Answer:
x = 6
See image.
Step-by-step explanation:
Logarithms are just another way to write exponents. The base on the logarithm that is the small font subscript IS the base (normal font/on the line) of an exponential equation. The "answer" in the logarithmic equation is the exponent (small font/superscript) .It is just a triple shuffle. When the logarithmic equation cant be worked on to solve it, CHANGE IT to exponential form. See image.
Answer:
C. 20
Step-by-step explanation:
You need you use the Pythagorean Theorem to answer this. We are given the lengths of both legs of the right triangle.
a^2 +b^2 = c^2
If we plug the number given to us into the formula, we get
(12)^2 + (16)^2 = c^2
144 + 256 = c^2
400 = c^2
= C
20 = C
Answer:
a) 2x^4 + 8x^3 + x^2 + 3x
b) evaluate this polynomial at x = 10
Step-by-step explanation:
Hi!
a)
The product of a sum is the sum of the products, having said this:

b)
We can use the result from part a and consider x = 10.
First lets take the first polynomial

Knowing that every number (excepting probably 0, which could be undefined for some or 1 for others) to the power of 0 is one:

Which is the initial number
Now lets conisder the product of the polynomial times x and evaluate it at x=10:



We can now see that teh rule is treu because we can see the whole number as a sum of numbers from 0 to 9 multiplied by a power of 10, and when it is multiplied by 10, each power increases by one, and at the end, the final result is adding a zero at the end
Remember you can do anything to an equation as long as you do it to both sides
x/5-12=48
add 12 to both sides
x/5+12-12=48+12
x/5+0=60
x/5=60
multiply bot sides by 5/1
5x/5=60 times 5
x times 5/5=300
x times 1=300
x=300
