Plzzzzz give me Brainliest!!!!!
<u>B) </u>
<u>C) </u> volume = 
.
<u>Step-by-step explanation:</u>
Here we have , The base of an open rectangular box is of length (2x+5) cm and width x cm. The area of this base is 58cm^2. The height of the open box is (x-2) cm. We need to find the following :
a) show that 2x^2+5x-58=0
We know that area of rectangle = 
⇒ 
Putting values according to question we get :
⇒ 
⇒ 
⇒ 
b) solve the equation in the question above, giving your answer to 2 decimal places
Solving this equation :
⇒
By quadratic formula
⇒ 
⇒ 
⇒ 
⇒ 
{ Since side can't be negative ! }
⇒
c) calculate the volume of the box, stating units of you answer
Since x = 4.28 , other sides are
We know that volume is given by :
⇒ 
⇒ 
⇒
Therefore , volume = .
X^12/x^9=125
Simplify the left side
x^3=125
Find the cube root of both sides
x=5
Final answer: The number is 5
Answer:
sqrt(3/8) = t
.61237 = t
Step-by-step explanation:
h(t)=−16t^2+10
Let h(t) = 4
4 =−16t^2+10
Subtract 10 from each side
4-10 =−16t^2+10-10
-6 = -16 t^2
Divide by -16
-6/-16 = t^2
3/8 = t^2
Take the square root of each side
sqrt(3/8) = sqrt(t^2)
sqrt(3/8) = t
.61237 = t
We only take the positive since time is not negative
Answer:
60 degress
Step-by-step explanation:
How I got it:
1. Find out the angel of each side. 360 divded by 6 = 60
2. Get the answer of 60
Advice:
-Make an polygon using paper and rotate it. (Use protractor and ruler if your gonna do it)
