Answer:

(h+k)(2) = 5

(h-k)(3) = 9

3h(2) + 2k(3) = 17

Step-by-step explanation:

(h+k)(2)

h(2) + k(2) = ((2)²+1) + ((2)-2) = 5 + 0 = 5

(h-k)(3)
h(3) - k(3) = ((3)²+1)-((3)-2) = 10 - 1 = 9

3h(2) + 2k(3)
3(5) + 2(1) = 15 + 2= 17

if PQ || RS and the slope of PQ= x-1/4 and the slope of RS is 3/8 then find the value of x justify algebraically and numerically

Artemon [7]

The value of x is 5/8.

<u>Step-by-step explanation</u>:

Given,

The lines PQ and RS are parallel to each other.
slope of PQ= x-1/4
slope of RS = 3/8

The slopes of parallel lines are equal.

slope of PQ = slope of RS

⇒ x-1/4 = 3/8

⇒ (4x-1)/4 = 3/8

⇒ 8(4x-1) = 4(3)

⇒ 32x-8 = 12

⇒ 32x = 20

x = 20/32

x = 5/8

Answer:

Large baking dish of cylinder, cone and sphere.

Step-by-step explanation:

When we compute the volume of each of the small and large baking dish taking $\pi$ =3.14, we get

Volume of cylinder (small dish)= $\pi$ (r^2)(h)

=3.14( $\frac{3}{2}$ )^2*3

= $\frac{3.14*9*3}{4}$

= 21.195

Volume of cylinder (large dish)= $\pi$ (r)^2(h)= 3.14*(3)^2(3)

=84.78

Similarly, volume of cone (smaller dish)= $\frac{1}{3} \pi r^{2} h$

= 7.065

Volume of cone (larger dish)= 84.78

Volume of sphere(smaller dish)= $\frac{4}{3} \pi r^{3}$

= 14.13

Volume of sphere (larger dish) = 85.17 (approx)

Hence, we get that larger baking dish have approximately same volume.

Therefore, large baking dish of cylinder, cone, sphere will be chosen.
