Answer = 14/8
Step by step explanation
2 x 7/8
= (2x7)/8
= 14/8
Answer:
the temperature is -5C which is negative so its behind the zero on a number line and 6C is positive which is infront of the zero so it would be 1C by noon
Step-by-step explanation:
Answer:
(i) (f - g)(x) = x² + 2·x + 1
(ii) (f + g)(x) = x² + 4·x + 3
(iii) (f·g)(x) = x³ + 4·x² + 5·x + 2
Step-by-step explanation:
The given functions are;
f(x) = x² + 3·x + 2
g(x) = x + 1
(i) (f - g)(x) = f(x) - g(x)
∴ (f - g)(x) = x² + 3·x + 2 - (x + 1) = x² + 3·x + 2 - x - 1 = x² + 2·x + 1
(f - g)(x) = x² + 2·x + 1
(ii) (f + g)(x) = f(x) + g(x)
∴ (f + g)(x) = x² + 3·x + 2 + (x + 1) = x² + 3·x + 2 + x + 1 = x² + 4·x + 3
(f + g)(x) = x² + 4·x + 3
(iii) (f·g)(x) = f(x) × g(x)
∴ (f·g)(x) = (x² + 3·x + 2) × (x + 1) = x³ + 3·x² + 2·x + x² + 3·x + 2 = x³ + 4·x² + 5·x + 2
(f·g)(x) = x³ + 4·x² + 5·x + 2
STEP 1
find cubic feet; multiply the three dimensions together; be sure to use the same unit of measure for all three dimensions: 6 inches is equal to 1/2'.
= 38' * 37' * 1/2'
multiply
= 703 cubic feet
STEP 2
divide cubic feet in step 1 by number of cubic feet in a cubic yard
27 cubic feet= 1 cubic yard
= 703 ÷ 27
= 26.037 cubic yards
STEP 3
multiply cubic yards in step 2 by cost per cubic yard
= 26.037 * $150
= $3,905.555
= $3,906 rounded to nearest dollar
ANSWER: It will cost $3,906 (rounded to nearest dollar).
