The question is Let h(x)=2x+5 and <span>g(x)=8-3x
what is the value of </span><span>h(g(1.5))
the answer
</span>h(g(1.5))= 2g(1.5)+5, and <span>g(1.5)=8-3(1.5)=3.5, so
</span>h(g(1.5))= 2<span>(3.5)+5= 12
</span>h(g(1.5))= 12
He will have more than enough because he only needs to cover 84.1425 square feet.
Answer:
Each point (or pair) in a proportional relationship must share the same ratio.
Step-by-step explanation:
a proportional relationship must share the same ratio in order to be proportional it doesn't madder in what way it is proportional.
Answer:
3.10 * 72
Step-by-step explanation:
To find 310% of 72
Of means multiply and is means equal
310% * 72 = answer
Change to decimal form
3.10 * 72 = answer
223.20
(9,40,41) is a Pythagorean Triple, farther down the list than teachers usually venture.
Answer: D. 41 cm
There's a subset of Pythagorean Triples where the long leg is one less than the hypotenuse,
a^2+b^2 = (b+1)^2
a^2 + b^2 = b^2 + 2b +1
a^2=2b+1
So we get one for every odd number, since the square of an odd number is odd and the square of an even number is even.
b = (a^2 - 1)/2
a=3, b=(3^2-1)/2=4, c=b+1=5
a=5, b=(5^2-1)/2 =12, c = 13
a=7, b=24, c=25
a=9, b=40, c=41
a=11, b=60, c=61
a=13, b=84, c=85
It's good to be able to recognize Pythagorean Triples when we see them.
Otherwise we'd have to work the calculator:
√(9² + 40²) = √1681 = 41
