You're given an angle, the side adjacent to the angle, and are looking for the hypotenuse.

Use cosine = adjacent / hypotenuse.

cos(60) = 2√(3) / x

Rearrange the equation to solve for x (multiply both sides by x, then divide both sides by cos(60)).

x = (2√(3)) / (cos(60))

x equates to about 6.928

Volume of the model:

V=1/3bh= 1/3*100*6= 300 cm³

Density= weight/volume= 300 g/300 cm³= 1 g/cm³

The lowest density is 1 g/cm³

How do u subtract fractions
Gnoma [55]

Like fractions are fractions with the same denominator. You can add and subtract like fractions easily - simply add or subtract the numerators and write the sum over the common denominator.

Before you can add or subtract fractions with different denominators, you must first find equivalent fractions with the same denominator, like this:

1.Find the smallest multiple (LCM) of both numbers.

2.Rewrite the fractions as equivalent fractions with the LCM as the denominator.

When working with fractions, the LCM is called the least common denominator (LCD)

Which exponential function is graphed here?
jek_recluse [69]

Answer:

y = 5^x

Step-by-step explanation:

y= b*(a)^x + c

c could = 1 but then you would not have an exponential function. c = 0 because the graph follows the x axis up until x = -2. Suppose c = 1. The the graph would follow y = 1 up until x = - 2

When x = 0, y = 1 which means that b. If b is anything but 0 or 1 then the y intercept would be stretched to a different place. If be = 0 then y would = 0.

So the graph is of the form y = a^x

Now when x = 0 the graph, the y intercept is y = a^0  or y = 1 So the y intercept is (0,1)

Now the next point is thing to solve for is a.

When x = 1, y = 5  (read the graph)

y = a^x

5 = a^1

5 = a because a^1 is a.

Answer

y = 5^x.

5 = a^1

the telephone company purchased 95 yards of wire for $1235 in september. they plan on making a purchase of 285 yards in October.
Luden [163]
Ratio and propoertion

cost/amount is constant
1235/95=x/285
cross multiply or time both sides by (95 times 283)
351975=95x
divide oth sies by 95
3705=x

the cost is $3705
