Answer:
189
Step-by-step explanation:
step 1: calculate area of rectangle
Area = l × b
= 10× 15
= 150
step 2: calculate area of half a circle
Area = 1/2 (π.r²)
= 1/2 (22/7 × 5²)
=157/4
step 3: Add the area of rectangle and half a circle together
Area = 157/4 + 150
= 189.26
rounded off to the nearest whole = 189
Answer:
Y=60x^(2)-32x+4
Step-by-step explanation:
Y=4(3x-1)(5x-1)
=(12x-4)(5x-1)
=60x^(2)-12x-20x+4
<u>Y=60x^(2)-32x+4</u>

Answer:
-1
Step-by-step explanation:
using PEDMAS(parentheses, exponents, division, multiply, addition, subtraction) to solve the problem
First, multiply (-5)(2) and 2(-3)
(-5)(2) – 2(-3) + 3
=-10-(-6)+3
=-10+6+3
add -10+6
-4+3
Add -4+3
-4+3
=-1
Therefore, (-5)(2) – 2(-3) + 3 is equal to -1
Answer:
c. Multiple zero is 3; multiplicity is 2
Step-by-step explanation:
The factor is repeated, that is, the factor (
x − 3
) appears twice. The number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity. The zero associated with this factor, x = 3
, has multiplicity 2 because the factor (
x − 3
) occurs twice.
Then
Multiple zero is 3; multiplicity is 2.
