Somebody help me please
Answer:
see explanation
Step-by-step explanation:
given
(2x + 5)(2x - 1) ← expand using FOIL
(a)
= 4x² - 2x + 10x - 5 ← collect like terms
= 4x² + 8x - 5
(b)
using the method of completing the square on
4x² + 8x - 5 ← factor out 4 from the 1st 2 terms
= 4(x² + 2x) - 5
to complete the square
add/ subtract ( half the coefficient of the x- term )² to x² + 2x
= 4(x² + 2(1)x + 1 - 1) - 5
= 4(x + 1)² - 4 - 5
= 4(x + 1)² - 9
given the following geometric sequence: 1,3,9,27,81,...

Using the formula, find the 18th term of the sequence
Answer:
The 18th term of the geometric sequence is [tex]a_{18}=129140163[/tex]
Step-by-step explanation:
[tex]a_n=a_1(r)^{n-1}\\\\a_{18}=1(3)^{18-1}\\\\a_{18}=3^{17}\\\\a_{18}=129140163[/tex]

Write x2 - 2x - 3 = 0 in the form (x - a)2 = b, where a and b are integers. (1 point)
(x-4)2 = 3
(x-3) 2=2
(x-2)2= 1
O (x - 1)2 = 4
Answer:
4th option
Step-by-step explanation:
x² - 2x - 3 = 0 ( add 3 to both sides )
x² - 2x = 3
using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 3 + 1
(x - 1)² = 4
Match each transformation of function f to a feature of the transformed function.
By analyzing the parent function graph, we will see that:
1) m(x) = -f(x) ⇒ "function decreases as x increases"2) h(x) = f(x) + 2 ⇒ "asymptote of y = 2"3) j(x) = f(x + 2) ⇒ "y-intercept at (0, 4)"4) g(x) = 2*f(x) ⇒ "y-intercept at (0, 2)"What thing does each transformation?
Let's list each transformation and let's see which is the correct option for each one.
1) m(x) = -f(x).
This is a reflection over the x-axis, so, now the curve will open downwards. This means that now we have a decreasing function, so the correct option here is: "function decreases as x increases"
2) h(x) = f(x) + 2
This is a vertical translation of 2 units upwards. So it moves the whole graph 2 units upwards. Originally, you can see that in the left side we have an asymptote at y = 0, now that asymptote will be at y = 2.
So the correct option is: "asymptote of y = 2.
3) j(x) = f(x + 2)
This is a shift of 2 units to the left, notice that when we evaluate this in x = 0 we et:
j(0) = f(2) = 2^2 = 4
So the y-intercept os (0, 4).
4) g(x) = 2*f(x)
This is a vertical stretch of scale factor 2.
When we evaluate this in x = 0, we get:
g(0) = 2*f(1) = 2
So the y-intercept is at (0, 2).

A new fitness center opens with 120 members. Every month the fitness center increases the number of members by 40 members. How many members will the fitness center have after being open for 3 months?
Answer:
240 members
Step-by-step explanation:
Let y = total and x = no. of months
y = 40x + 120
= 40(3) + 120
= 120 + 120
= 240 members
Micha works at a sporting goods store. He is paid $8.25 per hour plus double time on holidays and makes an average of 8% commission on all golfing equipment sales.

An expression is defined as a set of numbers, variables, and mathematical operations. The gross pay of Micha for the given month is $234.71. The correct option is C.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given that Micha is paid $8.25 per hour plus double time on holidays and makes an average of 8% commission on all golfing equipment sales, which is modeled by the expression 8.25(x) + 8.25(2)(y) + 0.08(z).
Now, if Micha worked 15 regular hours and 4 holiday hours and had $562.00 in golf equipment sales. Therefore, the value of x, y, and z is,
Regular hours, x = 15
Holiday hours, y = 4
Sales made in dollars, z = 562
Substitute the values in the given expression to get the gross pay of Micha in the given year,
Gross pay = 8.25(x) + 8.25(2)(y) + 0.08(z)
= 8.25(15) + 8.25(2)(4) + 0.08(562)
= $123.75 + $66 + $44.96
= $234.71
Hence, the gross pay of Micha for the given month is $234.71.

This diagram shows a circle with an inscribed right triangle and some of its measurements in units.
Based on the diagram what is the circumference in units of the circle
Answer:
B
Step-by-step explanation:
the hypotenuse of the right triangle is the diameter d of the circle
Using Pythagoras' identity in the right triangle
d² = 6² + 8² = 36 + 64 = 100 ( take square root of both sides )
d = [tex]\sqrt{100}[/tex] = 10
the circumference (C) of a circle is calculated as
C = πd = π × 10 = 10π

Triangle ABC has angle measures as shown below. Using the information in the diagram, find the value of x.
In your answer, give the value of x and explain how you calculated it.
Solution:
The interior angles of a triangle sum up to 180°
This means that...
3(x + 2) + 52 + 35 = 180Simplify the distributive property.
3x + 6 + 52 + 35 = 180Combine like terms.
3x + (6 + 52 + 35) = 180=> 3x + (93) = 180Subtract 93 both sides.
3x + (93) = 180=> 3x + 93 - 93 = 180 - 93Simplify both sides.
=> 3x = 87Divide 3 both sides.
=> 3x/3 = 87/3 => x = 87/3 = 29Tim made 10 baskets during a basketball game. Each basket was worth either 2 or 3 points. How many different numbers could represent the total points scored by Jordan? What's the answer?
