Factorize the following:
49x² - 25
Answer:
(7x+5)(7x-5)
Step-by-step explanation:
We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.

What are exponential functions?When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function. There usual form is specified below. They are written in several such equivalent forms.
For example, [tex]y = a.b^x[/tex] , where a is a and b are constants is an exponential function.
How to calculate simple interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:
[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]
The final amount becomes:
[tex]A = CI + P\\A = P(1 +\dfrac{R}{100})^T[/tex]
Usually these two rates are used on money. The compound interest is exponential as it has power T as a variable, but for simple interest, there is no variable exponent.
Both are positive, and growth of exponential function is always going to surpass the growth of linear function (can be proven by derivatives).
Since we are not given the function's equation, we cannot correctly calculate the value just from graph, but as in 14 years, the blue line is already close to red line so it will likely cross it after 6 more years (thus total 20 years) because of good growth.
Thus, the person who will have more money by year 20 is given by: Option C: Tyler, because his money is increasing exponentially

The perimeter of a rectangle is
30m. The length of the rectangle is
3 m more than twice the width. Find
the dimensions of the rectangle
a. 3m x 12m
b 4m x 11m
c 8m x 7m
d 6m x 9m
Equation for Perimeter of a rectangle: Perimeter = 2W + 2L
Defining the variables, let
Width = xLength = 2x+3 (3 more than twice the width)
Plugging everything into the equation
30= 2(x) + 2(2x+3) using the distributive property,30=2x+4x+6 combining like terms30=6x+6 subtracting 6 from both sides,24=6x divide both sides by 64=x This means that the width is 4 m.To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved forL=2(4)+3L=8+3 = 11 m
So the dimensions of the rectangle are width is 4 m and length is 11 m.
The Boston Red Sox had 949 runs in their 2004 season. In their 2015 season, they had 748 runs. Find the rate of change in runs.
Answer: -18.27 per year
Step-by-step explanation:
The difference in years is:
= 2015 - 2004
= 11 years
In those 11 years, the runs decreased from 949 to 748.
The total decrease is:
= 949 - 748
= 201 runs
The rate of change is:
= 201 / 11
= 18.27 per year
Since it is reducing, the rate is:
= -18.27 per year
Which of the following best classifies a quadrilateral with coordinates A(7,0), B(3, 1), C(4,7), and D(8, 6)?
A.Rectangle
B.Parallelogram
C.Trapezoid
D.Square
Answer:
B. Parallelogram
Step-by-step explanation:
The opposite sides of the quadrilateral are equal and so the quadrilateral is a rectangle, the correct option is A.
What is a Quadrilateral?A quadrilateral is a polygon with four sides.
The coordinates of a quadrilateral are:
A(7,0), B(3, 1), C(4,7), and D(8, 6)
The distance between the coordinates has to be determined to identify the type of quadrilateral
The distance formula is
[tex]\rm D = \sqrt { ( x- x_1)^2 + (y-y_1)^2}[/tex]
[tex]\rm AB = \sqrt { (3-7)^2 + (1-0)^2}\\AB = \sqrt { 17}[/tex]
[tex]\rm BC = \sqrt { ( 1)^2 + (6)^2}\\BC = \sqrt {37}[/tex]
Similarly,
[tex]\rm CD= \sqrt { 17}\\\\AD = \sqrt{37}[/tex]
The opposite sides of the quadrilateral are equal and so it is a rectangle.

The distance an object falls when dropped from a tower varies directly as the square of the time it falls. If the object falls 144 feet in 3 seconds, how far will it fall in 17 seconds? a 4046 ft b 272 ft c 4624 ft d 5202 ft answer is C
Answer:
the object will fall 792 feet in 17 seconds
Step-by-step explanation:
first you can do 144 multiplied by 5 because that would be 15 of those seconds next you would do 144 divided by 2 because you only need 2 seconds to reach 17 your answer would be 72 then you would do 720+72=792 so it would fall 792ft in 17 seconds
Step-by-step explanation:
Assuming the Height is denoted by "h" and the time by "t" , h=kt² since h varies as t².
When h=144ft , t=3
k=h/t²
k=144/3²
k= 16
This implies that h=16t² is the relation to be used.
Therefore when t= 17s, h=16*17²
h=4624ft

If

when
x
=
64
find,
x
when
y
=
8
Answer:
x = 49
Step-by-step explanation:
Given the mathematical expression and data;
y = 1/√x
y = 7 and x = 64
First of all, we would find the constant of proportionality, k;
y = k/√x
7 = k/√64
7 = k/8
k = 7 * 8
k = 56
Next, to find the value of x, when y = 8
y = k/√x
Substituting the values, we have;
8 = 56/√x
Cross-multiplying, we have;
8 * √x = 56
√x = 56/8
√x = 7
Taking the square of both sides, we have;
(√x)² = 7²
x = 49

Find the volume, given that the apothem is 11.3 in. (hint: remember for regular polygons, A = 2 (apothem) (Perimeter) Round your answer to the nearest - tenth.
Answer:
V = 3085 in³
Step-by-step explanation:
The volume is given by:
[tex] V = A*h [/tex]
Where:
A: is the area
h: is the height = 7 in
The area of the polygon can be found by using the given equation:
[tex] A = \frac{1}{2}a*p [/tex]
Where:
a: is the apothem = 11.3 in
p: is the perimeter
The perimeter is:
[tex] p = 13*6 = 78 in [/tex]
Hence, the volume is:
[tex] V = A*h = \frac{1}{2}a*p*h = \frac{1}{2}11.3 in*78 in*7 in = 3085 in^{3} [/tex]
