1 answer:
leva [86]3 years ago
8 0

Answer:

No, because the total will be 3.03 + 0.59 = £3.62

Step-by-step explanation:

0.35 x 3 = 1.05

0.99 x 2 = 1.98

1.05 + 1.98 = 3.03 = $3.03 without pencil (0.59)

= 1.05 + 1.98 = 3.03 ≤ 3 is incorrect as 3.03 should be the maximum equal to or appear the other way round.

Inequality for all 6 items using the same inequality shown 0.35x+0.99y+0.59< 3 is incorrect No, because the total will be 3.03 + 0.59 = £3.62

and inequality of higher amounts than $3 should be shown other way round where ≤ 3 means it stops at $3 and is less or equal.

and inequality facing towards means it would be equal but more than $3

What is the maximum height of of Anna's golf ball? The equation is y=x−0.04x2.
elena-s [515]

Given:

The height of a golf ball is represented by the equation:

y=x-0.04x^2

To find:

The maximum height of of Anna's golf ball.

Solution:

We have,

y=x-0.04x^2

Differentiate with respect to x.

y'=1-0.04(2x)

y'=1-0.08x

For critical values, y'=0.

1-0.08x=0

-0.08x=-1

x=\dfrac{-1}{-0.08}

x=12.5

Differentiate y' with respect to x.

y''=(0)-0.08(1)

y''=-0.08

Since double derivative is negative, the function is maximum at  x=12.5.

Substitute x=12.5 in the given equation to get the maximum height.

y=(12.5)-0.04(12.5)^2

y=12.5-0.04(156.25)

y=12.5-6.25

y=6.25

Therefore, the maximum height of of Anna's golf ball is 6.25 units.
