Step-by-step explanation:
given,
measures of 3 angles of triangle,
angle 1 = 3x
angle 2 = 2x + 15°
angle 3 = 3x + 5 °
sum of the angles should be 180°
so,
angle 1 + 2 + 3 = 180°
after inserting the values we got,
3x + 2x + 15 + 3x + 5 = 180°
→ 8x + 20 = 180°
→ 8x = 180 - 20 = 160°
→ x = 160/8 = 2
→ x = 20
therefore,
angle
1 = 3x = 3 × 20 = 60
2 = 2x + 15 = 2(20) + 15 = 55°
3 = 3x + 5 = 3(20) + 5 = 65°
as given,
their sum should be 180° so,
60 + 55 + 65 = 180°

So I belive you would divide 8 by 30 then subtract 8 :)
1) given function
y = - 2 ^ ( -x + 2) + 1
2) domain: domain is the set of the x-values for which the function is defined.
The exponential function is defined for all the real numbers, so the domain of the given function is all the real numbers.
3) x-intercept => y = 0
=> y = - 2 ^ ( -x + 2) + 1 = 0 => 2^ ( -x + 2) = 1
=> - x + 2 = 0 => x = 2
The x-intercept is x = 0
4) y-intercept => x = 0
=> y = - 2 ^ ( -x + 2) + 1= - 2 ^ ( 0 + 2) 1 = - (2)^(2) + 1 =- 4 + 1 = - 3
=> The y-intercept is - 3
5) limit when x -> negative infinite
Lim f(x) when x -> ∞ = - ∞
6) limit when x -> infinite
Lim f(x) when x - > infinite = 1
=> asymptote = y = 1
7) range is the set of values of the fucntion: y
Given that the function is strictly decreasing from -∞ to ∞, the range is from - ∞ to less than 1
Range (-∞,1)
Answer:
80.6
Step-by-step explanation:
F = 9/5 C + 32
F = (9/5)*27 + 32 Substitute 27 into the equation
F = 243 / 5 + 32 Multiply 9 and 27 together
F = 48.6 + 32 Divide by 5
F = 80.6 Add on 32
A very quick way to do this is to double your centigrade temperature and and 30 which you should be able to do in your head.
2*27 = 54 Add 30
54 + 30 = 84
This quick way will tell you if you get near the right answer.
Answer:
100% left handed people
20.6% = women
Not women who are left handed
=100-20.6
=79.4%
