9 POWERED C = 243 (INDICES)
9^c = 243
3^(c)*2 = 243
3^(c)*2 = 3^5
Since the bases are the same the powers can be equated.
2*c =5
c = 5/2
c = 2 1/2
Check
9^2.5 = 243

Answer:
let A (2, 6) be (x1, y1)
B (-5, 2) be (x2, y2)
distance AB =√[(x2 - x1)² + (y2 - y1)²]
√[(-7)²+ (-4)²]

please help algebra 2 question D:
First, let's let's evaluate the numerator and denominator separately.
The numerator: (-2)^2(3)(4) - (-1) = 48 + 1 = 49
The denominator: (-2)^2 = 4
Now that the numerator and denominator are simplified, let's take the square root of 49/4
sqrt(49/4) = 3.5

Answer:
40.38912735 or about 40 miles per hour (rounded to the nearest whole number)
Step-by-step explanation:
1.) You want to convert kilometers per hour to miles per hour.
2.) There are 0.62137119 miles in 1 kilometer.
3.) Multiply 65 by 0.62137119
4.) That equals 40.38912735
5.) This answer can be rounded to 40 mph.

13. A new CD costs $13.79, plus $0.97 in sales tax. How much do 3 new CDs cost? Explain how
you found your answer.
Answer:
the cost of the three new CDs is $44.28
Step-by-step explanation:
Here in this question, we are interested in calculating the cost of 3 new CDs cost.
From the question, we already know the cost of one. The cost of three would be 3 multiplied by the cost of one.
The cost of the three excluding the sales tax = $13.79 * 3 = $41.37
The sales tax for the three pieces = 3 * $0.97 = $2.91
The cost of the three CDs including the sales tax = $41.37 + $2.91 = $44.28

Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
Thus, [tex]x+3x=180[/tex]
[tex]4x=180[/tex]
Divide both sides by 4:
[tex]\frac{4x}{x} =\frac{180}{4}[/tex]

Answer:
Step-by-step explanation:
3z = 12
z = 4
5y - 4 = 1
5y = 5
y = 1
2x + 1 - 4 = -7
2x - 3 = -7
2x = -4
x = -2

9. In City A, the temperature rises 9 from 8 A.M. to 9 A.M. Then the temperature drops 8 from 9 A.M. to 10 A.M. In City B, the temperature drops 5º from 8 A.M. to 9 A.M. Then the temperature drops 4º from 9 A.M. to 10 A.M.
a. What expression represents the change in temperature for City A?
b. What integer represents the change in temperature for City A?
c. What expression represents the change in temperature for City B?
d. What integer represents the change in temperature for City B?
e. Which city has the greater change in temperature from 8 A.M. to 10 A.M.? 10.
The expression for temperature change in City A is 9 + (-8)
The amount the temperature changes for City A = 1°F
The expression for temperature change in City B is -1 + (-3) = -4°F
The amount the temperature changes for City B = -4°F
Calculations and ParametersBased on the available data:
In City A, the temperature rise from 8 am to 9 am = 9°FIn City A, the temperature drop from 9 am to 10 am = 8°FIn City B, the temperature drop from 8 am to 9 am = 1°FIn City B, the temperature drop from 9 am to 10 am = 3°FThe expression for that represents the temperature change from 8 am to 10 am is, therefore;
For City AThe temperature change from 8 am to 10 am are
8 am to 9 am = +9°F9 am to 10 am = -8°FSum, change from 8 am to 10 am = 9 + (-8) = 1°F
For City BThe temperature change from 8 am to 10 am are
8 am to 9 am = -1°F9 am to 10 am = -3°FSum, change from 8 am to 10 am = -1 + (-3) = -4°F
