Answer: The answer is v=25.1 cm³

Step-by-step explanation:

b=4      

h= 2

r= 4/2     r =2 radius is half of the diameter

V=πr²h

v= π(2)²2

v= 25.132741228718

v=25.1 cm³

Solve h=-16t^2+20t+6?​
nikdorinn [45]

i think this is the answer Simplifying h(t) = -16t2 + 20t + 6 Multiply h * t ht = -16t2 + 20t + 6 Reorder the terms: ht = 6 + 20t + -16t2 Solving ht = 6 + 20t + -16t2 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Divide each side by 't'. h = 6t-1 + 20 + -16t Simplifying h = 6t-1 + 20 + -16t Reorder the terms: h = 20 + 6t-1 + -16t

Given the system of linear equations.
Degger [83]

Part(A):

To solve the system of Linear equations using Substitution:

x+y=7 \\ 2x+y=5

Consider the first equation, x+y=7 implies x=7-y

\mathrm{Subsititute\:}x=7-y

2\left(7-y\right)+y=5

14-2y+y=5

14-y=5

\mathrm{Subtract\:}14\mathrm{\:from\:both\:sides}

14-y-14=5-14

-y=-9

\mathrm{Divide\:both\:sides\:by\:}-1

y=9

\mathrm{For\:}x=7-y

\mathrm{Subsititute\:}y=9

x=7-9=-2.\mathrm{The\:solutions\:to\:the\:system\:of\:equationts\:are:}

y=9,\:x=-2

PArt(B): Use a graph to verify your answer to the system:

Using Desmos graphing calculator, graph the two equations.

S_A_V [24]
Y=2000*e^{k*t}

2200=2000*e^{k*4}

e^{k}= ( \frac{22}{20} )^{(1/4)}<span>

so,
 y at t=8 is  2000*(</span><span>( \frac{22}{20} )^{(1/4)})^8
 y = 2000(22/20)^2=2000*1.21=</span><span>2420 thats the answer i hope.</span>

Evaluate
sineoko [7]

We conclude that the equation evaluated in t = 6 and u = 14 is equal to 412.

<h3>How to evaluate an expression?</h3>

Here we have an expression with two variables, t and u.

6t - 32u

And we want to evaluate it in t = 6 and u = 14.

This means that we need to replace the two variables in the equation by the given numbers, so we replace the "t" with a 6, and the "u" with a 14, doing that we get:

6*6 - 32*14

Now we can solve that:

6*6 - 32*14

36 - 448 =  412

We conclude that the equation evaluated in t = 6 and u = 14 is equal to 412.
