Ryker is given the graph of the function y= 1/2x^2 - 4 . He wants to find the zeros of the function but is unable to read them exactly from the graph. Find the zeros give answer to nearest tenth

Answers

Answer 1

Answer:

Answer:

x= 2.8 and x= -2.8

Step-by-step explanation:

$y=(1)/(2)x^2-4$

To find out the zeros, we replace x y with 0 and solve for x

$0=(1)/(2)x^2-4$

Add 4 on both sides

$4=(1)/(2)x^2$

Multiply by 2 on both sides

8= x^2

Now we take square root on both sides

x= +- $√(8)$

x=2.82843 and x=-2.82843

x= 2.8 and x= -2.8

Answer 2

Answer: $y=(1)/(2)x^2-4\n\nzeros\ when\ y=0\n\n(1)/(2)x^2-4=0\n\n(1)/(2)x^2=4\ \ \ \ /\cdot2\n\nx^2=8\n\nx=-\sqrt8\ and\ x=\sqrt8\n\n\underline{\underline{x\approx-2.8\ and\ x\approx2.8}}$

D. 1,563,000.

Answers

Round up the millions place digit from 1 to 2 and set the rest of the digits to zeros, resulting in option A. 2,000,000.

To round the number 1,563,385 to the nearest million,

Need to consider the digits in the millions place and the digits immediately to its right (the hundred thousands place).

The millions place digit is 1, and the digit in the hundred thousands place is 5.

Since the digit in the hundred thousands place is 5 or greater,

Need to round up the millions place digit by 1.

Now let's adjust the number accordingly:

Original number: 1,563,385

Rounded to the nearest million: 2,000,000

Therefore, the correct answer to represent the number in nearest million is option A. 2,000,000.

For place values that occur to the left of the decimal point, each place value is ten times ______ than the place value to its right.a. exponential
b. fractional
c. smaller
d. larger

Answers

d. think about it this way. the closer it is to decimal, the closer it is to a whole number which is the "biggest"

Final answer:

Each place value to the left of the decimal point in a number is ten times larger than the place value to its right.

Explanation:

In mathematics, specifically in the idea of place value, each position to the left of the decimal point is ten times larger than the place value to its right. For example, in the number 1234.0, the '1' is in the thousands place, which is ten times larger than the hundreds place where '2' is located. Likewise, the '2' in the hundreds place represents a value that is ten times larger than the tens place where '3' resides, and so on.
