Since there are 7 days in a week, we'll multiply 3 by 7, resulting in an answer of: 21.
The solid figure is a rectangular prism.
Step-by-step explanation:
- A rectangular prism is a solid figure that has 12 faces. Each face is in the shape of a rectangle. It is also called a cuboid.
- Along a length of a side, it has the same cross-section. This is what makes it a prism.
- All its edges also meet at right angles or 90°.
- Volume of a rectangular prism = length × width × height
Answer : curve r(t) = t i + (2t - t 2)k intersect the paraboloid z = x 2 + y 2
By the equation of r(t), x = t, y = 0, and z = 
.
Thus, z = 
on solving we get,
= 
Now, we can solve for t
= 0
So, 
= 0
2t ( t - 5/2) = 0
t = 0 , t = 5
plugging these values in t = 0 into r(t)
r(0) = <0 , 0 , 0>
r(5) = < 5, 0 , 25 >
OK is congruent to MK because MO is a full diagonal that is bisected.
Hope this helps :)
Answer:
Multiproperty
Step-by-step explanation:
To solve this problem, we use different properties to arrive at our answer.
Given expression;
4(x + 3) = 20;
First we use the distributive property to expand;
4x + 12 = 20
Now use subtraction property by adding (-12) to both sides;
4x + 12 + (-12) = 20 + (-12)
4x = 8
you can now divide by 4,
x = 2
