Martina is currently 12 years older than her cousin Joey. In 4 years she will be 3 times as old as Joey. Use this information to answer the following questions.
Step 1 out of 6:
Analyze Information
The goal is to find Martina's age and Joey's age.
Formulate a Plan
Use an equation to find Martina's age and Joey's age.
Solve
Write the equation 3(x + 4) = x + _____, where x is Joey's age.
Joey is 2 years old now and Martina is 16 years old now.
Explanation:
You are comparing the ages of two people and at two different periods of time - the present and in 5 years time.
Let the present age of the younger cousin (Joey) be
x
years.
Martina is 14 years older now. Her age is
(

14
)
years
In 5 years time , they will both be 5 years older than they are now:
Joey will be

write y=-2x^2-20x-52 in vertex form then find the axis of symmetry. show your work!
Answer:
Simplifying
y = 2x2 + 20x + 52
Reorder the terms:
y = 52 + 20x + 2x2
Solving
y = 52 + 20x + 2x2
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 52 + 20x + 2x2

Step-by-step explanation:
Question 10: ([tex]\frac{1}{2}[/tex] * 4)([tex]\frac{1}{2}[/tex] * 2)([tex]\frac{1}{2}[/tex] * 2) = 2 * 1 * 1 = 2[tex]cm^{3}[/tex]
Question 11: ([tex]\frac{1}{3}[/tex] * 4)([tex]\frac{1}{3}[/tex] * 2)([tex]\frac{1}{3}[/tex] * 1) = [tex]\frac{4}{3}[/tex] * [tex]\frac{2}{3}[/tex] * [tex]\frac{1}{3}[/tex] = [tex]\frac{8}{27}[/tex][tex]cm^{3}[/tex]

The illustration below shows the graph of y as a function of x.
Complete the following sentences based on the graph of the function.
- As x increases, y _______ (increases/decreases).
- The rate of change for y as a function of x is not __________ (constant/constant), therefore the function is ________ (linear/nonlinear).
- For all values of x, the function value y ___ (≤/≥/=) 0.
- The y-intercept of the graph is the function value y = ____.
- When x = 1, the function value y = ___.
Answer: As "x" increases "y" *decreases*
y as a function of x is not *constant*
Therefore the function is *nonlinear*
For all values of x, the function value y *≥* 0.
The y intercept of the graph is *8*
x=1 function value of y is *5*
The given function is an exponential function and its qualities are explained below.
What is a logarithmic function?The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.
As we can observe in the graph.
The illustration below shows the graph of y as a function of x.
Complete the following sentences based on the graph of the function.
- As x increases, y decreases.
- The rate of change for y as a function of x is not constant, therefore the function is nonlinear.
- For all values of x, the function value y > 0.
- The y-intercept of the graph is the function value y = 8.
- When x = 1, the function value y = 5.

Answer:

Answer: LCD = 72
Step-by-step explanation:
Rewriting input as fractions if necessary:
1/8, 1/12, 7/18
For the denominators (8, 12, 18) the least common multiple (LCM) is 72.
LCM(8, 12, 18)
Therefore, the least common denominator (LCD) is 72.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1/8 = 1/8 × 9/9 = 9/72
1/12 = 1/12 × 6/6 = 6/72
7/18 = 7/18 × 4/4 = 28/72

find the length of of a 100-yard football field in meters. Use 1 yard = 3 feet
and 1 meters ≈ 3.28 feet round to the nerest tenth.
(≈ means about)
Answer: 91.46m
Step-by-step explanation: The length of 100 yard football field in meters. From the dimension given, 1 yard = 3 feet Therefore, 100 yard = x feet 1 yard = 3 feet 100 yard = x feet X = (100 × 3) / 1 X = 300 feet. But, 1 meter = 3.28feet X meter = 300 feet X = (300 × 1) 3.28X = 91.46m Therefore, 100 yard football field is equal to 91.46m

Write your own real-world scenario where the Pythagorean Theorem can be applied to find a missing piece. You may choose to write a problem that is two- or three-dimensional in nature. Be sure that you will be able to draw a diagram of your scenario.
Write out your problem and submit it for Part 1. Be sure to end your scenario with a question.
Answer:
Supposed that you needed to know the diagonal distance from opposite corners of a rectangular prism.
d^2=x^2+y^2+z^2 where x, y, and z are the dimensions of the prism, or rectangular "box"
If the box has a width of 10, depth of 20, and a height of 30 then you have:
d^2=100+400+900
d^2=1400
d^2=100*14
d=√(100*14)
d=10√14 units
d≈37.42 units (to nearest hundredth of a unit)
You might need this information to determine the most amount of space necessary to allow this box to pass through in any orientation...as the diagonal is the maximum dimension of the box.
I did a three-dimensional problem as the Pythagorean Theorem is often used only for two-dimensional problems in early mathematics.
