Weird question.
logically, the only answer that can make sense is a negative one since it is a decreasing slope.
the secant is the average rate of change (and is 1/tangent)
the tangent is the instantaneous rate of change. (1/secant)
we want the first one which is:<span><span><span><span>Δx</span><span>Δy</span></span>=<span><span>Δ weeks</span><span>Δ lbs</span></span>=<span><span>5−0</span><span>137−150</span></span>=<span>5<span>−13</span></span>=−0.3846</span></span>
Answer:
Train got a raise of 16%
Step-by-step explanation:
To find this, start by taking the equation for percent change
(New - Old)/Old * 100 = % Change
Now plug in known values
(580 - 500)/(500) * 100 = % change
80/500 * 100 = % change
.16 * 100 = % change
16 = % change

Answer:
(d) Both sales persons will earn a monthly salary of $5,000 for $25,000 in sales
Step-by-step explanation:
The variable definitions are ...
x = amount of sales
y = monthly earnings
Then the point (x, y) = (25000, 5000) means earnings are $5000 on sales of $25,000.
<u>Complete Question:
</u>
An isosceles triangle has two sides of equal length. The third side is 5 less than twice the length of one of the other sides. If the perimeter of the triangle is 23 cm, what is the length of the third side The third side is described in relation to one of the equal sides, so let x = the length of one of the equal sides. Which equation models the problem?
O x + x + (5 – 2 x) = 23
O x + x + (2 x – 5) = 23
O x + x + (2 x + 5) = 23
O X + (2 x - 5) + (2 x - 5) = 23
<u>Answer:
</u>
The equation models the problem is x + x + (2 x – 5) = 23
<u>Step-by-step explanation:</u>
Given:
An isosceles triangle has two sides of equal length, so let x = the length of one of the equal sides
.
The third side is 5 less than twice the length of one of the other sides. So, the third side is described as 2 x - 5.
The perimeter is the sum of the side lengths and given it as 23. Therefore, form the equation as below,
Perimeter = x + x + (2 x-5)
Given perimeter of triangle = 23 cm. Hence,
x + x + (2 x-5) = 23
The above equation models the given problem.
The lamp is about 90 cm. to get this answer you take 36 and multiply it by 2.5.
