Solve the logarithmic equation. Round to the nearest ten-thousandth if necessary.
Solve log(4x
+
10) = 3.
Answer: x = 2.5214
Step-by-step explanation:
log(4x+10) = 3
e^(log(4x+10)) = e^3
E^ log cancels out and equals one so
4x + 10 = e^3
4x = e^3 -10
x = (e^3 - 10)/4
x = 2.5214

Luca pays $165 per month for his car loan and an average of $2.30 per gallon of gas. He wants to keep his car expenses under $300 per month. Write and solve an inequality to find the greatest number of gallon "g", Luca can drive in a month while staying within his budget?
Answer:
58.69 gallons is the maximum she can get.
Step-by-step explanation:
165 + 2.3g ≤ 300
subtract 165 from both sides
2.3g ≤ 135
divide by 2.3 on both sides
g ≤ 58.6956521739

Answer: Your answer is 30 percent
Answer:
30%
Step-by-step explanation:
Make a fraction
6/20
There a few different ways to find a percentage, but in this case, I will change the fraction to be out of 100
20 × what = 100?
20 × 5 = 100
Multiply the denoninator by 5
6 / 20 × 5
What we do to the denominator, we must also do to the numerator
6 × 5 / 20 × 5
30/100
Percentages are out of 100, meaning if the fraction has the denominator "100," the numerator is the answer
30%

In ΔUVW, u = 480 cm, v = 180 cm and ∠W=120°. Find the length of w, to the nearest centimeter.
Answer:
591
Step-by-step explanation:
The length of w from the given triangle UVW is 591 cm.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² - 2bc·cosA.
Given that, in ΔUVW, u = 480 cm, v = 180 cm and ∠W=120°.
w² = u² + v² - 2uv·cosW
w² = 480² + 180² − 2×480×180·cos120°
w² = 230400 + 32400 - 172800·(-0.5)
w² = 349200
w = √349200
w = 590.93
w = 591 cm
Therefore, the length of w is 591 cm.

ariana is going to invest in an account paying an interest rate of 1.9% compounded monthly. how much would ariana need to invest,to the nearest ten dollars,for the value of the account to reach $110,000 in 14 years?
9514 1404 393
Answer:
$84,330
Step-by-step explanation:
The compound interest formula gives the value of an investment.
A = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years. Using your given values, we can solve for P.
110,000 = P(1 +0.019/12)^(12·14)
P = 110,000/(1 +0.019/12)^(12·14) ≈ 110,000/1.00158333...^168
P ≈ 110,000/1.30446
P ≈ 84326.04 ≈ 84,330 . . . . dollars
