Answer:
9^3
Step-by-step explanation:
9* 9^2
9*9(9) = 9^3
We could also look at it as
9^1 * 9^2
We know that a^b * a^c = a^(b+c)
9^(1+2) = 9^3
Can someone help me with is
Answer:
It is not equivalent
Step-by-step explanation:
Because the first expression simplified is 3x with the power of 9, and the first expression simplifies to x with a power of 9.
Answer:
No, they are not equivalent.
Step-by-step explanation:
In the case of the first expression: x³ * x³ * x³, you will solve the power first, before multiplying the whole numbers.
However, in terms of the second one, you are multiplying the powers first, and then solving for the power.
Take for example, x = 2. Plug in 2 for x in the expressions given:
x³ * x³ * x³ = 2³ * 2³ * 2³ = 8 * 8 * 8 = 64 * 6 = 512
However,
2^(3 * 3 * 3) = 2^(27) = 134,217,728

( velocity - on a graph )
Answer:
a) v_avg = k
b) 0.034 km/h
Step-by-step explanation:
a) The average velocity is given by the displacement over the time:
[tex]v_{avg}=\frac{\Delta x}{\Delta t}[/tex] (1)
Δx is the area under the line. In this case you can consider two areas. Firs, from t=0 t0 t=30 and from t=30 to t=50:
S1 = 30k
S2 = 20k/2 = 10k
Then, the total surface is:
S = S1+S2 = 50k
The average speed is:
v_avg = (50k)/(50s)= k
b) The value of k can be determined by using the expression for the total area under the line, which is the total displacement of the car S=1.7 km:
S=50k=1.7km
k=(1.7km)/(50k)=0.034km/h = 34 m/h

Answer:
8400
Step-by-step explanation:
Round them to their nearest whole:
23.8 x 349
24 x 350
We then use what we rounded and answer...
24 x 350 estimated to 8400
Answer:
6000
Step-by-step explanation:
23.8 - 20
349 - 300

Step-by-step explanation:
............
In triangle ABC angle a equals 72° side C equals 61 and angle B equals 16° find side a to the nearest 10th
Answer:
58.0 units
Step-by-step explanation:
In order to use the law of sines, we need to know angle C. It will be the angle that brings the total of all angles to 180°.
C = 180° -A -B = 180° -72° -16°
C = 92°
The law of sines tells us ...
a/sin(A) = c/sin(C)
a = c·sin(A)/sin(C) = 61·sin(72°)/sin(92°)
a ≈ 58.0 . . . . units
it took 4 hours to clean 10 houses, how many houses could be cleaned in 8 hours?
Answer:
3 1/2 houses
Step-by-step explanation:
To find the unit rate we must divide 4 by 10
4 hours divided by 10 house = 1/4
1/4 houses per hour
8 hours times 0.4= 3.2 houses
Answer:
20 houses
Step-by-step explanation:
Let’s make a proportion using this setup:
houses/hours=houses/hour
We know that 10 houses can be cleaned in 4 hours. We don’t know how many houses can be cleaned in 8 hours, so we can say x houses can be cleaned in 8 hours.
10 houses/4 hours= x houses/8 hours
10/4=x/8
Now we have to solve for x, by getting x by itself. Perform the opposite of what is being done to both sides.
x is being divided by 8. The opposite of division is multiplication, so multiply both sides by 8
8(10/4)=(x/8)8
8(10/4)=x
8(2.5)=x
20=x
20 houses can be cleaned in 8 hours.

The value of a certain car decreases by 16% each year. What is the 1⁄2-life of the car?
Answer:
The half life of the car is 3.98 years.
Step-by-step explanation:
The value of the car after t years is given by the following equation:
[tex]V(t) = V(0)(1-r)^{t}[/tex]
In which V(0) is the initial value and r is the constant decay rate, as a decimal.
The value of a certain car decreases by 16% each year.
This means that [tex]r = 0.16[/tex]
So
[tex]V(t) = V(0)(1-r)^{t}[/tex]
[tex]V(t) = V(0)(1-0.16)^{t}[/tex]
[tex]V(t) = V(0)(0.84)^{t}[/tex]
What is the 1⁄2-life of the car?
This is t for which V(t) = 0.5V(0). So
[tex]V(t) = V(0)(0.84)^{t}[/tex]
[tex]0.5V(0) = V(0)(0.84)^{t}[/tex]
[tex](0.84)^{t} = 0.5[/tex]
[tex]\log{(0.84)^{t}} = \log{0.5}[/tex]
[tex]t\log{0.84} = \log{0.5}[/tex]
[tex]t = \frac{\log{0.5}}{\log{0.84}}[/tex]
[tex]t = 3.98[/tex]
The half life of the car is 3.98 years.

Hey there!
When we have negative numbers, we might count like this: ....-5,-4,-3,-2,-1,0,1,2,3....
As you can see, the negative number is known as greater if it is closer to zero, so -1 is greater than -100.
With this information, let's order these numbers! :)
-10,-9,-8,-7,-6,-5,-4,0,2,9,10

In a right triangle, the measure of theta = 43 degrees and the side opposite to the measure of theta is 6.5 cm long. The length of the side adjacent to the measure of theta is approximately
We have been given that in a right triangle, the measure of [tex]\theta = 43^{\circ}[/tex] and the side opposite to the measure of theta is 6.5 cm long. We are asked to find the length of adjacent side to the angle theta.
We know that tangent relates opposite side of right triangle adjacent side.
[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]
[tex]\text{tan}(43^{\circ})=\frac{6.5}{\text{Adjacent}}[/tex]
[tex]\text{Adjacent}=\frac{6.5}{\text{tan}(43^{\circ})}[/tex]
[tex]\text{Adjacent}=\frac{6.5}{0.932515086138}[/tex]
[tex]\text{Adjacent}=6.9703966[/tex]
[tex]\text{Adjacent}\approx 6.97[/tex]
Therefore, the length of adjacent side to angle theta is approximately 6.97 units.

Answer:
a) the co-ordinates of the center are (-3,4) and the length of the radius is 10 units
Center (h,k) = (-3 ,4) and radius 'r' = 10
Step-by-step explanation:
Step(i):-
Given circle equation is
[tex]2 x^{2} +12 x+2 y^{2} -16 y-150 =0[/tex]
Dividing "2' on both sides, we get
[tex]x^{2} +6 x+ y^{2} -8 y-75 =0[/tex]
Step(ii):-
now
[tex]x^{2} +2(3x) + (3)^{2}-(3)^{2} +y^{2} -2 (4 y)+(4)^{2}-(4)^2 -75 =0[/tex]
by using (a+b)² =a²+2 a b+b²
(a-b)² =a²-2 a b+b²
[tex](x+3)^{2}-(3)^{2} +(y-4)^{2}-(4)^2 -75 =0[/tex]
[tex](x+3)^{2}-9 +(y-4)^{2}-16 -75 =0[/tex]
[tex](x+3)^{2} +(y-4)^{2}-100 =0[/tex]
[tex](x+3)^{2} +(y-4)^{2}=100[/tex]
[tex](x+3)^{2} +(y-4)^{2}=(10^2)[/tex]
by comparing
[tex](x-h)^{2} +(y-k)^{2}=(r^2)[/tex]
Final answer:-
Center (h,k) = (-3 ,4) and radius 'r' = 10

Step-by-step explanation:
The coach of a college basketball team records the resting pulse rates of the team's players. A confidence interval for the mean resting pulse rate of all collegians based on these data is of little use because __________.
A) the sample size is small, so the margin of error will be large.
B) the members of the basketball team can't be considered a random sample from the entire collegiate population.
C) many of the students on the team may refuse to respond.
D) the coach has sampled the entire population so there is no need for inference.
Answer:
B) the members of the basketball team can't be considered a random sample from the entire collegiate population.
Step-by-step explanation:
The coach is trying to estimate a parameter of a population (the mean resting pulse rates of alla collegians) from a sample statistic (the mean resting pulse of the basketball team's players).
The confidence interval for the parameter is of little use as the sample of team players is not representative of the population of collegians. The sample can not be considered random. Then, the estimation of the parameter will be biased.

Susan paid $240 to have her house decorated. The materials used to decorate the house coast $115, and service was charged at $5 an hour. How many hours was the house worked on?
Answer:
[tex] 240 =5x +115[/tex]
And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:
[tex] 240-115= 5x[/tex]
[tex] 125 = 5x[/tex]
And now we can divide both sides by 5 and we got:
[tex] x= 25[/tex]
So then the number of hours spent to decorate the house are 25
Step-by-step explanation:
Based on the information given we can model this function with this formula:
[tex] y = mx+b[/tex]
Where y represent the total cost paid, m the cost per hour representing the slope and x the number of hours worked and finally b the initial cost for the materials. Then our function is given by:
[tex] 240 =5x +115[/tex]
And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:
[tex] 240-115= 5x[/tex]
[tex] 125 = 5x[/tex]
And now we can divide both sides by 5 and we got:
[tex] x= 25[/tex]
So then the number of hours spent to decorate the house are 25
