Hi can someone tell me how is the answer 113?? how do i type it in the calculator?? im confused can someone please explain ASAP THANK YOU

You shouldn't need a calculator for this. The quadratic equation is written in standard form.

ax^2 + bx + c = 0

You substitute a, b, and c into the discriminant formula and solve as shown in the example in the picture you provided.

(-7)^2 - 4(2)(-8)

49 - 4(-16)

49 - (-64)

49 + 64

113

Best of Luck!

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
