-16t^2+20t+65 Quadratic Formula

Shalnov [3]

The value of T is

$\frac{-5+\sqrt{285} }{8}$ OR $\frac{-5-\sqrt{285} }{8}$

Step-by-step explanation:

Assumption: find the values of t

1. Equation is $-16t^{2}$ +20t+65

2. Identify values of a, b and c

a = -16
b = 20
c = 65

3. Write the quadratic formula

t = $\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

4. Substitute the values of a, b and c in the formula

t = $\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

t = $\frac{-20±\sqrt{20^{2}-4(-16)(65) } }{2(-16}$

5. Solve to find the possible values of t

t = $\frac{-20±\sqrt{20^{2}-4(-16)(65) } }{2(-16}$

$\frac{-5+\sqrt{285} }{8}$ OR

$\frac{-5-\sqrt{285} }{8}$

Find the volume of this object.

natka813 [3]

Well to start off, the cone. It says switch ‘’ to 3 and for r (radius), we know the diameter is 6, and the radius is half of it. So the radius is 3 in.
so far it’s 3•3..to the power of two times ‘H’ (height) the height is 10, as you can see in the picture. So the equation we have so far is:
3•3^2•10 / 3 the answer to that is 90in
For the rectangle, the volume for rectangular prisms is length • width • height
so it’s 8 • 8• 1 which equals, 64 inches.
Now all you got to do is Add both answers.
90+64 = 154 in. That’s the answer

The lengths of a diagonals of a rhombus are 10cm and 24cm, what is the perimeter of the rhombus

Fiesta28 [93]

4 * side^2 = diagonal1 ^2 + diagonal2 ^2
4 * side^2 = 24^2 + 10^2
4 * side^2 = 576 + 100
4 * side^2 = 676
side^2 = 169
side = 13
So, the perimeter of this rhombus = 4 * 13 = 52 cm

White raven [17]

Well 62% in decimal format is 0.62 but if you want to find the temperature at night you can multiply 130 by 0.38 which is 38%
