Answer:
See explanation below for all parts
Step-by-step explanation:
Your current slope (m) is -1/2 (the orange colored slope) so the "opposite" slope would be 2/1 or 2(the blue colored slope)
The answer for number 3 is y=2x+b.
For number 4, plug in the point values for x and y and solve for b. The point given is (-4,-5).
-5=2(-4)+b Now simplify
-5=-8+b then add 8 to both sides to isolate b
3=b or b=3
For number 9, you now know that m is 2 and b is 3
y=2x+3
whats the slope of a line that runs through (-10,11) and (8,-5)
Answer: m = -8/9

A magazine provided results from a poll of 20002000 adults who were asked to identify their favorite pie. Among the 20002000 respondents, 1414% chose chocolate pie, and the margin of error was given as plus or minus±33 percentage points. What values do ModifyingAbove p with caretp, ModifyingAbove q with caretq, n, E, and p represent? If the confidence level is 9999%, what is the value of alphaα?
Answer:
Step-by-step explanation:
Given that:
The sample size n = 2000
The sample proportion [tex]\hat p[/tex] = 0.14
If [tex]\hat p[/tex] = 0.14, then [tex]\hat q[/tex] = 1 - [tex]\hat p[/tex]
[tex]\hat q[/tex] = 1 - 0.14
[tex]\hat q[/tex] = 0.86
The margin of error = 0.03
Given that the confidence interval level = 99%
The significance level is the value of alpha ∝ = 1 - 0.99
∝ = 0.01
There are 12 inches in a foot. There are 36 inches in a yard. If the desk is 4 yards, how many inches long is the desk? *
48 inches long
9 inches long
144 inches long
3 inches long
Answer: It would be 144 inches
Step-by-step explanation:
Answer:
144 inches long
Step-by-step explanation:
there are 36 inches in one yard, so you eliminate any answers that are under 36 inches. Then you multiple 36inches times 4 yards to find your answer. 36 x 4 = I44
A=4ℼR2 solve for R
SHOW ALL STEPSSSSSSSSS
Answer:
[tex]R=\frac{1}{2} \sqrt{\frac{A}{\pi }}[/tex]
Step-by-step explanation:
To solve an equation for one of its value
Underline the variable you need to solve for itSeparate this variable on one side and other terms on the other sideMake its coefficient equal to 1∵ A = 4πR²
→ Underline R
∴ A = 4πR²
→ Move 4π to the other side by dividing both sides by 4π
∵ [tex]\frac{A}{4\pi }=\frac{4\pi R^{2} }{4\pi }[/tex]
∴ [tex]\frac{A}{4\pi }=R^{2}[/tex]
→ To find R take √ for both sides
∴ [tex]\sqrt{\frac{A}{4\pi }}=\sqrt{R^{2} }[/tex]
→ You can simplify [tex]\sqrt{\frac{1}{4}}[/tex] to [tex]\frac{1}{2}[/tex]
∴ [tex]\frac{1}{2} \sqrt{\frac{A}{\pi }}=R[/tex]
→ Switch the two sides
∴ [tex]R=\frac{1}{2} \sqrt{\frac{A}{\pi }}[/tex]

the volume of the box is ___
Answer:
[tex]V=80x-36x^2+4x^3[/tex]
Step-by-step explanation:
The volume of a box of dimensions a, b, c is:
V=abc
The box shown in the image has dimensions 8-2x, 10-2x, x, thus its volume is:
[tex]V=(8-2x)(10-2x)(x)[/tex]
Operating the first two brackets:
[tex]V=(80-16x-20x+4x^2)(x)[/tex]
Joining like terms:
[tex]V=(80-36x+4x^2)(x)[/tex]
Multiplying again:
[tex]V=80x-36x^2+4x^3[/tex]
The volume of the box is
[tex]\boxed{V=80x-36x^2+4x^3}[/tex]
Alan has 6 water bottles in her desk. In how many different ways can he choose 2 water bottles?
Answer:
15 ways
Step-by-step explanation:
The answer would be 6 choose 2, which is:
[tex]\frac{6!}{2!4!} = \frac{6\cdot5\cdot4!}{4!2!}=\frac{6\cdot5}{2}=15[/tex]
Therefore, there are 15 ways to choose 2 of the 6 water bottles Alan has.

ab + cd = e
solve for c
Answer:
c= e/d-ab/d
Step-by-step explanation:
The equation ab + cd = e is solved for the variable 'c' will be c = (e + ab) / d.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The equation is given below.
ab + cd = e
Simplify the equation for c, then we have
ab + cd = e
cd = e + ab
c = (e + ab) / d
The equation ab + cd = e is solved for the variable 'c' will be c = (e + ab) / d.

Tres amigos quieren rentar una cuatrimoto la cual cuesta $400 por una hora cada uno pone las siguientes cantidades Adriana 50 Luis 160 y Ramiro el resto cuánto tiempo debe subirse cada quien de acuerdo a las recupero con operaciones por favor y una explicación
Answer:
Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.
Step-by-step explanation:
Asumamos en primer lugar que los tres amigos rentan la cuatrimoto durante una hora, entonces cada persona utiliza la cuatrimoto en proporción al dinero. A continuación, obtenemos el tiempo estimado por cada usuario a partir de una regla de tres simple:
[tex]\Delta t = \frac{c_{a}}{c_{r}}\cdot (60\,min)[/tex]
Donde:
[tex]\Delta t[/tex] - Tiempo de uso de la cuatrimoto, medido en minutos.
[tex]c_{a}[/tex] - Dinero aportado por el usuario, medido en pesos.
[tex]c_{r}[/tex] - Coste de renta de la cuatrimoto, medido en pesos.
Entonces calculamos el tiempo correspondiente a cada amigo:
Adriana ([tex]c_{a} = \$\,50[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,50}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 7.5\,min[/tex]
Luis ([tex]c_{a} = \$\,160[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,160}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 24\,min[/tex]
Ramiro ([tex]c_{a} = \$\,190[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,190}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 28.5\,min[/tex]
Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.

3. The total cost after tax to repair Deborah's computer is represented by , where h represents the number of hours it takes to repair Deborah's computer. a. What part of the expression represents the amount of tax Deborah has to pay? Explain. (3 pts) b. What would the expression be if the company charged Deborah $45 per hour to repair the computer (plus tax)? (3 pts)
Complete question :
Answer:
Kindly check explanation
Step-by-step explanation:
Given the expression :
Total cost after tax = 0.08(50h) + 50h
a. What part of the expression represents the amount of tax Deborah has to pay? Explain
0.08(50h) represents Tha amount of tax Deborah has to pay. This can be interpreted as :
Recall;
Tax amount = tax rate * cost
Cost of repair = 50h = 50 per hour
Tax rate = 0.08 = 8% of the total cost;
Hence; 0.08(50h) = tax Deborah has to pay.
What would the expression be if the company charged Deborah $45 per hour to repair the computer (plus tax)?
If she was charged $45 per hour plus tax. Expression becomes ;
Total cost after tax = 0.08(45h) + 45h
= 3.6h + 45h
= 48.6h

Step-by-step explanation:
" First four terms " means :
t(1) , t(2) , t(3) , t(4)
[tex]t(1) = a(1) = 5(1) - 1 = 5 - 1 = 4 \\ t(2) = a(2) = 5(2) - 1 = 10 - 1 = 9 \\ t(3) = a(3) = 5(3) - 1 = 15 - 1 = 14 \\ t(4) = a(4) = 5(4) - 1 = 20 - 1 = 19 \\ \\ t(1) = 4 \\ t(2) = 9 \\ t(3) = 14 \\ t(4) = 19[/tex]

Given that:
Cindy, who is self-employed, maintains an office in her home that comprises 16% (260 square feet) of total floor space. Gross income for her business is $44,150, and her residence expenses are as follows: Real property taxes $4,188 Interest on mortgage 6,980 Operating expenses 3,490 Depreciation (based on 16% business use) 3,755 If required, round your final answer to the nearest dollar. a. What is Cindy's office in the home deduction based on the regular method? $ b. What is Cindy's office in the home deduction based on the simplified method? $
Deduction :
Real property taxes = 16% * $4,188 = $670.08
Interest on mortgage = 16% * 6,980 = $1116.80
Operating expenses = 16% * 3,490 = $558.40
Depreciation (based on 16% business use) = 3,755
Total deduction:
$(670. 08 + 1116.80 + 5558.40 + 3755) = $11,100.28
Simplified deduction :
$5 per square foot of home used for business
Number of square feet = 260
$5 * 260 = $1300
