What is the product 3x5(2x2+4x+1)

lesya692 [45]

Answer:

$6x^7+12x^6+3x^5$

Step-by-step explanation:

The given expression is:

$3x^5(2x^2+4x+1)$

We expand the parenthesis using the distributive property to obtain;

$3x^5(2x^2)+3x^5(4x)+3x^5(1)$

Recall that;

$a^m\imes a^n=a^{m+n}$

We apply this property and multiply out the constant terms to obtain;

$6x^7+12x^6+3x^5$

Find the equation of the linear function represented by the table below in slope-intercept form.

Y_Kistochka [10]

Answer:

y= 8x +7

Step-by-step explanation:

slope-intercept form:

y= mx +c, where m is the gradient (or slope) and c is the y-intercept.

Since it is a linear function, the gradient of any 2 points would be equal.

$gradient = \frac{y1 - y2}{x1 - x2}$

Thus, gradient of the line

$= \frac{39 - 23}{4 - 2} \\ = \frac{16}{2} \\ = 8$

Subst. m=8 into the equation:

y= 8x +c

To find the value of c, substitute a pair of coordinates.

When x=0, y= 7,

7= 8(0) +c

c= 7

Thus, the equation of the linear function is y= 8x +7.

Answer:

Inequality: 6r - 200 - 65 $\geq$ 1000 and minimum of 211 people

Step-by-step explanation:

Let r = rides

6r - 200 - 65 $\geq$ 1000

6r - 265 $\geq$ 1000

6r $\geq$ 1265

r $\geq$ 210 $\frac{5}{6}$

Needs 211 people to make a profit of at least $1000
