( please help I really need it )Joan represents the height at which a sea gull is flying at +4 feet and the depth at which a fis

h is swimming at −3 feet on a number line, where 0 represents the surface of the water. Which of these explains whether the sea gull or the fish is closer to the surface of the water?
The fish is closer to the surface of the water because |+4| = 4 and |−3| = 3, and 3 < 4.


The fish is closer to the surface of the water because |+4| = 4 and − |−3| = −3, and −3 < 4.


The sea gull is closer to the surface of the water because |+4| = −4 and |−3| = −3, and −3 > −4.


The sea gull is closer to the surface of the water because |+4| = 4 and − |−3| = 3, and 4 > 3.

Answer:

The fish is closer to the surface of the water because |+4| = 4 and |−3| = 3, and 3 < 4.

Step-by-step explanation:

The answer is this because they are finding the absolute value. Because 3 is less than 4, that means that it isn't as far away from zero on the number line. This is the only answer where the absolute value and the object is correct.

IgorC [24]

Answer:

a) Here we have:

"In Family A, the youngest child is 7 years younger than the oldest, who is 18"

Let's define:

Y = age of the youngest child.

O = age of the oldest child.

Then we know that:

Y = O - 7

O = 18

Then we can replace the second equation into the first one:

Y = 18 - 7 = 11.

b) Here we have:

"In Family B, the middle child is 5 years older than the youngest child."

Let's define:

Y = age of the youngest child.

M = age of the middle child.

Here we have only one equation:

M = Y + 5.

Demand The demand function for the product is given by
DiKsa [7]

Answer:

(a) 2996 units

(b) 1897 units

Step-by-step explanation:

p = 10,000(1 - 3/3 + e^-0.001x)

(a) p = $500

500 = 10,000(1 - 1 + e^-0.001x)

500/10,000 = e^-0.001x

e^-0.001x = 0.05

-0.001x = In 0.05 = -2.996

x = -2.996/-0.001 = 2996 units

(b) p = $1500

1500 = 10,000(1 - 3/3 + e^-0.001x)

1500/10,000 = (1 - 1 + e^-0.001x)

0.15 = e^-0.001x

-0.001x = In 0.15 = -1.897

x = -1.897/-0.001 = 1897 units

£880 is divided between Jim, Krutika &amp; Natasha so that Jim gets twice as much as Krutika, and Krutika gets three times as mu
krok68 [10]

Answer:

264 pounds

Step-by-step explanation:

Write the question in the form of a ratio:

Natasha: Krutika: Jim

1:3:6

Now, we divide the amount of 880 in the ratio.

there are 10 parts in total.

1 part = 880 divided by 10 = 88.

since Krutika gets 3 parts, she gets 88 x 3 = 264

Given the parent function
yanalaym [24]

Answer:

Option a is right.

Step-by-step explanation:

Parent funciton is

f(x) = x^3

The new graph is

f(x) = -2x^3

Since there is no change for x, there is no horizontal shift.

BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.

Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2

Option a is right

i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.
