r² = 3.14 x 4² = 50.24 ft²
The angle measurements of a triangle add up to be 180
Q+R+S=180
Q+(60)+(20)=180
Q+80=180
Q=100
your answer is B. 100
Answer:
x = -2,0,2
Step-by-step explanation:
9x^3 - 36x = 0
Factor out 9x
9x(x^2 -4) =0
Factor inside the parentheses, which is the difference of squares
(a^2 -b^2 = (a-b)(a+b)
9x (x-2)(x+2) = 0
Using the zero product property
9x =0 x-2=0 x+2 =0
x=0 x=2 x=-2
x = -2,0,2
Answer:
D. No. She multiplied with the reciprocal of the dividend instead of the reciprocal of the divisor.
Step-by-step explanation:
A. Yes. She solved the problem correctly.
B. No. She multiplied the dividend by the divisor instead of finding the reciprocal.
C. No. She multiplied the denominators instead of finding a common denominator.
D. No. She multiplied with the reciprocal of the dividend instead of the reciprocal of the divisor.
Her workings
7 ÷ 2/ 5
=1/ 7 × 2/ 5
= 2/35
Dividend=7
Divisor=2/5
The correct working
7 ÷ 2/ 5
=7 × 5/2
=35/2
Answer:
(a). Function 1
(b) Function 2
(c) Function 1,2 and 4
Step-by-step explanation:
Find the equation for all functions;
function 1: y= 2x+1
function 2: y= -2x+3
function 3: y= 5x-2
function 4: y= -4x-4
for answer of (a) y= mx+c
c is intercept. so function 1 has closest intercept to 0
for (b) the greatest y intercept is function 2
for(c) slope is m: we have function 1, 2 and 4
