5. Which two values are NOT solutions for x in the inequality 5x + 3 > 33?
a. 5
b. 6
c. 7
d. 8
Answer:
5 and 6
Step-by-step explanation:
Given the inequality 5x + 3 > 33?
Subtract 3 from both sides
5x + 3 - 3 > 33 - 3
5x > 30
Divide both sides by 5
5x/5 > 30/5
x > 6
Hence the value of x must be greater than 6. The values that are not greater than 6 are 5 and 6. Hence 5 and 6 are not solution for x in the inequality
Chemists use pH as a measure of acidity or alkalinity of a solution. It uses the concentration of hydrogen ions H+ in a logarithmic function. A chemist is studying the alkalinity of a hot spring near a volcano. The hydrogen ion concentration is increasing according to the function f(d) = (0.5 × 10–4)d, where d is the number of days. The function for pH is g(H+) = –log10(H+), where H+ is the hydrogen ion concentration of the solution. Which function shows the pH of the hot spring as a function of d? g(f(d)) = –log10(d) g(f(d)) = –d(log10(0.5 × 10–4)) g(f(d)) = –log10((0.5 × 10–4)d) g(f(d)) = –log10(d × 10–4)
Answer:
[tex]g(f(d)) = -dlog_{10}(0.5 * 10^{-4})[/tex]
Step-by-step explanation:
Given
[tex]f(d) = (0.5 * 10^{-4})^d[/tex]
[tex]g(H+) = -log_{10}(H+)[/tex]
Required
Find the composite function g(f(d))
We have:
[tex]g(H+) = -log_{10}(H+)[/tex]
Substitute f(d) for H+
[tex]g(f(d)) = -log_{10}(f(d))[/tex]
Substitute [tex]f(d) = (0.5 * 10^{-4})^d[/tex]
[tex]g(f(d)) = -log_{10}((0.5 * 10^{-4})^d)[/tex]
Apply law of logarithm
[tex]g(f(d)) = -dlog_{10}(0.5 * 10^{-4})[/tex]
Hence, the function is:
[tex]g(f(d)) = -dlog_{10}(0.5 * 10^{-4})[/tex]

If the exponential model f(x)=9(13)x is written with the base e, it will take the form A0ekx. What is A0 and what is k?
9 × 13ˣ = 9 × exp(ln(13ˣ ))
… = 9 × exp(x ln(13))
… = A₀ × exp(kx)
so that
A₀ = 9
k = ln(13)

Answer:
I got you bro so the sales tax is $0.80 and the total cost is $10.80
Answer:
Sales tax = $0.8Total cost = $10.8Step-by-step explanation:
Now we have to,
→ find sales tax and total cost.
The sales tax will be,
→ 8% of $10.00
→ (10/100) × 8
→ 80/100
→ $0.8
Now the total cost will be,
→ $10 + sales tax
→ 10 + 0.8
→ $10.8
Hence, total cost is $10.8.

A kitchen was remodeled and granite counter tops were installed A rectangular island in the kitchen now has a granite top measuring 8 ft by 5.3 inches. The density of granite is 2.7 kg/cm3.
don't forget to change to inches to feet and feet to centimeters.
how much does the counter top weigh in pounds? 1 kg= 2.2 pounds .
Answer:
Problem: if I correctly recall from my days of carving tombstones, the density of granite is not 2.7 kg/cm³, but 2.7 g/cm³
At 2.7 kg/cm³, the weight is 3,664,392 pounds
at 2.7 g/cm³, the true weight is 3664.39 pounds
Step-by-step explanation:
8 ft = 243.84 cm
5.3 inches = 13.46 cm
6 ft 2 in = 187.96 cm
volume = 243.84 cm x 13.46 cm x 187.96 cm = 616,901.01 cm³
616,901.01 cm³ × 2.7 kg/cm³ x 2.2 lb/kg = 3,664,392 pounds
2.7 g/cm³ = 0.0027 kg/cm³
616,901.01 cm³ × 0.0027 kg/cm³ x 2.2 lb/kg = 3664.39 pounds

Juicy's business Sweet Sauce is profiting at a rate 20,000 dollars per month. The starting balance in Sweet Sauce's account for 2020 was $50,000. How much money will be in Sweet Sauce's account after July 31st? Write an equation for this problem and answer the question. How much money will be in the account after 2 years?
Answer:
-The equation for this problem is:
y=50,000+20,000x
-The money in Sweet Sauce's account after July 31st is $190,000
-The money in the account after 2 years is $530,000.
Step-by-step explanation:
With the information provided, you can say that the money in the account would be equal to adding up the starting balance plus the profit per month for the number of months that have passed, which is:
y=50,000+20,000x, where:
y is the money in the account
x is the number of months that have passed
Now, to find the amount of money in the account after July 31st, you have to consider that this is the 7th month and you have to replace x with 7:
y=50,000+(20,000*7)
y=50,000+140,000
y=190,000
Also, to find the amount the amount of money in the account after 2 years, you have to consider that 2 years is equal to 24 months:
y=50,000+(20,000*24)
y=50,000+480,000
y=530,000
