Using it's concept, it is found that the coefficient of the mathematical expression 7m² + 2(19) is of 7.

<h3>What is the leading coefficient of a polynomial?</h3>

The leading coefficient of a polynomial is the <u>term that multiplies the highest exponent</u>.

In this problem, the expression is given by:

7m² + 19.

The highest exponent is of 2, in m², hence the leading coefficient is of 7.

The function h(x)=4/3x-1 represents the composite h(x)=f(g(x)).if f(x)=2x-1,what is g(x)

Hunter-Best [27]

Answer:

$g( x) = \frac{2}{3}x$

Step-by-step explanation:

Given:

Composite Function:

$h( x)=f( g( x))$

Also,

$h( x)=\frac{4}{3}x-1$

To find:

$g( x ) = ?$

Solution:

First of all, let us learn about a composite function.

Composite function $f( g( x))$ means to write $g( x)$ in place of $x$ in the function $f( x)$ .

Let $g( x) = y$

So, $f( g( x))$ = $f( y )$ .

Therefore,

$h( x) =f( g( x)) = f( y)$

So, $f( y) = 2y-1$

We have to solve for $y$ in terms of $x$ to find the value of $g(x)$ :

$\Rightarrow \frac{4}{3}x-1 = 2y-1\\\Rightarrow 2y=\frac{4}{3}x\\\Rightarrow y = \frac{2}{3}x$

Hence, the answer is $g( x ) = \frac{2}{3}x$ .

Checking whether the answer is correct or not:

$f( g( x)) = f( \frac{2}{3}x) = 2\times \frac{2}{3}x -1 = \frac{4}{3}x-1$

which is $h( x)$ .

Hence, our answer $g( x ) = \frac{2}{3}x$ is correct.

1/4 of a rod was painted red. 2/5 was painted orange and 2/7 of the remainder was painted yellow. The yellow section was 20cm lo

Leno4ka [110]

Answer: 200cm long

Step-by-step explanation:

Let the length of the rod be x

red = 1/4 of the rod , which means 1/4 of x

orange = 2/5 of x

The remainder = x - ( $\frac{x}{4}$ + $\frac{2x}{5}$ )

= x - ( $\frac{13x}{20}$ )

= $\frac{7x}{20}$

yellow = 2/7 of the remainder , that is

yellow = 2/7 of $\frac{7x}{20}$

yellow = $\frac{x}{10}$

and it was given that the yellow section was 20cm long , that is

$\frac{x}{10}$ = 20cm

x = 20 x10

x = 200

Therefore the rod was 200cm long

If log10x=−3 , what is the value of x ?

IgorC [24]

log10x=−3

10 ^(log10x) = 10^(-3)

10x = 10^-3

x =10 ^ -3 / 10

x = 10^-4

x = .0001

x=1/ 10000

Help me find domain? Please

dedylja [7]

This graph is that of a parabola, which in turn represents a quadratic (2nd order) equation, also a polynomial. The domain of any and all polynomial(s) is "the set of all real numbers," or (-infinity, infinity).
