Jennifer has 12 nickels and dimes. The value of her coins is $1

ELEN [110]

Answer:

One Dollar and 80 cents.

Step-by-step explanation:

12 x 5 is 60. The amount of nickles multiplied by the value of one nickel which is 5 cents. Then you take the value of a dime and multiply it by the amount of dimes, 12. You get 120. Add 60 to 120 and you get 180. One Dollar is 100 cents, add 80 to 100 and you get one Dollar and 80 cents.

Jeanine’s swimming pool has a diameter of 27 feet. Surrounding the pool is a

Anuta_ua [19.1K]

Answer:

It will cost $427.04 to paint deck and it will cost 958.485 to add fencing around deck

Step-by-step explanation:

Diameter of swimming pool = 27 feet

Radius of pool r= $\frac{27}{2}=13.5 feet$

Surrounding the pool is a deck that extends 5 feet from the edges of the pool

Outer radius R = 13.5+5=18.5

Area of deck = Outer area - Inner area

Area of deck = $\pi R^2 -\pi r^2$

Area of deck = $3.14(18.5^2-13.5^2)$

Area of deck = $502.4 ft^2$

Cost of painting 1 sq.feet = $0.85

Cost of painting 502.4 sq.feet = $502.4 \times 0.85=427.04$

Perimeter of deck = $2 \pi R = 2 \times 3.14 \times 18.5 =116.18 feet$

Cost of fencing 1 foot = $8.25

Cost of fencing 116.18 foot = $116.18 \times 8.25=958.485$

Hence it will cost $427.04 to paint deck and it will cost 958.485 to add fencing around deck

The 3rd degree Taylor polynomial for cos(x) centered at a = π 2 is given by, cos(x) = − (x − π/2) + 1/6 (x − π/2)3 + R3(x). Usin

Otrada [13]

Answer:

The cosine of 86º is approximately 0.06976.

Step-by-step explanation:

The third degree Taylor polynomial for the cosine function centered at $a = \frac{\pi}{2}$ is:

$\cos x \approx -\left(x-\frac{\pi}{2} \right)+\frac{1}{6}\cdot \left(x-\frac{\pi}{2} \right)^{3}$

The value of 86º in radians is:

$86^{\circ} = \frac{86^{\circ}}{180^{\circ}}\times \pi$

$86^{\circ} = \frac{43}{90}\pi\,rad$

Then, the cosine of 86º is:

$\cos 86^{\circ} \approx -\left(\frac{43}{90}\pi-\frac{\pi}{2}\right)+\frac{1}{6}\cdot \left(\frac{43}{90}\pi-\frac{\pi}{2}\right)^{3}$

$\cos 86^{\circ} \approx 0.06976$

The cosine of 86º is approximately 0.06976.

Point P partitions the directed segment from A to B into a 1:3 ratio. Q partitions the directed segment from B to A into a 1:3 r

olga2289 [7]

Answer:

c)No, P is the distance from A to B, and Q is the distance from B to A.

Step-by-step explanation:

Point P partitions the directed segment from A to B into a 1:3 ratio.

Ratio is 1:3

So AP is 1 and PB is 3

Q partitions the directed segment from B to A into a 1:3 ratio.

Ratio is 1:3

So BQ is 1 and QA is 3.

That is AQ= 3 and BQ= 1

The ratio of Q and P varies

AP =1 and AQ=3

So P and Q are not at the same point.

Because P is the distance from A to B and Q is the distance from B to A
