Answer:
249.45 + 31.75w
Step-by-step explanation:
Opening deposit = $249.45
Weekly deposit made into account = $31. 75
Amount of money which will be in account w weeks after opening :
Opening deposit + (weekly deposit * number of weeks)
Amount after w weeks :
$249.45 + (31.75 * w)
$249.45 + 31.75w
91000
when it says nearest ten you ignore the decimals and look at 90998 the nearest ten of 998 is 1000 so keep the nine at the beginning and you have 91000
<span>1--- f(x) = 4 - 3 sin x = 2
-3 sin x = -2
sin x = 2/3
x ≈ 0.7297276562... ≈ 0.73
2--- -1 ≤ sin x ≤ 1
-3 ≤ 3 sin x ≤ 3
3 ≥ -3 sin x ≥ -3
7 ≥ 4 - 3 sin x ≥ 1
If k < 1 or k > 7, there is no solution.
3--- A = 3π/2
4--- g(x) = 4 - 3 sin x = y
4 - 3 sin y = x
4 - x = 3 sin y
(4 - x)/3 = sin y
sin^-1 (4 - x)/3 = y= g^-1
g^-1 (3) = sin^-1 (4 - 3)/4 = sin^-1 1/4 = 2.8017557... ≈ 2.802

30°
Here's why:
Using the well-known Pythagorian theorem we can reckon how long the hypotenuse is:
c^2=6^2+36*3 -> c=12
Knowing that sin(a)=a/c=6/12=0.5 the measure of the angle in degrees is 30°
Hope could help :)
