Multiply the amount of book Robin read by 1/2.
3/4 x 1/2 = 3/8
Mark read 3/8 of the book.
We have f(x) = 0;
Then x^2 - 1 - 2x - 2 = 0;
(x - 1)(x + 1) - 2(x + 1) = 0;
(x + 1)(x - 1 - 2) = 0;
(x + 1)(x - 3) = 0;
x + 1 = 0 or x - 3 = 0;
x = -1 or x = 3;
The zeroes of f are -1 and 3.
Answer:
Step-by-step explanation:
You are given adjacent and you want opposite. You can use the relationship of tangent. SOHCAHTOA
tan(51) = x/15
x = 18.5
Answer:
angle B=92
Step-by-step explanation:
cos C= adj/hyp
sin C=12/14=6/7 ( in rad.)
angle C is 31 degree
the sum of angles of triangle =180
angles A+B+C=180
angle B=180-(31+57)=92 degrees
Answer:
- quotient: 2x^2 +3x +7
- remainder: 20
Step-by-step explanation:
See the attachment.
At each step, the value being subtracted from the dividend is the product of the quotient term and the divisor. The quotient term is found by dividing the highest-degree term of the dividend by the highest degree term of the divisor (x).
When the dividend has a degree that is less than the degree of the divisor, we call that value (20) the remainder.
