The area of a triangular flag is 56 square centimeters. It’s altitude is 2 centimeters longer than twice it’s bases find the len

MrMuchimi

Answer:

The length of the altitude is 16 centimeters and the base is 7 centimeters

Step-by-step explanation:

we know that

The area of triangle is equal to

$A=\frac{1}{2}bh$ ----> equation A

where

b is the base and h is the height

$h=2b+2$ ----> equation B

substitute equation B in equation a

$A=\frac{1}{2}b(2b+2)$

we have that

$A=56\ cm^2$

$56=\frac{1}{2}b(2b+2)$

$112=2b^2+2b$

$2b^2+2b-112=0$

solve the quadratic equation by graphing

the solution is b=7 cm

see the attached figure

Find the value of h

$h=2(7)+2=16\ cm$

therefore

The length of the altitude is 16 centimeters and the base is 7 centimeters

Which of the following equations represent nonlinear functions?

s2008m [1.1K]

y=5x^2+7 is Non-Linear Functions

Option B is correct option.

Step-by-step explanation:

We need to identify Non-Linear Functions from the equations given.

First we will define Non-Linear Functions

Linear Functions

A function having exponent of variable equal to 1 or of the form y=c, where c is constant is called linear function.

Non-Linear Functions

A function that has variable having power greater than 1 (i.e 2 or above) is called non-linear function.

So, from all the options given, only Option B has power greater than 1 i.e 2. All remaining options are linear functions.

So, y=5x^2+7 is Non-Linear Functions

Option B is correct option.

In square YOLA, RL=5x+28 and RO=8X-11

Alexeev081 [22]

Answer:

RL=5x+28 and

RO=8X-11

diagonal of square bisect equally the side

:.5x+28=8x-11

11+28=8x-5x

39=3x

x=39/3=13

RY=RL=5x+28=5×13+28=93If the answer is 93, move to answer.
