Answer:
The slope of the line is [tex]\frac{-1}{2}[/tex]
Step-by-step explanation:
The rule of the slope of a line is
m = [tex]\frac{y2-y1}{x2-x1}[/tex] (x1, y1) and (x2, y2) are two points lie on the line→ Let us solve the question
∵ The line contains the points B (-4, 4) and R (0, 2)
∴ x1 = -4 and y1 = 4
∴ x2 = 0 and y2 = 2
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{2-4}{0--4}=\frac{-2}{4}=\frac{-1}{2}[/tex]
∴ m = [tex]\frac{-1}{2}[/tex]
∴ The slope of the line is [tex]\frac{-1}{2}[/tex] .

Step-by-step explanation:
Quadratic Formula: [tex]x = \frac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]
√-1 is imaginary number i
Step 1: Define Quadratic
8a² + 6a + 5 = 0
a = 8
b = 6
c = 5
Step 2: Plug into Quadratic Formula
[tex]x = \frac{-6 \pm \sqrt{6^2-4(8)(5)} }{2(8)}[/tex]
Step 3: Solve
[tex]x = \frac{-6 \pm \sqrt{36-160} }{16}[/tex]
[tex]x = \frac{-6 \pm \sqrt{-124} }{16}[/tex]
[tex]x = \frac{-6 \pm \sqrt{124} (\sqrt{-1} )}{16}[/tex]
[tex]x = \frac{-6 \pm i\sqrt{124}}{16}[/tex]
[tex]x = \frac{-6 \pm 2i\sqrt{31}}{16}[/tex]

which equation in a standar form has a grpah that passes through the point (-4,2) and has a slope 9/2
Answers
Equation in standard form that has a graph that passes through point (-4, 2) and has slope of 9/2 is calculated to be as equal to -40.
The equation in standard form that has a graph that passes through the point (-4, 2) and has a slope of 9/2 is given by :
Step 1: Recall the standard form of a linear equation
The standard form of a linear equation is Ax + By = C, where A, B, and C are constants.
Step 2: Substitute given values
The equation should pass through the point (-4, 2) and should have a slope of 9/2.
Therefore, the slope-intercept form of the equation is given by:
y - 2 = (9/2)(x + 4)
Multiplying through by 2, we have: 2y - 4 = 9(x + 4)2y - 4
= 9x + 36
Rearranging, we get: 9x - 2y
= -40
Therefore, the equation in standard form that has a graph that passes through the point (-4, 2) and has a slope of 9/2 is 9x - 2y
= -40.

water runs into a conical tank at the rate of 26 cubic inches per second. the tank stands point down and has a height of 11 inches and a base radius of 7 inches. how fast is the water level rising when the water is 5 inches deep?
Answers
The water level is rising at a rate of approximately 0.017 inches per second when the water is 5 inches deep.
Let's start with the formula for the volume of a cone.V= 1/3πr²h
Here, h is the height of the water level at a given time. We are given that water is flowing in at a rate of 26 cubic inches per second. Therefore, we can calculate the rate of change of volume as dV/dt = 26.The tank stands point down, which means that the apex of the cone is at the bottom and the base is at the top. The height of the tank is 11 inches, so when the water level is 5 inches deep, the remaining height of the tank that is empty is 11 - 5 = 6 inches.The radius of the tank at the base is 7 inches, which means that the radius of the top of the water level is proportional to the height of the water level. Therefore, the radius of the top of the water level when the water level is 5 inches deep is: r = (5/11) x 7 = 3.18 inches.Now we can use the formula for the volume of a cone to find the volume of water in the tank when the water level is 5 inches deep.
V= 1/3πr²h= 1/3 x π x (3.18)² x 5= 53.4 cubic inches
Now we can find the rate of change of height with respect to time using the formula
dV/dt = A dh/dt, where A is the area of the base of the tank.
A = πr² = π(7)² = 49π square inches.
Therefore, we have:
26 = 49π dh/dt
dh/dt = 26 / (49π)
dh/dt ≈ 0.017
The water level is rising at a rate of approximately 0.017 inches per second when the water is 5 inches deep.

Find the value of the discriminant. Then describe the number and type of roots for the equation. 3x^2\:+\:4x\:-7=0
Answers
The given equation has two real and distinct roots.
The formula for the discriminant is b² - 4ac. For the given equation, 3x² + 4x - 7 = 0,
the value of a = 3, b = 4 and c = -7.Substituting these values in the formula for discriminant, we get:$$\begin{aligned}b^2-4ac&=4^2-4\times3\times(-7) \\&=16+84 \\&=100 \end{aligned}$$
Hence, the value of discriminant is 100.Using the value of the discriminant, we can determine the nature of roots. If the discriminant is positive, then the roots are real and distinct.
If the discriminant is zero, then the roots are real and equal.
If the discriminant is negative, then the roots are imaginary and conjugate.In this case, the discriminant is positive (100), so the roots will be real and distinct.

Use the remainder Theorem to find the remainder for (x2- 2)/(x - 1) and state whether or not the binomial is a factor of
the polynomial.
Answers
Answer:
The remainder is -1
The binomial is not a factor of the polynomial
Step-by-step explanation:
In the algebraic division, there are 4 terms
Dividend ⇒ the term before the division signDivisor ⇒ the term after the division signQuotient ⇒ the answerRemainder ⇒ appear when the dividend not divisible by the divisor (the divisor is not a factor of the dividend)The remainder theorem:
If you divide a polynomial f(x) by (x - h), then the remainder is f(h).You do not need to use the long division to find the remainder, just evaluate the polynomial when x = h to find the remainder.If h(h) = 0, then (x - h) is a factor of f(x)Let us use it to solve the question
∵ The dividend is x² - 2
∴ f(x) = x² - 2
∵ The divisor is x - 1
∴ (x - h) = (x - 1)
∴ h = 1
Let us find f(1)
∵ f(1) = (1)² - 2 = 1 - 2 = -1
∴ f(1) = -1
∴ The remainder is -1
∵ f(1) ≠ 0
∴ x - 1 is not a factor of x² - 2
∴ The binomial is not a factor of the polynomial
A uniform distribution is defined over the interval from 2 to 5.
What is the range of the random variable, x?
Over the range, what is the probability of the random variable, x?
What is the area of this uniform distribution?
Answers
The probability of x within this range is constant and equal to 1/3. The area under the uniform distribution curve is 1.
The range of the random variable, x, in a uniform distribution from 2 to 5 is [2, 5]. It represents the entire interval of possible values for x.
The probability of the random variable, x, in a uniform distribution is constant over the range. Since it is a uniform distribution, the probability density function is equal for all values within the range. Therefore, the probability of x taking any specific value within the range [2, 5] is the same, and it is given by 1 divided by the length of the range:
Probability of x = 1 / (length of range)
= [tex]P(x) = \frac{1}{5 - 2} = \frac{1}{3}[/tex]
The area of the uniform distribution is represented by the probability density function over the range. Since it is a uniform distribution, the probability density is constant within the range. Therefore, the area under the curve is equal to the length of the range multiplied by the constant probability density:
Area = (length of range) * (probability density) = (5 - 2) * (1 / (5 - 2)) = 3 * (1 / 3) = 1.
Hence, the area of the uniform distribution is 1.
