Answer:
option C and F
Step-by-step explanation:
Given excluded value is x=-5
Excluded value are the values that makes the denominator 0
Now we check out each option and see , in which option the denominator becomes 0 when x=-5
When denominator has (x+5) then when we plug in x=-5
(x+5) becomes (-5+5) =0
So we look at the options that has factor (x+5) in the denominator
In option C we have x^2 -25
When we plug in -5 for x then it becomes (-5)^2 - 25 =0
So x=-5 makes the denominator 0
-5 is an excluded value for option C
Last option f has x+5 in the denominator
x=-5 make the denominator 0
so , -5 is an excluded value for option F
Answer:
B(3.5, 0.5)
Step-by-step explanation:
Given:
A(5,5), Xa=5, Ya=5
C(3,-1), Xc=3, Yc=-1
To find point B, we can use the partition rule, where AB = 3BC, so AB occupies k=3/4 of the distance AC.
B(x,y) = ((1-k)Xa+kXc, (1-k)Ya+kYc)
=(Xa/4+3Xc/4, Ya/4+3Yc/4), substitute values
=(5/4+3*3/4, 5/4+3*(-1)/4)
=(14/4,2/4)
=(3.5, 0.5)
The odds are 3/6. They are equal to the odds of the odd numbers.
You have to find the cos of angle A, so use the Pythagorean equation and trig laws to find the other side of the triangle created by angle A. 3^2 + x^2 = 5^2. x=4. This means cos(A) = 4/5). Make both cos (A) and cos (B) have equal denominators, and add. 148/185 + 60/185 = 208/185. This answer is correct, though it doesn’t appear to be any of the answers you wrote, so either those answers are wrong or you wrote something incorrectly in the problem.
It is in simplest form. Decimal form is 14.4
