Answer:

$4x^2+20x-2$

Step-by-step explanation:

To find (c.g)(x) we basically use the function d(x) as your variable, x, and plug it into c(x). So we replace every x in c(x) with the function d(x), $x^{2} +5x$

c(g(x))=4(x^{2} +5x)-2

c(g(x))4 $x^2$ +20x-2

Jane used $68 more than two-fifths of her last paycheck to purchase a new surfboard. If the surfboard cost $289, find the amount

garri49 [273]

Answer:

552.5

Step-by-step explanation:

2/5x + 68 = 289

2/5 x = 289 - 68

2/5x = 221

x = 221 * 5/2 = 552.5

I hope im right!!!

In the equation 3/4y+1/2=3 1/4, the fractional coefficient is what

AURORKA [14]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

Given equation: $\frac{3}{4}y + \frac{1}{2} = 3 \frac{1}{4}$

In the given equation, $\frac{3}{4}$ is a coefficient and y is the variable.

coefficient is a constant number or quantity multiplied to a variable in an algebric expression. Like in the above equation $\frac{3}{4}$ is a coefficient and y is the variable. We use term variable for y as its value may vary or change. If variable does not have any coefficient in any expression then in that case, we consider 1 as coefficient, for example: $x+4$ , here variable have 1 as coefficient.

Hence, the fractional coefficient is $\frac{3}{4}$ .

A package of modeling clay was shaped like a cone with a radius of 24 cm and a height of 6 cm. Miriam used all the clay to make

Darina [25.2K]

Given:
Cone shape: radius = 24 cm ; height = 6cm
Cylinder: radius = 16cm

We need to find the volume of each shape.

Volume of a cone = π r² h/3 = 3.14 * 24² * 6/3 = 3.14 * 576 * 2 = 3,617.28

Volume of a cylinder = π r² h
3,617.28 = 3.14 * 16² * h
3,617.28 = 3.14 * 256 * h
3,617.28 = 803.84 h
3,617.28 / 803.84 = 803.84h/803.84
4.5 = h

The height of the cylinder is 4.5cm
