Answer:

the missing leg length is 2√70.

Step-by-step explanation:

This is a right triangle in which the hypotenuse is 19 ft and one of the legs is 9 ft.  Using the Pythagorean Theorem, we find the length of the other leg:

x^2 = (19 ft)^2 - (9 ft)^2 = 361 - 81 = 280, or 4*70

Then the missing leg length is √4√70, or 2√70.

What is 90% written as a decimal rounded to the thousandths place.
USPshnik [31]
     <span> Percents as decimals are that number divided by 100. The rule is to move the decimal 2 places to the left.
.9
.3
1.159
.09
.07
.65
.003
4.45

edit:
None need to be rounded so do you mean given to the thousandth place? In that case the thousandth is 3 decimal slots places to the left so like this:
.900
.300
1.159
.090
.070
.650
.003
4.450</span>

Write the equation of the line in fully simplified slope-intercept form.
hoa [83]

Answer:

y = -x+3

Step-by-step explanation:

Slope intercept form =>  y = mx+b

To find 'm', the slope, pick 2 coordinates.

(0,3)

(2,1)

Use this equation to find the slope using these 2 coordinates: (y1 - y2)/(x1 - x2)

(3 - 1)/(0 - 2) = -1

m = slope = -1

'b' is the y-intersept, or the point when a line passes through the y-axis. That's (0,3).

b = y-intercept = 3

<em>So the equation will be y = -1x + 3, or y = -x + 3</em>

Find the sum of the first 9 terms of the sequence. Show all work for full credit.
Kamila [148]
We can see the sequence goes by decreasing 9 on each number

so the numbers are

2, -7, -16, -25, -34, -43, -52, -61, -70

so adding all these numbers we get

2-7-16-25-34-43-52-61-70

= -306


hope this helped
