If EH = 76, calculate DI.

Montano1993 [528]

Answer:

DI = 38

Step-by-step explanation:

Δ EHC and Δ DIC are similar and ratios of corresponding sides are equal, that is

$\frac{DI}{EH}$ = $\frac{DC}{EC}$ , substitute values

$\frac{DI}{76}$ = $\frac{1}{2}$ ( cross- multiply )

2DI = 76 ( divide both sides by 2 )

DI = 38

Write the equation of a line that is perpendicular to y=7x−2 and passes through the point (14,8).(1 point) y=7x−90 y=10x−17 y=−1

True [87]

Answer:

$\huge\boxed{y=-\frac{1}{7}x+ 10}$

Step-by-step explanation:

In order to find the equation of this line, we need to note two things.

A) The slope of two lines that are perpendicular will be opposite reciprocals (that is, multiplying them gets us -1.)
B) We can substitute a point inside an incomplete equation to try and find a missing value.

So first, let's find the opposite reciprocal of 7 which will be the slope to this equation.

<u>Reciprocal of 7:</u> $\frac{1}{7}$
<u>Opposite of </u> $\frac{1}{7}$ : $-\frac{1}{7}$

So the slope of this line will be $-\frac{1}{7}$ . The y-intercept will change, and we can substitute what we know into the equation $y=mx+b$ .

$y = -\frac{1}{7}x+b$

Now, we can substitute a point on the graph (14, 8) into this equation to find b.

$8 = -\frac{1}{7} \cdot 14 + b$
$8 = -\frac{14}{7} + b$
$8 = -2 + b$
$b = 10$

Now that we know the y-intercept, we can finish off our equation by plugging that in.

$y = -\frac{1}{7}x + 10$

Hope this helped!

A rectangular floor space in a community center is 40 ft long and 32 ft wide. A volunteer is setting up chairs on the floor spac

pav-90 [236]

It is B because 40x32=1280 and 5x4=20 then divide 1280 by 20 and you get 64 but you can’t have 64 so you would need to only have 60 so the answer is B

F(t) = -2t + 5 f() = 13

fomenos

Answer:

I don't know what the question is but...

Step-by-step explanation:

-2t+5-13= -2t-8

-2t+5+13=-2t+18

-2t+5*13= -2t+65

-2t+5/13= -26t-5/13
