Answer:
- 3.46 pounds
- 6.92 pounds
- 13.84 pounds
Step-by-step explanation:
The most accurate ratio of pounds to dollars will be found using the given numbers that have the most significant figures. Those are found on the last row of the table:
pounds/dollar = 34.60/50 = 0.692
To find the other table values, multiply the dollar amounts by this constant of proportionality. The problem statement tells you to round the result to hundredths.
$5 ⇒ 5.00 × 0.692 = 3.46 pounds
$10 ⇒ 10.00 × 0.692 = 6.92 pounds
$20 ⇒ 20.00 × 0.692 = 13.84 pounds
_____
You can also fill in the table by recognizing that $5 is one tenth of $50, so the number of pounds will be one tenth of 34.60 = 3.46. Then each of the following rows doubles the amount on the previous row.
The slope is the change in Y divided by the change in X.
You would need to know the coordinates of 2 points ( X1,Y1) and (X2,Y2), then subtract : Y2 - Y1 divided by X2- X1.
Look at ur line starting at point G....it goes up a little, then goes down...therefore, it increases, then decreases
Answer:
11.33 feet
Step-by-step explanation:
The triangle for the given scenario is drawn below.
From the triangle ΔABC, AB is the length of the ladder, B is the foot of the ladder, AC is the wall, BC is the distance of the foot from the wall, and angle B is the angle of elevation of the ladder with ground.
Let the length of the ladder, ![AB = x](https://tex.z-dn.net/?f=AB%20%3D%20x)
As per question, BC = 6.5 ft,
°
Using cosine ratio of the angle B, we get
![\cos 55=\frac{BC}{AB}\\\\\cos 55=\frac{6.5}{x}\\\\x=\frac{6.5}{\cos 55}=11.33\textrm{ ft}](https://tex.z-dn.net/?f=%5Ccos%2055%3D%5Cfrac%7BBC%7D%7BAB%7D%5C%5C%5C%5C%5Ccos%2055%3D%5Cfrac%7B6.5%7D%7Bx%7D%5C%5C%5C%5Cx%3D%5Cfrac%7B6.5%7D%7B%5Ccos%2055%7D%3D11.33%5Ctextrm%7B%20ft%7D)
Therefore, the length of the ladder is 11.33 ft.
