One real, rational, Option A

Answer:

one real solution

Step-by-step explanation:

Use the discriminant to answer the questions. 32x - 4 = 4x^2 + 60

Move all the terms to one side and make right hand side 0

32x - 4 = 4x^2 + 60

subtract 4x^2 from both sides

-4x^2 + 32x -4 = 60

Subtract 60 from both sides

-4x^2 + 32x - 64=0

a= -4, b= 32, c= -64

discriminant is b^2 - 4ac

(32)^2 - 4(-4)(-64)= 1024 -1024=0

Discriminant b^2 - 4ac=0

so the equation has only one real solution

Jonathan borrowed $475 at a simple annual interest rate of 2%. How many years will it take him to repay the loan if he wants to
vovikov84 [41]
Firstly you would times 475 by the percentage, which you can convert to a decimal my multiplying the percentage by 100.

475 * 0.02 = 9.50

Then divide the interest by the amount of interest per year:
38 / 9.5 = 4.

The answer would be 4 years.

Hope this helps.

Which of the following is a true statement for 0 degrees less than theta less than 90 degrees?
Grace [21]

Answer:

c

Step-by-step explanation:

See the graph for an example using the specific angles \theta=60^\circ , \,\, \180^\circ-\theta=120^\circ

See how the red segments are equal  in length but going in opposite directions?

\tan{60^\circ}=\sqrt{3} \\ \tan{120^\circ=-\sqrt{3}

a. This can't be correct: it says \tan{\theta} is equal to its opposite. That is never true in Quadrant I where all tangent values are positive.

b. Not true in Quad. I. Consider \tan{60^\circ}, \,\, \tan{30^\circ}.

What is the 185th digit in the following pattern 12345678910111213141516...?
Natalka [10]
1-9  = 9 digits
10-99 = 180 digits
So if we continue the pattern to 99, there are 189 digits, and the last 5 digits would be 79899.  Counting backwards: 189th = 9, 188th = 9, 187th = 8, 186th = 9, 185th = 7.

The 185th digit is 7.

What is the sum of 2/10 + 6/100
kogti [31]

Answer:

26/100 which is simplified to 13/50

Step-by-step explanation:

you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50
