Mathematics
1 answer:
o-na [289]4 years ago
3 0

Answer:

B. 2, -0.5

Step-by-step explanation:

Given the equation

-2x^2+2=-3x

Rewrite it as

-2x^2+3x+2=0

Graph the graph of the quadratic function y=-2x^2+3x+2

The grapg of this function is a parabola going downwards.

This parabola intersects the x-axis at points x = -0.5 and x = 2, so the solutions of the equation are x = -0.5 and x = 2

What are rational numbers? Why is it important to study rational numbers?
xxTIMURxx [149]

Answer:

Any number that can be written as a fraction with integers is called a rational number . For example, 17 and −34 are rational numbers. (Note that there is more than one way to write the same rational number as a ratio of integers. For example, 17 and 214 represent the same rational number.)

how does knowing where the halfway point is help you find which hundred thousand 138,202 is closest to? Explain
ExtremeBDS [4]
Knowing the halfway point (which is 5) helps you so you know wither or not the hundred thousands place goes high or stays the same.
So, for this problem 138,202 would round out to 100,000 because the 3 is below 5 so the hundred thousands place stays the same.

PLEASE HELP kelly invested $1875 in a savings account which earns 3.35% interest compounded quarterly what will the account be w
attashe74 [19]
The account will be worth $2368.20 in 7 years.

The compound interest formula is

A=p(1+\frac{r}{n})^{n\times t}

where p is the principal invested, r is the interest rate as a decimal number, n is the number of times the interest is compounded yearly, and t is the amount of time.

3.35% = 3.35/100 = 0.0335.

Using our information, we have:
A=1875(1+\frac{0.0335}{4})^{4*7}

which comes out to $2368.20.

Square root of 22801 by long division method
mezya [45]
First step: partition the number you want to square root into a block of 2 digits, starting from the last digit (first diagram)

Second step: As our number is a five-digits, we ends up with 2  28  01. Pick a number that could be squared to get the first partition, 2. This number is 1, since 1×1=1

Third step: Write 1 on the top and on the side, as shown in the second graph

Fourth step: Double the number on the side, which is 1+1=2 and use this number as the first digit for the next multiplier. Meanwhile, subtract 1 from 2 inside the root sign to get 1, then pull the other two digits, 28

Fifth step: We need a value in the boxes that when we multiply together will give a number less than 128. We choose 5 as 25×5=125

Sixth step: Subtract 125 from  128 to give 3, and as the same concept with long division, bring down the 0 and the 1. So we have 301

Seventh step: Add 5 to the multiplier on the left, so 20+5=30, which we will use on the side as the hundred and ten digits.

Final step: Find a number to fit in the boxes. We choose 1 since 301×1=301

And hence the square root of 228801 is 151
