Without the image, I assume the two semicircles are on each end of the rectangle.
Rectangle; A = lw
A = 98 x 76
A = 7,448 square meters
Put the two semicircles together to form a circle; A = π
A = (3.14)(
)
A = 3.14 x 76 = 5,776 square meters
7,448 + 5,776 = 13,224 square meters
Answer:
It will be in the air until P(x) is zero.
P(x) = -16x2 + 32x = -16x(x - 2)
P(x) = 0 ⇒ x = 0 or x = 2
It starts on the ground at x = 0, so the total time in the air must be x = 2 seconds.
Answer:
See step-by-step explanation.
Step-by-step explanation:
For the first question, you simply put an EMPTY circle above 2 and draw an arrow from it all the way down to -3. The reason why we put an empty circle is because there is no equal sign below it.
For the second question, you put a FILLED circle above 4 and draw an arrow from it all the way down to -3. The reason why we use a filled circle is because x is less than OR equal to 4.
(3 points) The altitude of a triangle is increasing at a rate of 1 cm/min<span> while the area of the triangle is increasing at a rate of 20 cm2/min. At what rate is the base of the triangle changing when the altitude is 10 cm and the area is 100 cm2. = 2, namely, the base of the triangle is increasing at a rate of </span>2 cm/min<span>.</span>
