Answer:
$ 22.22
Step-by-step explanation:
Let
P = amount to save per week
B = expected accurate at 16 years = $5000
r = APR = 3.9% = 0.039
n = numbers of week in a year = 52weeks
t = 16 - 12 = 4 years terms of savings.
Using,
P = (B * r/n)/{(1 + (r/n))^(nt) -1}
P = (5000 * 0.039/52)/{(1 + (0.039/52))^(52 * 4) -1}
P = $22.22
Answer:
X<2
Step-by-step explanation:
2x+4<8
subtract 4 from both sides
2x+4-4<8-4
simplify
2x<4
divide both by 2
2x/2<4/2
x<2
Answer:
1) triangles are similar
Step-by-step explanation:
The height from vertex X of isosceles ∆WXY is 4 units. The width WY is also 4 units. In isosceles ∆UVW, the height from vertex V is 6 units, and the width UW is also 6 units.
The height ratios are ...
∆WXY/∆UVW = 4/6
The width ratios are ...
∆WXY/∆UVW = 4/6
The measures of ∆WXY are proportional to those of ∆UVW, so the triangles are similar.
_____
Strictly speaking, you cannot go by triangle height and width alone. That is why we made not of the fact that the triangles are <em>isosceles</em>. When base and height of an isosceles triangle are proportional, the Pythagorean theorem guarantees that side lengths are proportional. Trigonometry can also be invoked to support the claim that angles are congruent.
Answer:
A line of best fit is a straight line going through a trend on a scatter plot.
Step-by-step explanation:
A well drawn line of best fit is just a line going straight through the trend of dots to approximate an exact trend from a non-exact plot, so just draw a line that stays in the middle of the dots and you should do great.
Hope this helped!
