Find the equation of the sphere centered at (2,−9,1) with radius 2. 4 = (x-2)+(y+9)+(z-1). Give an equation which describes the

Monica [59]

Answer:

See explanation

Step-by-step explanation:

The equation of the shpere canterd at point $(a,b,c)$ with radius $R$ is

$(x-a)^2+(y-b)^2+(z-c)^2=R^2$

The center of the sphere is (2,-9,1), the radius is 2, then the equation is

$(x-2)^2+(y+9)^2+(z-1)^2=2^2\\ \\(x-2)^2+(y+9)^2+(z-1)^2=4$

Now, find the intersection of this sphere with the plane z=2. Substitute 2 instead of z into the sphere equation:

$(x-2)^2 +(y+9)^2+(2-1)^2=4\\ \\(x-2)^2+(y+9)^2+1=4\\ \\(x-2)^2+(y+9)^2=3$

This is the equation of the circle lying in the plane z=2 with center at (2,-9,2) and radius $\sqrt{3}.$

A watermelon is launched from a 25-foot tall platform at a carnival. The watermelon's height h (in feet) at time t seconds can b

Nataly [62]

Answer:

The maximum height of the watermelon is 74 feet.

Step-by-step explanation:

The watermelon reaches its maximum height when its velocity is zero. Mathematically speaking, velocity is the first derivative of the function height, that is:

$v(t) = \frac{d}{dt} h(t)$ (1)

Where $v(t)$ is the velocity, in feet per second.

If we know that $h(t) = -16\cdot t^{2}+56\cdot t +25$ and $v(t) = 0\,\frac{ft}{s}$ , then the time associated with maximum height is:

$v(t) = -32\cdot t +56$ (2)

$-32\cdot t + 56 = 0$

$t = 1.75\,s$

Now we evaluate the function height at time found in the previous step: ( $t = 1.75\,s$ )

$h(t) = -16\cdot t^{2}+56\cdot t +25$

$h(1.75) = 74\,ft$

The maximum height of the watermelon is 74 feet.

<1 and <2 are vertical angles. If the measure of <2 is 105°, find the measure of <1.

umka21 [38]

Answer:

105°

Step-by-step explanation:

This is most likely the answer if the lines are perpendicular... But if It doesn't give you an image of the 2 angles, then the answer is 105°

Which quadratic equation has roots - 2 and 1/5 :

Sladkaya [172]

Answer:

$5 {x}^{2} \: + \: 8x \: - 2 \: = \: 0$

Step-by-step explanation:

$sum \: of roots = - 2 + \frac{1}{5} = - \frac{8}{5} \\ product \: of \: roots = - 2 \times \frac{1}{5} = - \frac{2}{5} \\ from \: general \: equation \\ a {x}^{2} + bx + c = 0 \\ {x}^{2} + \frac{8}{5} x \: - \frac{2}{5} = 0 \\ 5 {x}^{2} \: + \: 8x \: - 2 \: = \: 0$
