Changing the y-coordinates will make all coordinates negative and give us an image, or reflection, in the third quadrantSwitching the coordinates will flip the figure back to the right orientationEach coordinate (x,y) is changed to (-y,-x)This is our general formula for rotating the figure 270 degrees about the origin .Changing the y-coordinates will give us an image in the third quadrantIn other words, it will be a reflection of the figure in the second quadrant Switching the coordinates will flip the figure back to the right orientation Each coordinate (x,y) is changed to (-y,-x)This is our general formula for rotating the figure 270 degrees about the origin

Sandra throws an object straight up into the air with initial velocity of 38 ft per square from platform that is 30 ft above the

expeople1 [14]

Answer:

3 seconds.

Step-by-step explanation:

We have been given that Sandra throws an object straight up into the air with initial velocity of 38 ft per second from platform that is 30 ft above the ground.

To find the time it will take for object to hit the ground, we will use formula:

$h(t)=-16t^2+v_0t+h_0$ , where, $v_0$ represents initial velocity and $h_0$ represents initial height.

Upon substituting our given initial velocity and initial height, we will get:

$h(t)=-16t^2+38t+30$

We know that object will hit the ground, when height will be 0, so we will equate object's height equal to 0 and solve for t as:

$-16t^2+38t+30=0$

Divide by 2:

$-8t^2+19t+15=0$

Upon using quadratic formula, we will get:

$t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}=\frac{-19\pm\sqrt{19^2-4(-8)(15)}}{2(-8)}$

$t=\frac{-19\pm\sqrt{361+480}}{-16}=\frac{-19\pm\sqrt{841}}{-16}$

$t=\frac{-19\pm29}{-16}$

$t=\frac{-19-29}{-16},t=\frac{-19+29}{-16}$

$t=\frac{-48}{-16},t=\frac{10}{-16}$

$t=3,t=-\frac{5}{8}$

Since time cannot be negative, therefore, it will take 3 seconds for object to hit the ground.

I need help I will give BRAINLEST

GREYUIT [131]

Answer:

25%

Step-by-step explanation:

To solve this, we can use the percent change formula shown in the picture attached below. $x_{2}$ is the new value, $x_{1}$ is the old value, and $C$ represents the change. For this problem, 80 is the new value and 64 is the old value. Let's plug those numbers into the formula and solve for the percent change:

$C = \frac{(80-64)}{64} \\$ × $100$

$C = \frac{16}{64}$ × $100$

$C = 0.25$ × $100$

$C = 25%$

Thus, the answer is 25%.
