2^x * 2 = 15
2^x= 15/2
2^x = 7,5
x = log 2 (7,5)
Answer:
Determine what each letter represents in the Punnett square.
Letters A and B represent the genotypes of the .
Letters C, D, E, and F represent the genotypes of the .
Step-by-step explanation:
$24 is her allowance. 1/3 of her allowance is $8. So you would multiply 8 times 3 because 8 is just 1/3 of her allowance and you want to find her total weekly allowance. 8 x 3 = 24
Answer:
2 is the answer that I would give. The question says <u>distinct</u> solutions does this graph have.
Step-by-step explanation:
You are asked only how many times this crosses the x axis. You are not asked for an exact value. So the thing to do is graph the polynomial.
y = x^3 - 3x^2 + 4
The graph says that x = -1 with a multiplicity of 1
It also says that x=2 is a solution with a multiplicity of 2 (meaning there are 2 roots are the same).
So this polynomial factors into y = (x + 1)(x - 2)(x - 2)
