Find the total surface area of the following cone. Leave your answer in terms of Pi. 4cm 3cm
The triangle formed from the height of the cone and the radius of its base is a special 3,4,5 triangle. The slant height is 5cm.
Recall that the area of a circle = pi*r^2
Substitute 3 in for r
Area = pi * (3)^2 = 9pi
SA = pi*r*l + B
Substitute our values into the equation
SA = pi * 3 * 5 + 9pi
SA = 15pi + 9pi
SA = 24pi cm^2

A new popular midsize car has a retail price of $25,000. The midsize car's value M(t) is given by the exponential model M of t is equal to 25,000 times the quantity four fifths to the power of t where t represents the time in years. Identify the domain, in yearly intervals, that contains all the years the car's value is less than $1,000.
[13, ∞)
[14, ∞)
[15, ∞)
[16, ∞)
Answer:
Its C
Step-by-step explanation:
Just finished the homework and got it right
Using exponential functions, it is found that the correct option is given by: [15, ∞)
-------------------------
The exponential function given in this exercise is:
[tex]M(t) = 25000(\frac{4}{5})^t[/tex]
-------------------------
The domain that contains all the years the car's value is less than $1,000 is composed by the values of t for which:
[tex]M(t) < 1000[/tex]
Thus, we have to solve the exponential inequality.
[tex]M(t) < 1000[/tex]
[tex]25000(\frac{4}{5})^t < 1000[/tex]
[tex](\frac{4}{5})^t < \frac{1}{25}[/tex]
[tex]\log{(\frac{4}{5})^t} < \log{\frac{1}{25}}[/tex]
[tex]-0.0969t < -1.39794[/tex]
[tex]0.0969t > 1.39794[/tex]
[tex]t > \frac{1.39794}{0.0969}[/tex]
[tex]t > 14.43[/tex]
Rounding, t greater than 15 years, and the correct option is:

Evaluate 2a2+5/7+b when a=−6 and b=−2
Step-by-step explanation:
2a^2+5/7+b
a= -6
b= -2
solution
2(-6 x -6 )+5/7 +-2
2(36)+5/7+( -2 )
2x36=72
so it will be
72+5/7+ (-2)
72+5=77
77/7+(-2)

which is small 1.2 or 1.7
Answer:
1.2 is less so your answer should be 1.2.
= 1.2
If you're measuring mountains, they're both huge.

Gina paid $131 for a car stereo on sale for 30% off. There was also 7% sales tax on the purchase. Find the original price of the stereo
Answer:
It would be 98.12 dollars
Step-by-step explanation:
Hope this helps. :D
The original price of the car stereo before any discounts or taxes was approximately $187.14.
We have,
Gina paid $131 for the car stereo after it was discounted by 30%.
Let's represent the original price of the stereo as "x" dollars.
The discounted price would be 70% (100% - 30%) of the original price:
Discounted price = 0.70 * x
Given that Gina paid $131, we can set up the equation:
0.70 * x = 131
Now, solve for "x" by dividing both sides of the expression by 0.70:
x = 131 / 0.70
x ≈ 187.14
So, the original price of the stereo before the discount was approximately $187.14.
There was also 7% sales tax on the purchase.
To find the sales tax amount, we calculate 7% of the original price:
Sales tax = 0.07 * 187.14 ≈ 13.10
Now, to find the total original cost before the sales tax, we add the original price and the sales tax:
Total original cost = Original price + Sales tax
Total original cost ≈ 187.14 + 13.10 ≈ 200.24
Therefore,
The original price of the car stereo before any discounts or taxes was approximately $187.14.

Step-by-step explanation:
For what value of t is f (t) = 0.0625
9514 1404 393
Answer:
t = 4
Step-by-step explanation:
It can be useful to convert the numbers to ratios of integers.
0.0625 = (0.5)^t
1/16 = (1/2)^t
1/2^4 = 1/2^t
4 = t . . . . . . . match exponents
__
If you like, you can solve this using logarithms.
0.0625 = 0.5^t
log(0.0625) = t×log(0.5)
t = log(0.0625)/log(0.5)
t = 4
