As per the given **height **of the wall, the approximate weight is **149kN**

The term Hydrostatic refers to the force exerted by **static **water on the plate or object and its **magnitude **depends upon the positioning of the object inside the water.

Here we have given the following values,

Height = 2.76 upright

Width = 10 m

Here we have to consider the hydrostatic **force **acting on the wall about the pinned point say P then the **expression **is looks like,

=> F = ωAx

=> F = 9810(10 × 4) × 2

=> F = 784800 N = 785KN

Now, the weight is calculated as per the **Hydrostatic **method as,

=> W = (1.33/7) x 785

=> W = 149 kN

The parent function of a quadratic equation is vertically stretched by a factor of 2, then translated 4 units left and one unit down

**Answer:**

[tex]f"'(x) = 2(x-4)^2 - 1[/tex]

**Step-by-step explanation:**

**Given**

[tex]f(x) = x^2[/tex] --- the quadratic function

Vertically stretched by 2

Translation: [tex]4\ units[/tex] left and [tex]1\ unit[/tex] down

**Required**

Determine the new function

[tex]f(x) = x^2[/tex]

**The rule for vertical stretch is:**

[tex](x,y) \to (x,ay)[/tex]

**In this case:**

[tex]a = 2[/tex]

**So, we have:**

[tex]f(x) = x^2[/tex]

[tex]f'(x) = a * f(x)[/tex]

[tex]f'(x) = a * x^2[/tex]

**Substitute: **[tex]a = 2[/tex]

[tex]f'(x) = 2 * x^2[/tex]

[tex]f'(x) =2x^2[/tex]

**Translation: 4 units left **

The rule is:

[tex](x,y) \to (x - c,y)[/tex]

**In this case: **[tex]c =4[/tex]

**So, we have:**

[tex]f"(x) = 2(x - 4)^2[/tex]

**Translation: 1 unit down**

The rule is:

[tex](x,y) \to (x,y-d)[/tex]

In this case, [tex]d=1[/tex]

**So, we have:**

[tex]f"'(x) = f"(x) - 1[/tex]

[tex]f"'(x) = 2(x-4)^2 - 1[/tex]

consider the function below

f(x) = x^2 - 6x + 5

HURRY AND NO LINKS

Answer:

The value of the angle is 60 degrees

Step-by-step explanation:

Here, we want to find the value of the angle marked 2

From the question, we can see that we have three marked interior angles

These are the angles 1, 2 and 3

Mathematically, the interior angles of an equilateral triangle are equal

This means that each of the interior angle of an equilateral triangle measures 60 degrees

Hence, this means that the value of the angle marked 2 is 60 degrees

find 5 rational number between 2/-7 and 5/6

Answer:

-11/42, -10/42, 10/42, 11/42, 12/42

Step-by-step explanation:

First of let's find the LCM of the denominators.

LCM of 6 and 7 is 42

Thus, -2/7 can also be expressed in terms of 42 as denominator as; -12/42

Similarly, 5/6 can also be expressed in terms of 42 as denominator as; 35/42

Thus, any five rational numbers could come in the form of the numerator being between -12 to 35 with the denominator being 42.

Thus, five rational numbers between -2/7 and 5/6 are;

-11/42, -10/42, 10/42, 11/42, 12/42

A small car has a tire with a 13-inch diameter. A truck has a tire with a 29-inch diameter. How much farther than the car does the truck have to drive for its tire to complete one revolution?

**Answer:**

50.27in

**Step-by-step explanation:**

Given data

Diameter of small tire= 13in

Radius= 13/2= 6.5in

Circumference= 2πr

C= 2*3.142*6.5

C= 40.85 in

Diameter of Big tire= 29in

Radius= 29/2= 14.5in

Circumference= 2πr

C= 2*3.142*14.5

C= 91.118in

Hence the difference in distance between the two tires after on revolution is

=91.118-40.85

=50.27in

**Answer:**

p(x - 4) = x³ - 12x² + 48x - 69

**Step-by-step explanation:**

To evaluate p(x - 4), substitute a = x - 4 into p(a), that is

p(x - 4) = (x - 4)³ - 5

= (x - 4)(x - 4)(x - 4) - 5 ← expand 2nd/ 3rd factors using FOIL

= (x - 4)(x² - 8x + 16) - 5 ← distribute parenthesis

= x³ - 8x² + 16x - 4x² + 32x - 64 - 5 ← collect like terms

= x³ - 12x² + 48x - 69

Researchers investigated the influence of environmental pH on the activity of peroxidase, an enzyme that catalyzes the conversion of hydrogen peroxide to water and oxygen gas. In an experiment, the researchers added a hydrogen peroxide solution containing guaiacol to several identical test tubes and adjusted the solution in each test tube to a different pH . The researchers included the guaiacol because it caused the solutions to change color as the reactions proceeded, which the researchers relied on for measuring reaction rates. Finally, the researchers added the same amount of peroxidase to each test tube and measured the rate of each reaction at 23C . The results of the experiment are represented in Figure 1.Based on Figure 1, which of the following statements best predicts the effect that a change from a moderately acidic environment ( pH near 6) to a basic environment will have on peroxidase activity?O Peroxidase activity will decrease.O Peroxidase activity will increase.O Peroxidase activity will stay the same.O Peroxidase activity will increase at first and then decrease.
