Which graph shows the zeros of the function f(x) = 2x2 + 4x – 6 correctly?​

Answers

Answer 1

Answer:

Divide through by  2  .

x2 - 2x - 3  =  0           What two numbers add to  -2  and multiply to  -3  ? →   +1   and   -3

                                  So...we can factor it like this...

(x + 1)(x - 3)  =  0        Set each factor equal to zero and solve for x.

x + 1  =  0          and          x - 3  =  0

x  =  -1               and          x  =  3

It costs $5.44 for a pack of 16 pens. Find the unit price in dollars per pen. Round your answer to the nearest cent​

Answers

$3.68 for 16 pens

$3.68 per 16 pens

($3.68) / (16 pens)  

$0.23 / (1 pen)

$0.23 / pen

$0.23 per pen

I am not 100% sure sorry

Regular - $0.34

Rounded- $0.30

Explanation:

to find unit rate, set up the problem like a fraction. put the total cost on top, and the number of pens in a pack on bottom. Divided by the number of pens in the pack, which is 16. The answer will be the unit rate.

FOR EXAMPLE:

5.44/16 DIVIDED BY 16.

on the bottom you would get one because 16 divided by 16 is one. And on the top it would be 5.44 divided by 16 which is $0.34.

A jar contains n nickels and d dimes. There is a total of 206 coins in the jar. The value of the coins is $13.95. How many nickels and how many dimes are in the jar? ​

Answers

Answer:

73 dimes and 133 nickels

Step-by-step explanation:

$13.95 = 1395 cents

5n + 10d = 1395     (since each nickel is 5 cents and each dime is 10 cents)

5n = 1395 - 10d      (subtract 10d from both sides to solve for n)

n = 279 - 2d

n + d = 206

279 - 2d + d = 206   (substitute n with the previous expression)

279 - d = 206         (add variable d and -2d)

-d = -73        (solve for d and divide both sides by negative 1)

d = 73          

n + 73 = 206 (solve for n and subtract both sides by 73)  

n = 133

Last year, a computer store sold 200 laptops at the price of $1,000 per laptop. The store manager is planning for the upcoming year. She creates the graph
shown below of the projected revenue from the sales of laptop computers for next year depending on the price increase per laptop.

Answers

Answer:

The maximum revenue of $225,000 occurs when the laptops are priced at $1,250.

Step-by-step explanation:

The vertex of the parabola shows that; maximum revenue of $225,000 occurs when the laptops are priced at $1,250.

What does the vertex of the parabola represent?

We are given a graph titled projected laptop revenue based on price with price increase per laptop on the x-axis and total revenue from laptop sales on the y-axis.

Now, the vertex of the parabola is the peak of the parabola and from the coordinates on the graph, we can conclude that maximum revenue of $225,000 occurs when the laptops are priced at $1,250.

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 11)(0,11) and (3, 3773)(3,3773).

Answers

Answer:

y = 11(7)^x

Step-by-step explanation:

The exponent equation that goes through points (0, 11) and (3, 3773) will be y = 11 · (7)ˣ.

What is an exponent?

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

y = a(b)ˣ

The equation passes through (0, 11) and (3, 3773). Then the equation will be given as,

ab⁰ = 11

a = 11

Then the other equation is given as,

ab³ = 3773

11 b³ = 3773

b³ = 343

b³ = 7³

b = 7

Then the exponent equation that goes through points (0, 11) and (3, 3773) will be y = 11 · (7)ˣ.

Alice purchased a compass from an online retailer. The cost of the compass was $60.00, and was marked 40% off. Sales tax for the item is 7.5%, plus a shipping fee of $5.99. What is the final price, including discount, tax and shipping?​

Answers

Answer:

$60.00 * 1.075 * .6 + 5.99 = $44.69

when you have multiple fees and discounts and taxes and whatever else, you should follow the order of all operations.  multiplication and division before addition and subtraction, and so on.  

Step-by-step explanation:

For discount and sales tax you multiply, and for shipping you just add the fee.  We will save shipping for last since it doesn't effect the discount or tax.  Meanwhile you could apply the discount and tax in any order.

To apply a discount you take the price and multiply by 1 minus the percent in decimal form.  decimal form of a percent is basically the number divided by 100.  so 40% = .4 then 1 - .4 = .6

to apply a ttax you multiply 1 plus the percent in decimal form.  tax is 7.5% so in decimal form that's .075 then 1 plus the tax is 1.075

so now you multiply 60 * .6 * 1.075 and also remember 60 * .6 * 1.075 = 60 *  1.075 * .6 but the answer is $38.70

Now add the shipping, so 38.70 + 5..99 = $44.69

Which is more, 5 tons or 9,998 pounds?

Answers

Answer:

5 tons

Step-by-step explanation:

5 tons are more than 9,998 pounds.

What is ratio?

Ratio essentially compares quantities, i.e., it displays the value of one quantity in relation to the other quantity.

The ratio of two values, a and b, will be a:b.

According to question,

We have to find which value is greater, 5 tons or 9,998.

Since,

1 ton = 2000 pounds

Therefore,

5 tons = 5 x 2000 pounds

5 tons = 10,000 pounds.

It implies that, 5 tons are more than 9,998 pounds.
