I believe the y intercept is 4 but u could be wrong.
the slope is 0.75 or 3/4 (which i’m certain about)

the slope can be found using the slope formula, m= y2-y1/x2-x1

hope this helps :)

A large city in the ancient world was square-shaped. measured in miles, its area numerically exceeded its perimeter by about 132

melisa1 [442]

Area = perimeter + 132.

Let each side of the city be x miles long, then:-

x^2 = 4x + 132
x^2 - 4x - 132 = 0

x = [-(-4) +/- sqrt((-4)^2 - 4 * 1 *-132)] / 2

x = 13.66, -9.66 We ignore the negative

So the city has dimension of 13.66 * 13.66

13.7 * 13.7 to nearest 10th

Circuit Training If sin0 =1 and 0 <0< π find 0.

valkas [14]

Answer:

$\theta = \frac{\pi}{2}$

Step-by-step explanation:

Given

$\sin(\theta) = 1$

$0 < \theta < \pi$

Required

Find $\theta$

$0 < \theta < \pi$ implies that $\theta$ is between 0 and 180 degrees

$\sin(\theta) = 1$

Take arcsin of both sides

$\theta = sin^{-1}(1)$

This gives:

$\theta = \frac{\pi}{2}$

Convert to degrees

$\theta = \frac{\pi}{2} * \frac{180}{\pi}$

$\theta = 90$

We have:

$0 < \theta < \pi$ or $0 < \theta < 180$

To get other values of $\theta$

We use:

$\sin(\theta) = \sin(180 - \theta)$

Substitute: $\theta = 90$

$\sin(90) = \sin(180 - 90)$

$\sin(90) = \sin(90)$

<em>This means that there are no other values of </em> $\theta$ <em> in the given range</em>

Gisele has $5.90 in quarters and nickels. If Gisele has 16 more nickels than quarters, how many quarters does she have? [I don't

Elena-2011 [213]

Answer: There are 17 quarters.

Step-by-step explanation:

Let x = Number of quarters and Number of nickels =x+16

∵ 1 nickel = $0.05, 1 quarter = $0.25

value of x quarters = 0.25 x

value of x+16 nickels = 0.05(x+16)

Then, as per given,

$0.05(x+16)+0.25 x= 5.90 \\\\\Rightarrow\ 0.05x+0.8+0.25x=5.90\\\\\Rightarrow\ 0.30x=5.9-0.8\\\\\Rightarrow\ 0.30x=5.1\\\\\Rightarrow\ x=\dfrac{5.1}{0.30}=\dfrac{51}{3}\\\\\Rightarrow\ x=17$

Hence, there are 17 quarters.
