Is (0,0) a solution to this system?

Mathematics
1 answer:
V125BC [204]3 years ago
5 0

Answer:

A. Yes, (0,0) satisfies both inequalities.

Step-by-step explanation:

The given inequalities are;

y\ge x^2+x-4

and

y\:

For (0,0) to be a solution to the given system of inequalities then it must satisfy both inequalities.

We substitute (0,0) into the system of inequalities to obtain;

0\ge 0^2+0-4 This implies that; 0\ge-4; True

and

0\:  This implies that; 0\:: True

Since (0,0) satisfies the two systems, it is a solution.

The correct choice is A.

Aubrey invested $61,000 in an account paying an interest rate of 1.9% compounded continuously. Assuming no deposits or withdrawa
Hitman42 [59]

Answer: 9.9 years.

Step-by-step explanation:

If interest is compounded continuously, then formula to compute final amount A = Pe^{rt}, where P =initial amount, r= rate of interest , t=time.

Given: P= $61,000, r= 1.9% =0.019  , A = $ 73600

Substitute all values in formula

73600=61000e^{0.019t}\\\\\Rightarrow\ \dfrac{73600}{61000}=e^{0.019t}\\\\\Rightarrow\ 1.20655738=e^{0.019t}

Taking natural log on both sides

\ln (1.20655738)=0.019t\\\\\\ 0.18777116=0.019t\\\\\\ t=\dfrac{0.18777116}{0.019}\\\\\\ t=9.88269263\approx9.9\ \text{years}

Hence, the required time = 9.9 years.

Svetlanka [38]

Answer:

Sandwich sells for  $4.76  .

Step-by-step explanation:

As given

It costs $2.80 to make a sandwich at the local deli shop.

To make a profit, the deli sells it at a price that is 170% of the cost.

170% is written in the decimal form

= \frac{170}{100}

= 1.7

Thus

Sandwich selling cost = 1.7 × Cost of making

Put all the values in the above

Sandwich selling cost = 1.7 × $ 2.80

                                    = $4.76

Therefore the Sandwich sells for  $4.76  .

Susan is celebrating her birthday by going out to eat at five guy's for burgers. If the bill in $40 and she wants to leave a tip
damaskus [11]

Answer:

  $6

Step-by-step explanation:

Susan can easily figure the tip by the following procedure. 10% of the bill is the amount with the decimal point moved one place to the left, so is $4.00. 5% of the bill is half that, or $2.00.

15% of the bill is 10% + 5%, so is $4.00 +2.00 = $6.00. The tip will be $6.00.
