Simplify each of the following.
7^2 x 7^3
9514 1404 393
Answer:
7^5 = 16,807
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
__
Here, we have a=7, b=2, c=3, so ...
(7^2)(7^3) = 7^(2+3) = 7^5 = 16,807

Jacob has $100 in his savings account. The interest rate is 5% per year. How much interest will he earn in 1 year?
Triangle A'B'C' is the image of triangle ABC after a sequence of rigid motions,
Answer:
The sequence are:
i. reflection about the y-axis
ii. 2 units translation downwards
iii. 1 unit translation to the right
Step-by-step explanation:
Rigid transformation is a process of producing the image of a given figure or shape by either reflection, rotation, dilation or translation method. Thus the orientation and size of the figure changes with respect tot the method applied.
For the given question, some sequence were applied to produce the image of ABC.
The sequence are:
i. reflection about the y-axis
ii. 2 units translation downwards
iii. a unit translation to the right
A line passes through point (-2, 5) and has a slope of 5/2.
Write an equation in Ax + By = C form for this line.
Use integers for A, B, and C.
Answer:
5x-2y=-20
Step-by-step explanation:
y-y1=m(x-x1)
y-5=5/2(x-(-2))
y-5=5/2(x+2)
y-5=5/2x+10/2
y-5=5/2x+5
y=5/2x+5+5
y=5/2x+10
y-5/2x=10
-5/2x+y=10
2(-5/2x+y)=2(10)
-10/2x+2y=20
-5x+2y=20
5x-2y=-20
A certain population is initially 8,951 but declines by 8% every second. Find an exponential formula that gives the population as a function of time. What will be the population after half of a minute?
9514 1404 393
Answer:
734
Step-by-step explanation:
The growth factor is 1 -8% = 0.92. This is the base of the exponential formula. The multiplier is the initial value, so you have ...
p = 8951×0.92^t
When t=30, this evaluates to ...
p = 8951×0.92^30 ≈ 733.68
The population after half a minute will be about 734.

Kamila buys a notebook for $1.59 and pens for $0.29 each. She spends $5.07.
Define a variable that can be used to determine how many pens she bought.
Write an equation using the variable and solve to determine how many pens she bought.
Answer:
12 pens
Step-by-step explanation:
Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.
Price of a notebook = $1.59
Price a pen = $0.29
Total amount spent = $5.07
But,
1.59 + 0.29 n = 5.07
So that,
0.29 n = 5.07 - 1.59
0.29 n = 3.48
n = [tex]\frac{3.48}{0.29}[/tex]
= 12
Therefore, Kamila bought 12 pens.

Which equation would you use to solve this problem: Laura bought 4 1/3 bushels of apples for $16. How much did each bushel cost? *
Answer: $3.69
Step-by-step explanation:
Laura bought 4 1/3 bushels of apples.
Firs convert this to an improper fraction for easier calculation:
= 13/3 bushels of apples.
If cost $16 altogether, individually they must cost:
= Cost / Quantity purchased
= 16 ÷ 13/3
= 16 * 3/13
= $3.69
Note: You can divide by a fraction by multiplying the inverse of that fraction.
Expand: f(x)= x^4- x^3+x^2+x-

Vertical angles are a pair of opposite angles made by two intersecting lines and the angles are _________. *
2 points
Equal to each other
Equal to 90°
Equal to 180°
Equal to 360°
Answer:
[tex] \boxed{ \large{ \underline{\tt{Equal \: to \: each \: other}}}}[/tex]
Step-by-step explanation:
When two lines interesect , the angles formed opposite to each other are called vertically opposite angles. Vertically opposite angles [ V.O.A ] are always equal to each other.
Refer to the attachment! In the given figure , [tex] \angle[/tex] p and [tex] \angle[/tex] s are opposite to [tex] \angle[/tex]r and [tex] \angle[/tex]q respectively. Therefore [tex] \angle[/tex]p and [tex] \angle[/tex]r are vertical angles. Similarly , [tex] \angle[/tex]s and [tex] \angle[/tex]q are also vertical angles.
Hence , Our final answer : Vertical angles are a pair of opposite angles made by two intersecting lines and the angles are equal to each other .

At the circus, a clown is shot from a cannon. This situation can be modeled by the function: h = – 16t2 + 45t + 15, where 'h' is height in feet and 't' is time in seconds. Height of the clown
Answer:
t = 3.11 seconds
Step-by-step explanation:
Given that,
At the circus, a clown is shot from a cannon. This situation can be modeled by the function :
[tex]h = -16t^2 + 45t + 15[/tex]
Where
'h' is height in feet and 't' is time in seconds
We need to find how long did it take for the clown to reach his highest point. It can be calculated as follows :
[tex]-16t^2 + 45t + 15=0[/tex]
We need to solve for t. It can be calculated as follows :
[tex]t=\dfrac{-45\pm \sqrt{45^2-4(-16)(15)} }{2(-16)}\\\\t=-0.301\ \text{and}\ 3.11\ s[/tex]
So, the required time is 3.11 seconds.

There are two right angle triangles, triangle ABC and Triangle EDF. Measure of angle ACB and angle EFD are 90. Side AB is congruent to side ED, Side AC is congruent to side DF. What theorem can be used to show that ABC ≅ DEF?
Answer:
SAS theorem
Step-by-step explanation:
Given
Triangles ABC and DEF
[tex]AB = ED[/tex]
[tex]AC = DF[/tex]
[tex]\angle ACB = \angle EFD = 90^{\circ}[/tex]
Required
Which theorem shows the similarity between both triangles
The following can be deduced from the given parameters.
[tex]AB = ED[/tex] ===> Equal Sides
[tex]AC = DF[/tex] ===> Equal Sides
[tex]\angle ACB = \angle EFD = 90^{\circ}[/tex] ===> Equal Angle
This implies that two sides and 1 angle of both triangles are equal.
Hence, the theorem to use is the SAS theorem.

Answer:
Pair 1: GM and LJ
Pair 2:HI and LM
Step-by-step explanation:
The markings on the line show which lines are congruent to each other. This means that line HI and ML are congruent because they have similar markings. And you could say the same for line JL and MG because it has 2 lines that mark it as congruent to eachother.
So basically your answers are GM and LJ as one pair and HI and LM as another
