :
f''(x) = 6x + 8
Substitute the values of X in
At x = - 3
6(-3) + 8
-18 + 8 = - 10
At x = 1/3
6(1/3) + 8
2 + 8 = 10
Value of f''(x) at - 3 is negative, hence - 3 is the maximum point
Value of f''(x) at 1/3 is positive , hence 1/3 is the minimum point

Step-by-step explanation:
Zander and Chloe were comparing the number of texts they send. Zander has already sent 38 texts and says he sends 28 texts per day. Chloe has sent 52 texts already and says she send 26 texts a day. After __ days, Zander and Chloe will have sent the same amount of texts. A. 5 days B. 6 days C. 7 days D. 9 days
Answer:
(C) 7
Step-by-step explanation:
We can create an equation here.
We know that Zander has 38 texts. He sends 28 texts per day.
Let us represent x as the number of days.
This can be represented as an expression, [tex]38+28x[/tex].
Same logic for Chloe.
52 texts already, 26 texts per day: [tex]52+26x[/tex]
If their texts are equal, both expression are equivalent to each other.
[tex]38+28x = 52+26x[/tex]
We can simplify this equation to get x on one side of it.
Subtract 38 from both sides:
[tex]28x = 14+26x[/tex]
Subtract 26x from both sides:
[tex]2x =14[/tex]
Divide both sides by 2:
[tex]x = 7[/tex]
So, Chloe and Zander will have sent the same amount of texts after 7 days.
Hope this helped!
A chain weighs 9 pounds per foot. How many ounces will 5 inches weigh? Round your answer to the
nearest tenth as needed.
Answer:
60 ounces.
Step-by-step explanation:
A chain weighs 9 pounds per foot.
We are to find the number of ounces 5 inches weigh.
First we find how many feet are in 5 inches.
1 foot = 12 inches
how many feet? = 5 inches.
Cross-multiplying gives;
[tex]\frac{5}{12} * 1 = \frac{5}{12}[/tex] feet
1 foot of the chain = 9 pounds
[tex]\frac{5}{12}[/tex] feet = how many pounds?
Cross-multiplying gives;
[tex]\frac{5}{12} * 9 = 3.75[/tex] pounds
1 pound = 16 ounces
3.75 pounds = how many ounces?
Cross-multiplying gives;
[tex]\frac{3.75 * 16}{1} = 60[/tex] ounces.
The number of ounces will 5 inches weigh is 66.667 oz.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A chain weighs 9 pounds per foot.
We know that
1 foot = 12 inches.
1 pound = 16 ounces.
Now based on this,
= 5 inches 1/12 x foot/ inches x 10 x pound/ feet x 16
= 5 x 10 x 16 / 12
= 66.667 oz.
Hence, the chain weight 66.6667 oz.

You asked a sample of individuals what kind of animal is their favorite. Of the 167 individuals in your sample, 52 of them answered "dog". Which of the following gives a 95% confidence interval for the true percentage of individuals whose favorite animal is a dog
a. (23.4%, 38.9%)
b. (16.8%, 32.3%)
c. (3.1696, 3.2696)
d. (2.21%,4.21%)
Answer:
a. (23.4%, 38.9%)
Step-by-step explanation:
Р = x/∝ = 52/167 = 0.3114
At 95% confidence level
∝ = 1 - 0.95 = 0.05
Zerit = Z0.05/2 = 1.96
Р ± Zerit [tex]\sqrt{P(1-P) / n}[/tex]
= 0.3114 ± 1.96 [tex]\sqrt{0.3114(1-0.3114) / 167}[/tex]
= 0.3114 ± 0.0702
= 0.2412 or 0.3816
= 24.1% or 38.1%
Closest Option = 23.4%, 38.9%
A 95% confidence interval for the true percentage of individuals whose favorite animal is a dog is (23.4%, 38.9%)
The formula for calculating the confidence interval based o proportion is expressed according to the formula:
[tex]p\pm z\sqrt{\frac{p(1-p)}{n} }[/tex]
z is the z-score at 95% confidence interval
p is the proportion
n is the sample size
Given the following parameters
p = 52/167 = 0.31
z = 1.96
n = 167
Substitute the given parameters into the formula to have:
[tex]CI=0.31 \pm 1.96\sqrt{\frac{0.31(1-0.31)}{167} } \\CI=0.31 \pm 1.96\sqrt{\frac{0.31(0.69)}{167} } \\CI=0.31 \pm 1.96(0.035)\\CI=0.31\pm 0.0701\\CI = (0.31-0.0701, 0.31+0.0701)\\CI=(0.234, 0.389)[/tex]
Hence a 95% confidence interval for the true percentage of individuals whose favorite animal is a dog is (23.4%, 38.9%)

The sum of the ages of Jacob and Jasmine is 66 years. 6 years ago, Jacob's age was 2 times Jasmine's age. How old is Jacob now?
Answer:
Jacob's age is 42
Jasmine's age is 24
Step-by-step explanation:
Let Jacob's age be x
Let Jasmine's age be y
x + y = 66
x - 6 = 2(y - 6)
x - 6 = 2y - 12
x - 2y = -12 + 6
x - 2y = -6
x + y = 66 ------- (1)
x - 2y = -6 ------- (2)
From (1),
x = 66 - y -------- (3)
Substitute the value of x in (2)
x - 2y = -6
66 - y - 2y = -6
-3y = -6 - 66
-3y = -72
y = -72/-3
y = 24
Solve for x in (1)
x + y = 66
x + 24 = 66
x = 66 - 24 = 42
x = 42, y = 24
