Quadratic refers to x^2 so the quadratic formula can be used to solve an equation only at the highest degree in the equation is a two/squared
Answer:
Brand C
Step-by-step explanation:
Answer:
Maximum: C= 6(5) + 2y or <u>C= 30 + 2y</u>
Step-by-step explanation:
X can be greater than or equal to 0, but can also be less than or equal to 5.
Y is greater than or equal to 0.
4 times x then subtracted by y is greater than or equal to 1.
Since X can't go higher than 5, the maximum is 5.
Y can be anything since it can be greater than or egual to 0 and either way it would be greater than one.
I hope I could help!
Answer:
Step-by-step explanation:
Each signal unit cubes are 1 cm to each side
the dimensions of the large cube is 4 by 6 by 3 width height and depth
a) volume of the cube Vol = area of the base times height
area of the base = the width times the depth
Volume = Base Depth
= Width x Depth x Height
= 4 x 3 x 6
= 12 x 6
Vol = 72 cm ³
b ) the volume of the smaller cuboid has different dimensions
the smaller cube is 2 by 2 by 1 width height and depth
Volume = Base Depth
= Width x Depth x Heigh
= 2 x 2 x 1
Vol smaller cuboid = 4
How many smaller cubes can be made?
The obvious answer might be to straight up divide the large cube volume by the smaler cuboid volume. That might work IF all of the cuboid dimensions divide evenly into the cube dimensions.
Number of cuboid = Volume of the cube / Volume of the cuboid
= 72 / 4
= 18
Check this answer by dividing the dimension of the cube by the cuboid
4 by 6 by 3
2 by 2 by 1
(4/2) by (6/2) by (3/1)
2 by 3 by 3 = 2 x 3 x 3 = 18
This is a right & isosceles triangle A =90° (Given) & AB = BC (given )
Apply Pythagoras
x² = 5(√2)² + 5(√2)² (since the 2 legs are equal)
x² = 5.2 + 5.2 Since (√2)² =2
x²=10 + 10 & x² = 20 & x=√(20) = 2√5 (the answer given are wrong.2√5 is the right answer)<u />
