<h3>given:</h3>

$d = 7 \: ft$

the circumference of the circle.

<h3>solution:</h3>

$c = \pi \: d$

$3.14 \times 7$

$= 21.98 \: ft$

hence, the circumference of the circle is 21.98 feet.

Answer:

$\sf C=21.99~ft.$

__________

$\sf Steps$

$\sf Given~the~diameter~is~7~ft...$

$\sf We~know~we~must~use~diameter-to-circumference~formula$

$\sf Formula:$ $\pi d = \pi * (diameter) = [Circumference]$

__________

$\sf Solve$

$\pi * 7 = 21.99~ft.$

A coin bank has 250 coins, dimes and quarters, worth $39.25. How many of each type of coin are there?

Brilliant_brown [7]

$x-\ number\ of\ dimes\\y-\ number\ of\ quarters\\\\ \left \{ {{x+y=250\ \ \ | x=250-y} \atop {0.1x+0.25y=39.25\ \ \ \ \ \ \ \ \ \ \ \ \ }} \right. \\\\ substitution\ method\\\\
0.1(250-y)+0.25y=39.25\\\\
25-0.1y+0.25y=39.25\\\\
25+0.15y=39.25\ \ \ \ | subtract\ 25\\\\0.15y=14.25\ \ \ \ | divide\ by\ 0.15\\\\y=95\\\\x=250-95=

Identify the type of function represented by each graph

mario62 [17]

Answer:

13. Linear Function

12. Absolute Value Function

11. Quadratic Function

10. Constant and Linear Function

Step-by-step explanation:

13. This graph is in Slope-Intercept Form, $y = mx + b$ . The equation of this line is $y = x + 1$ .

12. This graph obviously is an Absolute Value graph because it is in the shape of a "V".

11. This graph is in the shape of a parabola, so it is considered "Quadratic".

10. This line is constant because it is a horizontal line, but it is ALSO considered a linear function because it is in the form of $y = mx + b$ , and the equation of this line is $y = -2$ , where you have NO rate of change [slope]. This is what you call horizontal lines, zero slopes.
