Pythagorean theorem

marta [7]

Answer:

x = 8

Step-by-step explanation:

$a^{2} +b^{2} =c^{2} \\$ so $8^{2} +b^{2} =\sqrt{80} ^{2}$

rearrange the formula:

$\sqrt{80} ^{2} - 8^{2} = b^{2}$

$80 - 64 = b^2$

$b^2 = 16\\$ $b = \sqrt{16}$

$\sqrt{16} = 4$

$x = 4+4 = 8$

Julian has to read 4 articles for school. He has 8 nights to read them. He decides to read the same number of articles each nigh

daser333 [38]

Answer:

a. He will have to read half an article per night

b. Fraction of the reading assignment read each night = $\frac{0.5}{4}=\frac{1}{8}$

Explanation:

Part a:

We are given that:

number of articles to read = 4 articles

number of nights = 8 nights

To get the number of articles that he should read per night, we will simply divide the the number of articles by the number of nights

Therefore:

number of articles to read per night = $\frac{4}{8}=\frac{1}{2}$ articles per night

Part b:

Now, we know that he will read half an article each night from a total of 4 articles

To get the fraction of the reading assignment read each night, we will divide the number of articles read each night by the total number of assignments

Therefore:

Fraction of the reading assignment read each night = $\frac{0.5}{4}=\frac{1}{8}$

Hope this helps :)

Help! how can i determine the range

djverab [1.8K]

Answer:

$[-1,\infty)$

Step-by-step explanation:

Remember that the range is the set of all y-values. Thus, since the minimum of the function is y=-1, then our range is $[-1,\infty)$ . In interval notation, we use brackets to show what's included and parentheses to show what's not included.
