Simple Interest Rate Formula: A = P(1 + rt)
P is principle amountr is ratet is timeStep-by-step explanation:
Step 1: Define
Identify
P = 80
r = 2% = 0.02
t = 5
Step 2: Find Interest
Substitute in variables [Simple Interest Rate Formula]: A = 80(1 + 0.02 · 5)(Parenthesis) Multiply: A = 80(1 + 0.1)(Parenthesis) Add: A = 80(1.1)Multiply: A = 88Write x^2 + 4x +5 in the form of (x + a)^2 + b where a and b are integers
Answer:
[tex](x+2)^2 + 1 \ , \ where \ a = 2 \ , \ b = 1[/tex]
Step-by-step explanation:
[tex](x + 2)^2 = x^2 + 4x + 4\\\\(x+2)^2 + 1 = x^2 + 4x + 5[/tex]
[tex]Therefore,[/tex]
[tex]x^2 + 4x + 5 = (x+2)^2 + 1[/tex]
If n is an even number, find the next consecutive even number.
Answer:
n+2 is the next even number as n is an even number so adding 2 will make it an even number again.
what is an expression showing the sum of 5 less than the number k
Answer:
5<k
Step-by-step explanation:
Answer:
k-5
Step-by-step explanation:
So, lets go over each part of the sentence, and turn it into a expression.
So it first says sum. This means addition, so we can start our expression with:
+
Next is says of 5. So we know its the addition of 5:
+5
Next it says less than. So now we know less than, which is subtraction. So we can swap the addition sign for a - sign:
-5
Finally it says the number k. So we know that the subtracted value is k:
k-5
So this is your expression!
Hope this helps!

Bart is collecting data on sunflower growth. He records the height, in inches, of his sunflower each day. Which best describes the type of data Bart is collecting
Answer:
Numerical data
Step-by-step explanation:
Given
Height recorded on a bar chart
Required
The type of data
From the question, we understand that the height is being recorded.
Height of flowers are numbers (e.g. 6in, 5in. 3in etc.).
When data are presented in numbers (i.e. digits), such data are referred to as numerical data.

What is the axis of symmetry for the function f(x)=7−4x+x2?
x = –3
x = –2
x = 2
x = 3
Answer:
Answer:
x = 2
Step-by-step explanation:
The vertex form of the parabola is given by
Comparing this equation with vertex form of a parabola , where (h,k) is the vertex
h = 2
k = 3
Hence, vertex is (2,3)
Now, axis of symmetry of a parabola passes through the vertex and divide the parabola in two equal halves.
Hence, axis of symmetry of the parabola is given by
x = h
x = 2

The straight line 3x + 4y = 24 cuts the y - axis at the point A and cuts the x - axis at the point B. What is the distance AB?
Step-by-step explanation:
the answer is in the above image
The distance between point A and point B is 10 units.
What is the distance between two points on a plane?The distance between two points on a coordinate plane (x, y) and (x, y) is
= √[(x₂ - x₁)² + (y₂ - y₁)²] units
The given straight line is 3x + 4y = 24.
This straight line will cut the x-axis at a point where y = 0.
Therefore, 3x + 4(0) = 24
⇒ 3x = 24
⇒ x = 8
Therefore, the coordinates of the point A is (8, 0).
Similarly, this straight line will cut the y-axis at a point where x = 0.
Therefore, 3(0) + 4y = 24
⇒ 4y = 24
⇒ y = 6
Therefore, the coordinates of the point B is (0, 6).
Therefore, the distance between point A and point B is
= √[(0 - 8)² + (6 - 0)²] units
= √(64 + 36) units
= √100 units
= 10 units (negative sign is avoided.)

Taxi company A charges $4 plus $2 per mile. Taxi company B charges $5 plus $3 per mile. Which system best represents this problem?
y = 4 x + 0 . 5 , y = 5x + 0.25
y = 4 + 2x , y = 5+3x
y = 4 x + 1 5 , y = 15x + 2
y = - 0 . 5 x + 4 , y = -0.25x + 5
Answer:
The second option
Step-by-step explanation:
To solve this, you should convert both rates to equations, with y being the total fare, and x being the number of miles. The rates of both use the format y=mx+b (where m is the amount per mile and b is the flat rate, or original rate).
By subbing in the values for m and b, you get y=2x+4 for A and y=3x+5 for B. This is the second option.

Write the equation in standard form for the circle x2 + 32 = -y² + 12x.
Step-by-step explanation:
Move
26
to the right side of the equation because it does not contain a variable.
3x2−12x−2y2+16y=26
Answer:
(x - 6)² + y² = 4
Step-by-step explanation:
x² + 32 = -y² + 12x
Rearrange
x² - 12x + y² = -32
Complete the square for x
(x - 6)² + y² = -32 + (-6)²
(x - 6)² + y² = -32 + 36
(x - 6)² + y² = 4

Answer:
The correct answer is -
1. An image with correct tally marks and frequency values is attached.
2. Silver
Step-by-step explanation:
The given data of different color cars that going past his house one morning is given in 20 times. The frequency of each car is -
Blue cars - 4 times out of 20
red - 6 times out of 20
silver - 8 times out of 20
black - 2 times out of 20

Answer:
Step-by-step explanation:
[tex]F = \frac{9}{5}C+32[/tex]
Subtract 32 from both sides
[tex]F-32= \frac{9}{5}C\\[/tex]
Multiply both side by 5/9
[tex]\frac{5}{9}(F-32)=( \frac{5}{9})* \frac{9}{5}C\\\\ \frac{5}{9}(F-32)=C\\[/tex]
F= 41
[tex]\frac{5(41-32)}{9}=C\\\\ \frac{5*9}{9}=C\\\\ \frac{45}{9}=C\\\\C = 5\\\\[/tex]

Need quick help with this math
Answer:
A. 25/33
B. 1/3
C. 1/33
D. 25/9
Answer:
[tex]\text{A. }25/33,\\\text{B. }1/3, \\\text{C. }1/33, \\\text{D. }25/9[/tex]
Step-by-step explanation:
Recall that [tex]\frac{x}{9}=0.\overline{x}[/tex] for [tex]x\in (1, 8)[/tex]. If multiple digits are repeating, increase the number of nines in the denominator as applicable.
Therefore, we have:
Part A:
"75" is repeating:
[tex]\rightarrow \frac{75}{99}=\boxed{\frac{25}{33}}[/tex]
Part B:
"3" is repeating:
[tex]\rightarrow \frac{3}{9}=\boxed{\frac{1}{3}}[/tex]
Part C:
"03" is repeating:
[tex]\rightarrow \frac{03}{99}=\frac{3}{99}=\boxed{\frac{1}{33}}[/tex]
Part D:
"7" is repeating, but there is a terminating decimal 2.0 with it ([tex]2.\overline{7}=2.0+0.\overline{7}[/tex]):
[tex]2+\frac{7}{9}=\frac{18}{9}+\frac{7}{9}=\boxed{\frac{25}{9}}[/tex]
