Respond to the following question with either a TRUE or FALSE: "The following parabola opens down: f (x) = -x2 + 5"
O TRUE because the leading coefficient is negative.
O TRUE because the linear function is negative.
O FALSE because the 5 is.positive.
O FALSE because this function is actually linear and not a parabola.
O I'm not sure how to approach this problem...yet.

Answers

Answer: A) True because the leading coefficient is negative

Explanation:

The leading term is -x^2 since this term has the largest exponent.

The leading coefficient is -1 as it's the coefficient of the leading term.

It might help to write -x^2 as -1x^2

The negative leading coefficient makes the parabola open downward, so each endpoint goes off to negative infinity. The graph looks like a frowny face. You can think of a negative emotion going with a frowny face, so that negative emotion matches with the negative leading coefficient. There are probably other ways to remember but that's the trick I use.

Strip malls appear to popping up everywhere. The relationship between the actual price of a strip mall and the listing price is modeled in the least-squares regression line Ĉ = 0.2 + 1.011. Both amounts are in hundred-thousands of dollars. Let L represent the listing price and C represent the sales price. Which of the following is the best interpretation of the slope of the regression line?
A)For each hundred-thousand-dollar increase in the listing price, the sales price will increase by $1.01.
B)For each hundred-thousand-dollar increase in the listing price, the sales price will increase by $101,000,
C)For each hundred-thousand-dollar increase in the listing price, the sales price will decrease by $101,000.
D)For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $1.01.
E)For each hundred-thousand dollar increase in the listing price, the sales price is predicted to increase by $101,000.​

Answers

Answer:

The correct option is;

E) For each hundred-thousand dollar increase in the listing price, the sales price is predicted to increase by $101,000

Step-by-step explanation:

Whereby the relationship between the actual price of a strip mall and the listing price is modeled according to the least squares regression line as follows;

C = 0.2 + 1.01·L

Where;

L = The listing price

C = The sales price

Where both amounts are in hundred-thousands of dollars;

Therefore, given that the slope is 1.01, we have that for an increase of $100,000 for the listing price, L, which is 1 unit increase the sale price increases as follows

C₁ = 0.2 + 1.01 × 1 = 1.21

While for an increase of an extra $100,000, to make the listing price. $200,000 or 2 units, we have;

C₂ = 0.2 + 1.01 × 2 = 2.22

The increase is C₂ - C₁ = 2.22 - 1.21 = 1.01

C₂ - C₁ = $100,000 × 1.01 = $101,000

The increase is C = $101,000

Whereby, the equation is a linear regression line which is a model for prediction, we have;

The predicted increase in the sale price is $101,000 for each $100,000 increase in the listing price.

Answers

Answer:

Find out yourself buddy XD

Answer:

his average speed was 60 miles per hour

Step-by-step explanation:

their are three ways to get the answer

1. if you take the 0 away from 240 it becomes 24, and 24 divided by 3 = 6 add the the 0 back in and you get 60.

2. 240 divided by 3 = 60

You go shopping at a local department store with your friend and cousin. You buy one pair of jeans, four pairs of shorts, and two shirts for $84. Your friend buys two pairs of jeans, one pair of shorts, and three shirts for $76. Your cousin buys one pair of jeans, two pairs of shorts, and one shirt for $52. How much does each item cost?

Answers

Answer: Cost per pair of jeans = $ 20

Cost per pair of shorts = $12

Cost per shirt = $8

Step-by-step explanation:

Let x= cost per pair of jeans

y = Cost per pair of shorts

z= cost per shirt.

For you, total cost = x+4y+2z= 84

For your friend,  total cost = 2x+y+3z=76

For cousin, total cost = x+2y+z= 52

Required system:

[tex]x+4y+2z=84\ (i)\\ 2x+y+3z=76\ (ii)\\ x+2y+z=52\ (iii)[/tex]

from (i), [tex]x=84-4y-2z[/tex]    (*)

put this in (ii) and (iii) we get

[tex]2\left(84-4y-2z\right)+y+3z=76\\\Rightarrow\ -7y-z+168=76\ (iv)\\\\ 84-4y-2z+2y+z=52\\\Rightarrow\ -2y-z+84=52 \ (v)[/tex]

from (iv), [tex]y=-\frac{z-92}{7}\ (vi)[/tex]

[tex]\mathrm{Subsititute\:}y=-\frac{z-92}{7}\ \text{in}\ (v)[/tex]

[tex]-2\left(-\frac{z-92}{7}\right)-z+84=52\\\\\Rightarrow\ -2\left(-\frac{z-92}{7}\right)-z=-32\\\\\Rightarrow\ -\frac{5z}{7}-\frac{184}{7}=-32\\\\\Rightarrow\ -5z-184=-224\\\\\Rightarrow\ -5z=-40\\\\\Rightarrow\ z=8[/tex]

[tex]\mathrm{Subsititute\:}z=8\text{ in (vi)}[/tex]

[tex]y=-\frac{8-92}{7}\\\\\Rightarrow \ y=12[/tex]

[tex]\mathrm{Subsititute\:}z=8,\:y=12\text{ in (*)}[/tex]

[tex]x=84-4\cdot \:12-2\cdot \:8\\\\\Rightarrow\ x= 20[/tex]

Hence, x= 20, y= 12 , z=8

So, Cost per pair of jeans = $ 20

Cost per pair of shorts = $12

Cost per shirt = $8

Don Luis, el carpintero, desea construir un mueble para estantería, el cual es in- dispensable que tenga dos áreas cuadradas, donde el cuadrado mayor mida por lado, una unidad menor que el doble del largo del cuadrado menor. El área total del mueble será de 121 pies cuadrados.

Answers

Answer:

El área de un cuadrado de lado L es:

A = L*L

Y sabemos que si el cuadrado menor tiene lado de largo L, entonces el cuadrado mayor tiene lado de largo 2*L - 1ft

Área menor = L*L = L^2

Área mayor = (2L - 1ft)*(2L - 1ft)

El área total es igual a la suma de ambas áreas:

121 ft^2 = L^2 + (2L - 1ft)*(2L - 1ft) = L^2 + 4*L^2 - 2ft*L + 1ft^2

Ahora podemos resolver esto para L.

121 ft^2 = 5*L^2 - 2ft*L + 1ft^2

0 = 5*L^2 - 2ft*L - 120 ft^2.

Usando la formula de Bhaskara, las soluciones son:

[tex]L = \frac{2ft +- \sqrt{(2ft)^2 - 4*5*(-120ft^2)} }{2*5} = \frac{2ft +- 49ft}{10}[/tex]

Las dos soluciones son:

L = (2ft + 49ft)/10 = 51ft/10 = 5.1ft

L = (2ft - 49ft)/10 = -4.7 ft

Como estamos hablando de el largo de algo, la única opción que tiene sentido es la positiva.

Entonces el largo de los lados del cuadrado menor es L = 5.1 ft

El largo de los lados del cuadrado mayor es M = 2*5.1ft - 1ft = 9.2ft

Can someone help me pls. the Subterranean roller coaster rises up to 50.6 feet above the ground before dropping 100.7 feet into an underground cavern. Describe the height of the roller coaster at the bottom of the cavern.

Answers

Answer:

-50.1

Step-by-step explanation:

The height of the roller coaster at the bottom of the cavern is 50.1 feet down from the ground level.

What is Subtraction?

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference.

Given that,

Subterranean roller coaster rises up to 50.6 feet above the ground before dropping 100.7 feet into an underground cavern.

So the height of the roller coaster when it rises is 50.6 feet from the ground .

After that it drops to 100.7 feet into an underground cavern.

Height of the roller coaster now = 50.6 - 100.7

                                                      = -50.1 feet

Negative sign indicates that it is below the ground level.

Hence the height of the roller coaster at the bottom of the cavern is -50.1 feet.
