The first one is done and the options for number four are:
w(2w+12)=160
2w^2+12w-260=0
2w^2+12w=260
w^2+6w-130=0
Answers
Answer:
Step-by-step explanation:
Part A
w² + 6w + c = 130 + c
w² + 2(3w) + c = 130 + c
To make left side of the equation a perfect square we will replace c by (3)².
w² + 2(3w) + 3² = 130 + c
[By formula → a² + 2ab + b² = (a + b)²]
w² + 2(3w) + 9 = 130 + 9
Therefore, c = 9 will be the answer.
Part B
From part A,
(w + 3)² = 139
Option (2) and Option (6) are the correct options.
Part C
w + 3 = √139
w = 11.79 - 3
w = 8.79
w ≈ 8.8 inches

Two functions are shown below
f(x)=8x+10
g(x)=6x-4
What is f(4)-g(3)?
Answers
Answer:
c.28
Step-by-step explanation:
Given
f(x) = 8x + 10 and g(x) = 6x - 4
f(4) = 8*4 + 10
= 32 + 10
= 42
g(3) = 6 * 3 - 4
= 18 - 4
= 14
Now
f(4) - g(3)
= 42 - 14
=28
hope it will help :)
f(4)= 8(4)+10= 42
g(3)= 6(3)-4= 14
f(4)- g(3)= 42-14= 28

Harold is moving a 5- foot tall refrigerator. He tilts it onto its rear edge forming an angle between the back of the refrigerator and the floor; the top edge of the tilted refrigerator is exactly 4 feet above the floor as shown in the following diagram.
What is the cosine of the angle the refrigerator makes with the floor?
A, 4/5
B, 5/4
C, 4/3
D, 3/4
E, 3/5
Please help I’ll give branliest
Answers
The cosine of the angle the refrigerator makes with the floor is option (E) 3/5 is the correct answer.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
Harold tilted the 5 foot fridge, so the slanting height = 5 feet
The tilted refrigerator makes the height 4 feet from the floor.
From the diagram,
The three sides of the triangle according to Pythagoras theorem are
Hypotenuse side, h = 5 feet
Opposite side, o = 4 feet
Let a be the adjacent side.
By Pythagoras theorem,
[tex]Hypotenuse^{2} = Opposite^{2}+Adjacent^{2}[/tex]
⇒ [tex]5^{2} =4^{2} +a^{2}[/tex]
⇒ [tex]a^{2} = 25-16[/tex]
⇒ [tex]a=\sqrt{9}[/tex]
⇒ [tex]a=3[/tex]
Thus the trigonometric ratio cosine of the angle is
[tex]cos \theta =\frac{Adjacent}{Hypotenuse}[/tex]
⇒ [tex]cos \theta =\frac{3}{5}[/tex]
Hence we can conclude that the cosine of the angle the refrigerator makes with the floor is option (E) 3/5 is the correct answer.

A sport store pays its wholesaler $40 for a baseball bat, and then sells it to a customer for $76. What is the markup rate?
Answers
Answer:
Markup 90%
Step-by-step explanation:
If $40 is 100% of the price
then
$76 is ..........x
Cross multiplication
40(x) = 76(100)
40x = 7600
Divide by 100
x = 190
190% = 100% + 90%
That means that the price is the whole price(100%) plus 90%
so the markup is 90%
ANOTHER WAY:
The difference in prices is $76-$40=$36. So, we need to find what percentage of 40 is 36.
We do this by dividing: 36/40=0.9, which is 90%. So, the markup is 90%.

It has only one horizontal asymptote.
D.
It has no vertical asymptote.
E.
It has no horizontal asymptote.
Answers
Answer:
tha anser us B
Step-by-step explanation:
it is very easy you just read the question carefully
The correct statement about the asymptotes of the function is it has only one horizontal asymptote.
What is Polynomial?Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables
If the degree of the polynomial function in the numerator of a rational function is 1 and the degree of the polynomial function in the denominator is 2, then the rational function can be written as:
f(x) = (ax + b)/(cx² + dx + e)
The leading coefficient of the numerator is a, and the leading coefficient of the denominator is c. Therefore, the function has one horizontal asymptote given by y = a/c.
Thus, the correct statement about the asymptotes of the function is it has only one horizontal asymptote.

Step-by-step explanation:
dn means the difference (meaning what do you add/subtract to get the next number)
T0 means the term before the first one you got.
Tn = dn + T0
Tn = 2n + 0

Tn = 2n

An= 2n
