Answer:
The answer is C
Step-by-step explanation:
Move the nine to the other side of the equal sign
Use the quadratic formula
Find a, b, and c
A=2, B=1, C=-10
Plug them in
1 squared minus 4(2)(-10)
1+80
81
Square root of 81=9

Answer:
76 m²
Step-by-step explanation:
The figure has been decomposed into 3 rectangles as shown in the attachment. Therefore:
Area of the figure = area of rectangle 1 + area of rectangle 2 + area of rectangle 3
✔️Area of rectangle 1:
Area = L*W
L = 2 m
W = 4 m
Area = 2*4 = 8 m²
✔️Area of rectangle 2:
Area = L*W
L = 4 m
W = 6 - 4 = 2 m
Area = 4*2 = 8 m²
✔️Area of rectangle 3:
Area = L*W
L = 10 m
W = 6 m
Area = 10*6 = 60 m²
✅Area of the figure = 8 + 8 + 60
= 76 m²
Answer:1526.81 cm cubed
Step-by-step explanation:
v=(pi)radius^2(height)
v=3.14150(9)^2(6)
v=1526.81 cm cubed
incase you we're thrown off by the volume in cubic centimeteres every answer will first come into cubic centimeters not into a measurement.
the basic formula for a cylinder is pi multiplied by the radius squared multiplied by the height follow BEDMAS and you have to square the radius first and then multiply by the height and pi.
a good calculator that ive used for over 6 years is TI-36X PRO and it will be helpful for grade 11 functions
