In a full rotation, 360°, a point on the edge of a gear would travel a distance equal to its circumference. The circumference of a circle is:
C=2πr, and since we are only traveling 150°, we need to set up an appropriate ratio for circumference to the distance the point travels:
d/C=150/360
d=5C/12 and since C=2πr
d=10πr/12
d=5πr/12, and since r=4in
d=5*4π/12 in
d=20π/12 in
d=5π/3 in
d≈5.24 in (to nearest hundredth of an inch)
x is less than or equal to -2.
x is greater than -5.
When x is less than something, the arrow must go left. <———
When x is equal to a number, the dot must be filled in. •
When x is greater than a number, the arrow should go right, toward the greater values. ——>
When x isn’t equal to the number, the circle is not colored in. ⭕️
Shown in picture:
The 40-year-old should have $76800 in capital. The 35-year-old should be saving $$10,320 for retirement.
<h3>How to solve for the amounts</h3>
The capital that a 40 year old has to have with an income of 32000 is
capital income at age 40 * income
= 2.4 * 32000
Capital = $76800
b. At 35 the savings income has to be
percentage of savings income * income
= 12% * $86000
= $10,320
c. There is no specified value for education earnings.
