Answer:

7:4

Step-by-step explanation:

The number of sharks at the aquarium is 840

The number of lion fish is 630

The total number of fish is 1470

Therefore the ratio of fish to sharks can be calculated as follows

= 1470/840

= 7:4

Hence the ratio of fish to sharks is 7:4

The differential dy when x = 5 and dx = 0.1 is 0.03/√5.

Given the equation: y = 3√x  ----(1)

Now we have to find the change in y, ∇y when x = 5 and ∇x = 0.1.

To find out the change in y, we will differentiate the given equation with respect to x.

Here,∴ y = 3x^(1/2)We know that ∇y = dy/dx …(2)

Again, y = 3x^(1/2)By differentiating with respect to x, we get, dy/dx = 3/2 × x^(-1/2)

Therefore, when x = 5,∴ ∇y = dy/dx = 3/2 × 5^(-1/2)

= 3/2 × 1/√5 = 3/2√5

Answer: ∇y = 3/2√5 which is approximately equal to 0.67 We are given y = 3√x and are to find the differential dy when x = 5 and dx = 0.1.

In order to find the differential dy, we first need to calculate its value for a particular value of x. Here, the value of x is given as 5.

Therefore, the differential dy is given by:dy = (dy/dx) * dx ... (1)

Now, we need to calculate dy/dx. We know that: y = 3√xDifferentiating both sides with respect to x, we get: dy/dx = (3/2) * (x^(-1/2))... (2)

Substituting the value of x = 5 in equation (2), we get: dy/dx = (3/2) * (5^(-1/2))

= (3/2) * (1/√5)

Now, substituting the values of dy/dx and dx in equation (1), we get: dy = (3/2) * (1/√5) * 0.1

= 0.03/√5

Hence, the differential dy when x = 5 and dx = 0.1 is 0.03/√5.

Step-by-step explanation:

He has to be at work by 10:30, but it takes 20 mins to walk

So, 10:30-20 minutes=10:10

We then look at the arrival time closest to this, which would mean he would arrive at 10.06.

trace this back the bus would gett him at 8:38, but its a 5min walk.

8:38-5 minutes+8.33

By linear search, We discovered that element 9 is the seventh in the sequence, meaning that number 9 appears on the list in the sequence 1, 3, 4, 5, 6, 8, 9, 11.

A grouping of numbers in a specific order is known as a sequence. On the other hand, a series is described as the accumulation of a sequence's constituent parts.

Given,

Sequence = 1, 3, 4, 5, 6, 8, 9, 11

By linear search,

The first element is compared to 9 first. If the element's value is less than nine, we compare the subsequent element with nine, and so on.

Step 1: 9 is not the same as 1.

Step 2: 9 is not the same as 3.

Step 3: 9 is not the same as 4

Step 4: 9 is not the same as 5

Step 5: 9 is not the same as 6

Step 6: 8 and 9 are not the same.

Step 7: 9 equals 9.

We discovered that element 9 is the seventh in the sequence, meaning that number 9 appears on the list.

Average rate of change of \(y = x^2 + 4x - 1\\\) over the interval \(-4 \leq x \leq 1\)  is 1

What is average rate of change of a curve?

Average rate of change of a curve is equal to the slope of the curve and is obtained by dividing the change in functional value by the change in the value of the domain.

Here,

\(y = x^2 + 4x - 1\\\)

At x = -4,

\(y = (-4)^2+ 4(-4)-1\\y = -1\)

At x = 1

\(y = (1)^2 + 4(1) -1\\y = 4\)

Average rate of change of \(y = x^2 + 4x - 1\\\) over the interval \(-4 \leq x \leq 1\)

= \(\frac{4 - (-1)}{1- (-4)}\\\\\\\frac{5}{5}\\\\1\)

SA = 696cm^2

Step-by-step explanation:

First we need to identify the shapes

There are 3 rectangles and 2 triangles

Now the individual surface area for each shape

20 x 10 = 200 (1 rectangle)

1/2(12 x 8) = 48 (1 triangle)

Now we add them together

(200 x 3) + (48 x 2) = 696
