The m∠ U is 72°.
Step-by-step explanation:
Given:
To find :
Solution:
The sum of the measures of the interior angles of a polygon with 'n' sides is given as
Here we have n = 5 on substituting the values we get
Therefore,
m∠ U is 72°.
Answer:
A.
Step-by-step explanation:
I gotchu fam. The first thing that you would want to do is find the slope. The slope is the change in y divided by the change in x. Based on the points on the line, the change in y is 2 because it goes up two, and the change in x is one because it goes over 1. This would make your slope 2/1, or just 2! Now we have our slope, so we want to find our y-intercept. There are two ways that we can do this. The first way is just eyeballing it, but sometimes that's not always accurate. We're just going to do that because its faster (lol). It looks around -2. With this information, we have our entire equation! y=mx+b. we can plug in our information. y=2x-2. And that's how your answer's A! Hope this helps.
Answer:
y = 1%
Step-by-step explanation:
From the formula;
Interest; i = PRT/100
P = £5000
R = 10%
After 1 year, we have;
i = 5000 × 10 × 1/100 = £500
Amount is now; 5000 + 500 = £5500
Since interest rate is now y% every year after the first one, then;
After 2nd year;
i = (5500 × y × 1)/100
i = 55y
So amount is now;
5500 + 55y
After 3rd year, interest is now;
i = (5500 + 55y) × y × 1/100
i = 55 + 0.55y²
Amount is now;
(5500 + 55y) + (55 + 0.55y²)
Since she has £5610.55 after 3 years, then;
(5500 + 55y) + (55 + 0.55y²) = 5610.55
0.55y² + 55y + 5555 - 5610.55 = 0
0.55y² + 55y - 55.55 = 0
From quadratic formula, y = 1%
