Answer:
The (f) x is defined by the values of inverse function.
Step-by-step explanation:
There are equations which are solved using the log function. In the given equation the p (x) is the inverse function of the x+1 due to the log values. The mod function is used to define the equation based on the value of the x.

a^2 + b^2 = c^2
In this case we're looking for C
so
(3)^2 + b^2 = (6)^2
9 + b^2 = 36
b^2 = 36-9
√b^2 = √27
b = 3√3
Answer:
the answer is actually d= 27

Answer:
x=8
Step-by-step explanation:
Let's solve your equation step-by-step.
2 /5 x=3 1 /5
Step 1: Simplify both sides of the equation.
2 /5 x= 16 /5
Step 2: Multiply both sides by 5/2.
( 5 /2 )*( 2 /5 x) =( 5 /2 )*( 16 /5 )
x=8

Highest common factor of 15 30 and 45
Step-by-step explanation:
I believe it is 15...all the numbers can be divided by 15, since 15 is the smallest number it is also the highest common factor only because 30 and 45 can be divided by 15
.......hope it helps!
Answer:
15
Step-by-step explanation:
Find the prime factors for each number as:
45 =3 × 3 × 5
30 = 2 × 3 × 5
15 = 3 × 5
Now identify the common factors and determine the GCF:
Therefore:
HCF = 3 × 5 = 15

A submarine is descending at a rate of 7 feet per second.
A 2-column table with 4 rows. Column 1 is labeled Seconds with entries 1, 2, 3, 4. Column 2 is labeled Feet with entries 7, 14, 21, 28.
Which statements are true? Select all that apply.
The number of seconds causes a change in the number of feet the sub descends.
The number of feet the sub descends causes a change in the number of seconds.
The equation is f = 7s.
The equation is s = 7f.
As the number of seconds increases, the number of feet the sub descends increases.

Answer:
88 is a solution to 1/8 x =11, since a solution means that x is equal to that number, so in this scenario, x=88. When substituted(88*0.125), the same answer, 11, is obtained.

A sample of 64 account balances from a credit company showed an average daily balance of $1,040. The standard deviation of the population is known to be $200. We are interested in determining if the mean of all account balances (i.e., population mean) is significantly different from $1,000. 1. State the null and alternative hypothesis. 2. Compute the test statistic. 3. Compute the p-value. 4. Based on the p-value and the significance level of 0.05% make a decision regarding the hypotheses. 5. Interpret your results in the context of the problem.
Answer:
See step by step exlanation
Step-by-step explanation:
Assuming normal distribution
N( μ₀ , σ )
In this case N ( 1000, 200)
From a random sample of 64 accounts we get:
n = 64
x = sample mean x = 1040
σ = standard deviation of the population σ = 200
1.-Test Hypothesis
Null Hypothesis H₀ x = μ₀ = 1000
Alternative Hypothesis Hₐ x ≠ μ₀
The alternative hypothesis implies a two tail-test. Given that n > 30 and σ is known we will use z-table
2.- z(s) = ( x - μ₀ ) / σ/√n
z(s) = ( 1040 - 1000 ) / 200/ √64
z(s) = 40*8/200
z(s) = 1,6
3.-P-val for z (score 1,6) p-value = 0,0548
4.- If significance level is 0,05 then α = 0,05 and α/2 = 0,025
p-value > α/2
Then the z(s) < z(c) 1,6 < 1,96 where z(c) is z score for α/2
We should accept H₀
5.-We can claim that at 95 % (of Confidence Interval) the population mean is not significantly different from 1000 $

Find the area of the figure.
8 m
15 m
Rounded to the nearest tenth, the area is
square meters.
Answer:
145.1 square meters
Step-by-step explanation:
The figure is composed of a rectangle and a semicircle.
Therefore, area of the figure = area of the rectangle + area of the semicircle
✔️Area of the rectangle = L*W
L = 15 m
W = 8 m
Area of rectangle = 15*8 = 120 m²
✔️Area of semicircle = ½(πr²)
r = ½ of 8 = 4 m
Area of semicircle = ½*π*4²
Area of semicircle = 25.1327413 m²
✔️Area of the figure = 120 + 25.1327413 = 145.132741 ≈ 145.1 m² (nearest tenth)

Answer:
22 ounces
Step-by-step explanation:
6 ounces = $2.10
$2.10 / 6 = $0.35 per ounce
14 ounces = $5.04
$5.04 / 14 = $0.36 per ounce
22 ounces = $7.26
$7.26 / 22 = $0.33 per ounce (cheapest)
Name the two congruent triangles
Answer:
∆ABE ≅ ∆DCE by SAS Congruence Theorem.
Step-by-step explanation:
The diagram given indicates the following:
<E ≅ <E (vertical angles)
AE ≅ DE
BE ≅ CE
Thus, an included angle, <E, and two side lengths, AE and BE, in ∆ABE are congruent to an included angle, <E, and two corresponding side lengths, DE and CE, in ∆DCE. By the SAS Congruence Theorem, both angles are congruent to each other.
Therefore:
∆ABE ≅ ∆DCE by SAS Congruence Theorem.

Answer:
16
Step-by-step explanation:
Hey There!
So the x values are the same so all we have to do is subtract the y values
to be more specific y1-y2
so the distance is equal to 7--9
the negative signs cancel out so now its 7+9
7+9=16
so the distance between the two points is 16
hope this helps :)
Answer:
D. 16 units
Step-by-step explanation:
You could draw a coordinate plane or think of it this way:
They will all be in line with -4 and they will be at -9 and 7. You should add them together to find the distance. 9 + 7 = 16
D. 16 units

Step-by-step explanation:
Kate’s father is a baker at the Morning Muffin Bakery. This morning the oven wasn’t working correctly and 2 dozen muffins burned. Kate’s father gave ¼ of what was left to Kate to take to school. He wrapped up ½ of the remaining muffins and sold them to the grocery store down the street. He then wrapped ⅓ of what was remaining and gave them to the coffee shop to sell. That left Kate’s father with a dozen muffins to sell at the bakery. How many muffins did Kate’s dad bake?
Answer:
64
Step-by-step explanation:
Step 1: 12 divided by 3 = 4. 12+4 = 16.
I need to know what ⅓ of 12 is so I can continue the problem without messing up.
Step 2: 16*2 = 32.
Half of however many are left is 16.
Step 3: 32 divided by 4 is 8. 32+8 is 40. Two dozen is 24. 40 + 24 = 64.
Now we know the answer.
Boom.

The ribbon cost per foot $0.6 per foot
Step-by-step explanation:
Total number of ribbon used = (5.75 + 11.75) = 17.50 feet
17.50 feet of ribbon cost = $10.50
1 foot of ribbon cost = x
Cross Multiply
17.50 × x = 1 foot × $10.50
x = 1 foot × 10.50/17.50
x = $0.6
The ribbon cost per foot $0.6 per foot
