Answer: 11
Step-by-step explanation:
g(x)=(2x+1)
g(x)=5
g(5)=2(5)+1
=10+1
g(5) =11
Answer: See step by step. Replace the x with theta
Step-by-step explanation: Since sin is less than zero, and secant is positive. This means the trig values are in Quadrant 4.
We know that secФ=17/15. We need to find sin,cos,tan,csc, and cot.
We can find tangent by using the identity
where x is theta.
tan x=
, Tangent in the fourth quadrant is negative so the answer is instead
We can find cotangent by taking the recipocial of tan so
We can find cos by taking reciprocal of sec remeber that cosine is positive in 4th quadrant so the answer is
We can find sin by doing quoteint identies.
To find csc, take reciprocal of sine.
Answer:
(x-2)(x^2+2x+4)
Step-by-step explanation:
x^3-8
x^3-2^3, Now using the base equation for the difference of cubes
(x-y) (x+xy+y^2), y is equal to -2 in this instance.
(x-2)(x+2x+4)
Answer:
AC congruent to EC
Step-by-step explanation:
This problem is asking specifically to prove triangles congruent using HL.
HL is a method of proving triangles congruent. HL stands for Hypotenuse-Leg. If you can show that the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg, respectively, of another triangle, then the triangles are congruent.
Looking at triangle ABC and EDC, we see that the legs AB and ED are congruent. We already have a pair of corresponding congruent legs. Now we need a pair of hypotenuses.
You need AC congruent to EC.
