Answer:
for x = 0 ; we have f(x) = 0,5
We can eliminate the first and the last proposal because
f(x) = 0,2(0,5ˣ) ⇒ f(0) = 0,2(0,5⁰) = 0,2 × 1 = 0,2 ≠ 0,5
f(x) = 0,2(0,2ˣ) ⇒ f(0) = 0,2(0,2⁰) = 0,2 × 1 = 0,2 ≠ 0,5
Try for x = 1, we have f(x) = 0,1
f(x) = 0,5(5ˣ) ⇒ f(1) = 0,5 × 5 = 2,5 ≠ 0,1
f(x) = 0,2(0,5ˣ) ⇒ f(1) = 0,2(0,5) = 0,1 ⇒ ok
So the answer is f(x) = 0,2(0,5ˣ)
Scalene triangle as there are no sides given.
or,
Measure it using a ruler and classify it based on the result.
Step-by-step explanation:
Scalene triangle = No sides are equal.
Isosceles triangle = 2 sides equal.
Equilateral triangle = All sides equal.
Right angled triangle = One angle is 90.
Since, the picture hasn't given any sides, i am gonna say it's a scalene triangle.
If, the triangle is for measure, measure it using a ruler and classify it based on the result.
B
just because :)
144
x^2+24x=17
b=24
(b/2)^2=(24/2)^2=12^2=144
We know,
so
.....Hope this helps:)
