Answer: t= 13.4
Step-by-step explanation:
The given equation is 
To solve this equation for 't', we first divide both sides by
, we get

Taking log on both the sides, we get

Since 
Then,

Hence, the value of t is 13.4.
6. instead of multiplying by 4/3 it would be 2/3 because it is half a sphere.
9. you should have multiplied by pi first then multiply by 4/3 to make it more easy for you
Answer:
the answer is 15x^8 y^3
Step-by-step explanation:
the area of a rectangle is length times width right? this means you have to multiply the values that represent the length and width. in this case those values would be 5x^6 y^2 and 3x^2 y
step 1. set up your problem
it should look like this:
(5x^6 y^2)(3x^2 y)
step 2. multiply the values with corresponding variables
first, x values
(5x^6)(3x^2)
5×3=15 and x^6 × x^2=x^8 when multiplying exponents you add the powers the numbers are raised to. in this case 6+2=8
you should end up with 15x^8
next, y values
y^2 + y
remember what i said about multiplying exponents? you just add the power the variables are raised to. in this case, 2 and 1. when their is no exponent we just add a 1. so, 2+1=3
you end up with y^3
lastly, combine
15x^8 + y^3 = 15x^8y^3
Answer:
The vertex of this parabola is 
Step-by-step explanation:
One way of finding the x-coordinate of the vertex of a parabola is by using the equation 
From the function
, we can see that

This means that

So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.

Thus, the vertex of this parabola is 
Lol, you said 20 points but that’s only 12 but sorry I’m also failing in math☹️☹️☹️ so i don’t really know the answer
