When we decrease the exponent of 10 by 1, the number becomes one-tenth of the previous number.
For the fixed base(10), if the exponent decrease by 1, the number will becomes one-tenth of the previous number.
What are the rules of exponents?The Power Rule for Exponents is (a^m)^n = a^m*n. To increase a number with an exponent to a power, we need to multiply the exponent times the power. Negative Exponent Rule is x^-n = 1/x^n. We need to invert the base to change a negative exponent into a positive.
Exponents are used to represent repeated multiplication of a number by itself. For example, 7 * 7 * 7 can be showed as 73. Here, the exponent is 3 that stands for the number of times the number 7 is multiplied. The base here is 7 that is the actual number which is getting multiplied. So, initially exponents or powers shows the number of times a number can be multiplied. If the power is 2, it means the base number is multiplied two times with itself.

In a tennis tournament, 25% of Sarah’s serves were aces. Design a simulation to predict how many aces you expect Sarah to serve out of 50 serves
Answer:
about 13 aces
Step-by-step explanation:
.25 x 50= 12.5
25% is equal to .25, you are trying to find 25% of 50. Of means multiple,
so how you get the equation .25 x 50, you can't have half a serve so you round up to 13 aces
Use the discriminant to determine all values of k which would result in the graph of
the equation y = -2x2 + kx – 18 being tangent to the x-axis.
Answer:
k = ±12
Step-by-step explanation:
Equation of the graph is,
y = -2x² + kx - 18
Discriminant of a quadratic equation, y = ax² + bx + c is defined by
Discriminant = √(b²- 4ac)
If √(b²- 4ac) = 0,
Equation will have one real solution.
Discriminant of the the given equation = √[k² - 4(-2)(-18)]
Since, graph of the equation is tangent to the x-axis, there will be one real solution.
Therefore, √[k² - 4(-2)(-18)] = 0
k² - 144 = 0
k = ±√144
k = ±12

which statement is true
Answer:
The correct answer would be C Reason being the same angle stays the same after the rotationWrite as a fraction and fractional model model: there is one container of fruit juice and 2 people want juice
Question seems incomplete but we would make assumptions in order to answer and explain
Answer and explanation:
If we wish to model this situation in the form of a fraction: there is one container containing 30 cans of fruit juice and 2 people want fruit juice, we would be finding how many fruit juice each person would get from the container.
Given one container= 30 cans of fruit juice
Number of persons that require fruit juice = 2
Therefore fraction of fruit juice in relation to required fruit juice= 30/2

The coordinate bridge shows the cost of different numbers of bookmarks how many sense do for bookmarks cost.
Answer:
54 cents
Step-by-step explanation:
The cost of bookmarks relating to the number of bookmarks is given by the graph shown. Therefore:
From the graph, we can determine the relationship between the cost of bookmarks and the number of bookmarks by using two points. The equation of a line passing through points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\[/tex]
From the graph, y represents the cost of bookmarks in cents and x represent the number of bookmarks. we can see that it passes through the point (2, 30) and (7, 90). Hence:
[tex]y-30=\frac{90-30}{7-2}(x-2)\\\\y-30=12(x-2) \\\\y-30=12x-24\\\\y=12x+6[/tex]
The cost of 4 bookmarks (x = 4):
y = 12(4) + 6
y = 54 cents

Dan is stocking up on AA and AAA batteries. He bought 10 packages of batteries for a total of 72 batteries. The AA batteries are sold in packages of 6, and the AAA batteries are sold in packages of 8. Write, but do not solve, a system of equations that can be used to find how many packages of each type of battery Dan bought.
Answer:
x + y = 10
6x + 8y = 72
Step-by-step explanation:
Number of packages = 10
Total batteries = 72
For AA:
batteries per package = 6
Let number of packages = x
For AAA:
batteries per package = 8
Let number of packages = y
Number of AA packages + number of AAA packages = 10
Sum of AA + sum of AAA equals 72 batteries
x + y = 10
6x + 8y = 72
Answer:Answer:
x + y = 10
6x + 8y = 72
Step-by-step explanation:
Number of packages = 10
Total batteries = 72
For AA:
batteries per package = 6
Let number of packages = x
For AAA:
batteries per package = 8
Let number of packages = y
Number of AA packages + number of AAA packages = 10
Sum of AA + sum of AAA equals 72 batteries
x + y = 10
6x + 8y = 72

A 20 feet tree casts a shadow that is 32 feet long. What is the distance from the top of the tree to the tip of the shadow?
Answer:
37.7359
Step-by-step explanation:
first you visualize the shape created
if you visualize it... it will look like a right angled triangle
and we are looking for the longest side
remember the pythagoras theorem c^2= a^2 + b^2
in this case we are looking for c
a^2= 20^2
b^2= 32^2
400+ 1024= 1424
therefore c^2= 1424
then you square root 1424
to get 37.7359
