Answer:
the width=15; the length=20
Step-by-step explanation:
1. to solve the given equation: x²+5x-300=0;
x₁= -20; x₂=15, where 'x' can be only positive value. It means x=15;
2. according to the condtition the length is more, it means 15+5=20.
3. the width is x=15; the length is 20.
Answer:
The answer is c
Step-by-step explanation:
You have to do everything backwards,
-9 divide it by 3 to get -3, then add seven to that answer
Answer:
f(g(-4)) = 13.
g(f(-4)) = -3.
Step-by-step explanation:
g(-4) = (-4)^2 + 3(-4) - 1
= 3.
so f(g(-4))
= f(3)
= 2(3) + 7
= 13.
f(-4) = 2(-4) + 7
= -1.
so g (f(-4))
= g(-1)
= (-1)^2 - 3 - 1
= -3.
1. -10/9
2. 2/5
3. -2/5
4. 3/5
5. 1/10
6. -10/3
Given that the point (12,-5) which takes the form (x,y), This implies that:
opposite=-5
adjacent=12
thus using using Pythagorean theorem, the hypotenuse will be:
c^2=a^2+b^2
plugging the values we obtain:
c^2=(12)^2+(-5)^2
c^2=144+15
c^2=169
thus
c=13
but
cos θ=adjacent/ hypotenuse
therefore:
cos θ=12/13
Answer is option . D
