Answer:

0.5a+7.5b^2

Step-by-step explanation:

4b^2+3.5a-2a+3.5b^2-a

Group similar terms together:

3.5a-2a-a+4b^2+3.5b^2

Add the term b^2:

3.5a-2a-a+7.5b^2

Subtract the term a:

0.5a+7.5b^2

Which function has a simplified base of 4^3√4?
IrinaVladis [17]

Answer:

The function is f(x) = 4(\sqrt[3]{16} )^{2x}.

Step-by-step explanation:

We have to choose from options the exponential function which has a simplified base of 4∛4 i.e. ∛(256).

Now, the exponential function in the option III will be the answer.

The function is f(x) = 4(\sqrt[3]{16} )^{2x}.

So, the base is (\sqrt[3]{16} )^{2} = \sqrt[3]{16^{2}} = \sqrt[3]{256} = 4\sqrt[3]{4}. (Answer)

The general formula of an exponential function is f(x) = a(b)^{x} , where b is called the base of the function.

In what line do planes A and QRV intersect?
BabaBlast [244]

Answer:

Plane A and QRV intersection line is QR.

Explanation:

The plane QRV contains the rectangle QRVN. This rectangle intersects the plane A in the line QR.

Plane A and QRV intersection line is QR.

If one knows a specific line in one plane (for example, two points in the plane), and this line intersects the other plane, then its point of intersection.

Thus, it is on the line of intersection for the two planes.

We know that
The volume of a circular truncated cone=(1/3)*pi*[r1²+r1*r2+r2²]*h
where
r1=7/2-----> 3.5 in
r2=10/2----> 5 in
h=12 in
volume of a circular truncated cone=(1/3)*pi*[3.5²+3.5*5+5²]*12
volume=688 in³

the answer is
688 in³

David is throwing a stone in the air at an angle from the ground with an initial velocity of 30 feet per second. The equation gi
Shtirlitz [24]

Answer:

42 feet.

Step-by-step explanation:

h=-10t² + 40t +2

The vertex of the quadratic function described by the equation is located at

 t = -(40)/(2(-10)) = 2

Next is to find the value of height at t=2 will be

 h = -10(2²) +40(2) +2 = -40 +80 +2 = 42feet

The maximum height is 42 feet.
