The sum of 9 times a number and 7 is 6
Given statement solution is :- The value of the number is -1/9.
Let's solve the problem step by step.
Let's assume the number we're looking for is represented by the variable "x".
The problem states that the sum of 9 times the number (9x) and 7 is equal to 6. We can write this as an equation:
9x + 7 = 6
To isolate the variable "x," we need to move the constant term (7) to the other side of the equation. We can do this by subtracting 7 from both sides:
9x + 7 - 7 = 6 - 7
This simplifies to:
9x = -1
Finally, to solve for "x," we divide both sides of the equation by 9:
9x/9 = -1/9
This simplifies to:
x = -1/9
So, the value of the number is -1/9.

Cara is standing on the edge of a 15 foot high diving board. Her friend Sierra is Treading Water 45 feet from the spot in the pool directly below Cara. What is the angle of depression from the edge of the diving board to the surface of the water where Sierra is located?
Using the information given in the exercise, you can draw the following diagram:
Where β is the angle of depression (in degrees) from the edge of the diving board to the surface of the water where Sierra is located.
In order to find the measure of the angle of depression, you need to use the following Inverse trigonometric function:
\(\beta=arc\tan (\frac{opposite}{adjacent})\)In this case, you can identify that:
\(\begin{gathered} opposite=15 \\ adjacent=45 \end{gathered}\)Therefore, substituting the values, you get the following result:
\(\begin{gathered} \beta=arc\tan (\frac{15}{45}) \\ \\ \beta=18.43\degree \end{gathered}\)The answer is:

Form the given five quadratics , the one representing the repeated roots is equal to option d. 25x² - 30x + 9 and repeated roots are 3/5 or 3/5.
Quadratics representing repeated roots has discriminant equals to zero.
Standard quadratic equation is:
ax² + bx + c = 0
Discriminant 'D' = b² - 4ac
option a. -x²+ 18x + 81
Discriminant
'D' = 18² - 4(-1)(81)
= 324 + 324
= 648
D>0 has distinct roots.
option b. 3x²- 3x - 168
Discriminant
'D' = (-3)² - 4(-3)(-168)
= 9 - 2016
= -2007
D< 0 has distinct roots.
option c. x²- 4x - 4
Discriminant
'D' = (-4)² - 4(1)(-4)
= 16 + 16
= 32
D>0 has distinct roots.
option d. 25x²- 30x + 9
Discriminant
'D' = (-30)² - 4(25)(9)
= 900 - 900
= 0
D = 0 has repeated roots.
Repeated roots are:
x = ( -b ±√D ) / 2a
= [-(-30)±√0 ]/ 2(25)
= 30/ 50
= 3/5.
option e. x² - 14x + 24
Discriminant
'D' = (-14)² - 4(1)(24)
= 196 - 96
= 100
D>0 has distinct roots.
Therefore, the quadratics which represents the repeated roots are given by option d. 25x² - 30x + 9 and its repeated roots are 3/5 or 3/5.

The process of age hardening involves: Time Tent 0.3 Select one: heating the alloy to a temperature in the single phase field, followed by quenching, then reheating to an intermediate temperature heating the alloy to a temperature within the two phase field, followed by quenching, then reheating to an intermediate temperature slowly cooling the alloy from the liquid phase field heating the alloy to a temperature in the single phase field, followed by slow cooling heating the alloy to a temperature in the two phase field, followed by slow cooling
The process of age hardening, also known as precipitation hardening, is a heat treatment technique used to increase the strength and hardness of certain alloys, such as aluminum, copper, and some steels. It involves a series of steps to achieve the desired properties.
The correct process for age hardening involves heating the alloy to a temperature in the single phase field, which allows for the dissolution of alloying elements into the solid solution. This is followed by a rapid quenching process, which freezes the alloy's microstructure and prevents the formation of precipitates. The next step is reheating the alloy to an intermediate temperature, below the melting point, but within the two-phase field. This temperature is carefully chosen to allow the formation and growth of fine precipitates throughout the material. These precipitates act as obstacles to the movement of dislocations, resulting in increased strength and hardness.
The key aspect of the age hardening process is the controlled precipitation of fine particles, which are responsible for the strengthening effect. The choice of temperature and time during the heat treatment is critical to achieving the desired properties. By carefully controlling the heating, quenching, and reheating steps, engineers can tailor the material's mechanical properties to meet specific requirements for different applications.
Overall, age hardening is a valuable process that enhances the performance of alloys by adjusting their microstructure through controlled precipitation, ultimately improving their strength and hardness.

the daily high temperature for chattanooga is normally distributed with mean 79 and standard deviation 4. find the probability that a randomly chosen temperature is between 70 and 75.
The probability of randomly selecting a temperature between 70 and 75 is approximately 0.8291.
To find the probability that a randomly chosen temperature is between 70 and 75, we need to use the z-score formula as shown below:
z = (x - μ) / σ
Where:x = 70 and 75μ = 79σ = 4z1 = (70 - 79) / 4 = -2.25z2 = (75 - 79) / 4 = -1P(70 < x < 75) = P(-2.25 < z < -1)
To find the probability for the above inequality, we need to use a calculator. We know that the probability of the standard normal distribution is equal to 1.
Hence, P(-2.25 < z < -1) = Φ(-1) - Φ(-2.25) = 0.8413 - 0.0122 ≈ 0.8291. Therefore, the probability is about 0.8291.

The perimeter of the base of a right square pyramid is 24 cm. The height of the pyramid is 6 cm. What is the volume of the pyramid? 48 cm3 72 cm3 32 cm3 60 cm3
Answer:
72cm
Step-by-step explanation:
The volume of the base of a right square pyramid is 72 cubic centimeters, the option second is correct.
It is given that the perimeter of the base of a right square pyramid is 24 cm and the height of the pyramid is 6 cm.
It is required to find the volume of the right square pyramid.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We know the formula for finding the volume (V) of a right square pyramid is:
\(\rm V= a^2\times\frac{h}{3}\) Where a is the base side and h is the height of the right square pyramid.
\(\rm The \ perimeter \ of \ the \ base \ of \ a \right \ square \ pyramid = 4\times(side)\)
\(\rm 24 = 4a\\\rm a=6 \ cm\)
And h = 6 cm, putting this value in the above volume formula, wet get:
\(\rm V= (6)^2\times\frac{6}{3} \\\rm V= 36\times 2\\\rm V=72 \ cm^3\)
Thus, the volume of the base of a right square pyramid is 72 cubic centimeters, the option second is correct.
