Y = -x^2 + x + 2
y = -x + 3
-x + 3 = -x^2 + x + 2
x^2 - x - 2 - x + 3 = 0
x^2 -2x + 1 = 0
(x - 1)(x - 1) = 0
x - 1 = 0 y = -x + 3
x = 1 y = -1 + 3
y = 2
solutions are : (1,2) , (1,2)
Answer: 3/8 yard
Step-by-step explanation:
Since the beetle crawled 1/2 of a yard and the spider crawled 1/8 of a yard. To calculate how much farther the beetle crawl than the spider, we will have to subtract 1/8 from 1/2. This will be:
= 1/2 - 1/8
= 4/8 - 1/8
= 3/8 yard
Therefore, the beetle covered 3/8 yard more.

Remember the difference quotient
the deritivie of f(x)/g(x) is
so
q'(7)=
g(7)=2.5
g'(7)=0.5
f(7)=5
so
q'(7)=
q'(7)=
now find the slope of f(x) at x=7
take the deritive and evaluate
(try googling a deritive calculator)
or just ask me
basically
the answer is
just find the slope of f(x) at x=7 (that is the slope at that specitific point, not for the whole graph)
Answer:
[(√2)^√2]^√2 = 2¹ = 2
Step-by-step explanation:
Hi there!
Let´s write the expression:
[(√2)^√2]^√2
Now let´s rewrite it using fractional exponents (√2 = 2^1/2):
[(2^1/2)^2^1/2]^2^1/2
Let´s use the following property of exponents: (xᵃ)ᵇ = xᵃᵇ and multiply the exponents:
1/2 · 2^1/2 · 2^1/2
Now, let´s use the following property of exponents: xᵃ · xᵇ = xᵃ⁺ᵇ
1/2 · 2^(1/2 + 1/2) = 1/2 · 2¹ = 1
Then, the expression can be written as:
[(√2)^√2]^√2 = 2¹ = 2
Have a nice day!
