Find the coordinates of the three points on the graph of y = (1/2)x² -2x whose x-values are −2, 0, and 4.

MaRussiya [10]

Answer:

y = 6

y = 0

Step-by-step explanation:

$y=\frac{1}{2}x² -2x$

When, x = -2

$y=\frac{1}{2}\times (-2)^2-2\times(-2)\\\Rightarrow y=\frac{1}{2}4+4\\\Rightarrow y=2+4\\\Rightarrow y=6$

y = 6

When, x = 0

$y=\frac{1}{2}\times (0)^2-2\times(0)\\\Rightarrow y=0+0\\\Rightarrow y=0$

y = 0

When, x = 4

$y=\frac{1}{2}\times (4)^2-2\times(4)\\\Rightarrow y=\frac{1}{2}16-8\\\Rightarrow y=8-8\\\Rightarrow y=0$

y = 0

Consumer math help

denis23 [38]

<span>1. When you are paying a bill in full, said bill is completely paid off. In other words, the bill amount has been fulfilled by the consumer in a sort of payment. The answer is a. consumer is paying it off. 2. APR is a rate that is used frequently when applying and using a credit card. It stands for c. annual percentage rate or the percentage that will be charged when a credit card is not paid in full by the due date each month. 3. When calculating interest accrued you should multiply the principal by the APR & number of months, then divide the number of months in a year (12). This will be the interest that the consumer has gained and must pay off to the lender.</span>

The Richter Scale gives a mathematical model for the magnitude of an earthquake in terms of the ratio of the amplitude of an ear

Alexeev081 [22]

Answer:

The magnitude of the claimed earthquake would be 13.67.

Step-by-step explanation:

The 1906 earthquake had a intensity of A and a magnitude of 7.8.

S is going to have the same value, so i am going to write as 1. So:

$\log{A} = 7.8$
