Answer:

13

Step-by-step explanation:

In this concept, it forms a right triangle because it is 5 feet high, the base is 12 feet horizontally, and you need to find the hypotenuse (the longest side of the triangle/the slanted side). In this case, you can use the Pythagorean Theorem, which is a^{2}+b^{2}=c^{2}, where <em>a</em> and <em>b</em> are the lengths of the triangle, and <em>c </em>is the hypotenuse.

-We know <em>a </em>and <em>b </em>already, which are 5 and 12. So substitute <em>a </em>and <em>b </em>in the equation:  5^{2}+12^{2}=c^{2}

-Then, simplify to get:  25+144=c^{2}

-Add the 25 and 144 to then get:  169=c^{2}

-Find the square root of both sides to only get <em>c</em> left (the hypotenuse): \sqrt{169}=\sqrt{c^{2}}

-Then you’ll get: \sqrt{169}=c, which simplifies to 13=c

<u>ANSWER: 13</u>

Answer:

5^2+12^2= c^2

25+144=c^2

169=c^2

find the square root of 169

the length is = 13 ft

The line represented by the equation 4y + 2x = 33.6 shares a solution point with the line represented by the table
mamaluj [8]

Answer:

The solution of this system is

(4). (6.0,5.4)

Step-by-step explanation:

First we have to find the equation of the line represented in the table; for that we have to find it's slope m and it's y-intercept b and then write it in the following form:

y=mx+b

The slope m of the line we get from first two points:

m=\frac{3.8-3.2}{(-2)-(-5)} =0.2

thus we have

y=0.2x+b

we find b by putting the point (2,4.6) into the function:

4.6=0.2(2)+b

b=4.6-0.4=4.2

Thus we have

y=0.2x+4.2

Now we have to find where this line intersects with 4y+2x=33.6; to do this we just substitute y with y=0.2x+4.2:

4(0.2x+4.2)+2x=33.6

0.8x+16.8+2x=33.6

\boxed{x=6 }

<em>We have the x-coordinate of  the intersection.</em>

We find the y-coordinate by substituting x=6 into y=0.2x+4.2:

y=0.2(6)+4.2=5.4

\boxed{y=5.4}

Thus the solution to the system is

\boxed{(x,y)=(6, 5.4)}

which is option 4.

Suppose y is inversely proportional to x. When x is 0.5, y is 12. What is the rule for the inverse variation?
Korvikt [17]
We know that
if <span>y is inversely proportional to x
then
y=k/x
where k is the constant of variation
so
for x=0.5  y=12
find the value of k
12=k/0.5-----> k=12*.5----> k=6
y=6/x

the rule is the following
y=6/x
