Which calculation can be used to find the value of p in the equation p³= 8?
Op=√8
Op=3•√8
Op=2•√8
Op=√8
Answer:
Option 1 ========> p = ∛8
Step-by-step explanation:
In order to make p the subject we would need to cube root both sides and would therefore get :
∛(p³) = ∛8
p = ∛8
Just a side not but you wrote the first option wrong but it's fine as you attached an image.
Hope this helped and have a good day
The calculation p=∛8 can be used to find the value of p in the equation p³= 8
What is Expression?An expression is combination of variables, numbers and operators.
The given equation is p³= 8
p to the power of three equal to eight
p is the variable in the given equation
We have to find the value of p from the equation
Take cube root on both the side
∛ p³= ∛8
On left hand side the cube will be cancelled and left with p
p=∛8
Hence, p=∛8 calculation can be used to find the value of p in the equation p³= 8

Answer:
x<-4 or x≤4
Step-by-step explanation:
The solution of the inequality is x > -4 and x ≤ 4.
So, the graph B is correct.
Given is an inequality, x+7 > 3 and x-5 ≤ -1, we need to solve and identify the graph,
To solve the compound inequality, let's solve each inequality separately and then find the intersection of the solutions.
Inequality 1: x + 7 > 3
Subtract 7 from both sides:
x > 3 - 7
x > -4
Inequality 2: x - 5 ≤ -1
Add 5 to both sides:
x ≤ -1 + 5
x ≤ 4
Now, we need to find the intersection of the solutions for both inequalities.
Since the conjunction between the two inequalities is "and," we need to find the common solution.
The common solution is the values of x that satisfy both x > -4 and x ≤ 4. From the two inequalities, we can see that the common solution range is from -4 to 4, including -4 but not including 4.
Therefore, the solution to the compound inequality is: -4 < x ≤ 4

Complete the slope-intercept form of the linear equation that represents the relationship in the table
Answer:
y = 3x - 4
Step-by-step explanation:
The general structure of a line in slope-intercept form is:
y = mx + b
In this form, "m" is the slope and "b" is the y-intercept.
(Step 1)
Before you can determine this equation, you need to find the value of "m". Since you were given the value of two points, you can find this by using the point-slope form. The general structure of the point-slope equation is:
y₁ - y₂ = m(x₁ - x₂)
y₁ - y₂ = m(x₁ - x₂) <---- Point-slope equation
-1 - 8 = m(1 - 4) <---- Insert "x" and "y" values from table
-9 = m(1-4) <---- Simplify left side
-9 = -3m <---- Simplify inside parentheses
3 = m <---- Divide both sides by -3
(Step 2)
Now that you know "m", you can plug it and the "x" and "y" values of one point into the slope-intercept equation to find the value of "b".
y = mx + b <---- Slope-intercept equation
y = 3x + b <---- Plug 3 into "m"
-1 = 3(1) + b <---- Plug "x" and "y" values in
-1 = 3 + b <---- Multiply 3 and 1
-4 = b <---- Subtract 3 from both sides
(Step 3)
Now that you know that m = 3 and b = -4, you can substitute these values into the slope-intercept form to find your final answer. You can check your answer by plugging the "x" values from the table into the equation to verify that you get the correct "y" values.
y = 3x - 4

Step-by-step explanation:
once the level of medicine reaches a value, where 30% are 23mL (so, whatever is lost, is immediately replaced again), that is then the long run value for the amount of the drug in the patient's body.
so,
30% = 23 mL
1% = 30%/30 = 23/30 = 0.766666666...
100% = 1%×100 = 0.766666666... × 100 = 76.666666...
so, once the level reaches 76.666666... mL in the body, it will remain constant, as the daily filtered out 30% are 23 mL, and the daily add-on is also 23 mL.
so, the answer is
76.667 mL
Boubacar has a deck that measures 3 feet by 14 feet. He wants to increase each
dimension by equal lengths so that its area is tripled. By how much should he
increase each dimension?
Answer:
4
Step-by-step explanation:
(3 × 14) × 3 = 126
7 × 18 = 126
Boubacar will have to increase each dimension by 4 ft so that its area is triple.
What is the area of a rectangle?
The area of a rectangle is given by -
A[R] = L x B
where -
L is Length of rectangle
B is Breadth or width of rectangle.
Given is a deck that measures 3 feet by 14 feet. Boubacar wants to increase each dimension by equal lengths so that its area is tripled.
Assume that he increases the dimensions by x ft.
Initial Area = [A] = 3 x 14 = 42 ft².
Final Area = [A'] = 3[A] = 3 x 42 = 126 ft²
Initial dimensions = (L x B) = 3 feet x 14 feet
Final dimensions = (L' x B') = (3 + x) × (14 + x)
Now -
(L' x B') = 126
(3 + x)(14 + x) = 126
3(14 + x) + x(14 + x) = 126
42 + 3x + 14x + x² = 126
x² + 17x - 84 = 0
Solving the equation, we get -
x = 4 [ non negative number ]
Therefore, Boubacar will have to increase each dimension by 4 ft so that its area is tripled.

5x + 2 = 2x + 6
C.
4(x + 5) + 2 = 6x + 4(x + 2)
D.
4x + 5 = 2
The equation that has infinitely many solutions is A. 4x + 5(2x + 6) = 14x + 30
How to determine the equation?An equation with infinitely many solutions is represented as:
ax + b = ax + b
This means that both sides of the equation must be the same.
Next, we test the options:
4x + 5(2x + 6) = 14x + 30
Open the bracket
4x + 10x + 30 = 14x + 30
Evaluate the like terms
14x + 30 = 14x + 30
Both sides of the equation must be the same.

In general, they're not similar.
In any triangle with side lengths a, b, and c, we have the aptly-named triangle inequality that says the largest side is no larger than the sum of the smaller sides. In other words, if a and b are both smaller than c, then
a + b ≥ c
Suppose x < 12. Then BC corresponds to either YZ or XY.
• If BC corresponds to YZ, then the triangles are similar if and only if
BC/YZ = AB/XY = AC/XZ
x/2 = 9/3 = 12/4 = 3 ⇒ x = 6
• If BC corresponds to XY, then triangle similarity means
BC/XY = AB/YZ = AC/XZ
x/3 = 9/2 = 12/4
but this fails because 9/2 ≠ 12/4 = 3.
Suppose x > 12. Then BC corresponds to XZ, and
x/4 = 12/3 = 9/2
but this also fails because 12/3 = 4 ≠ 9/2.
(We ignore the case of x = 12 because that would make ∆ABC isosceles, and ∆XYZ certainly is not.)
So ∆ABC and ∆XYZ are similar only if x = 6. Under this condition, similarity would follow from the SSS similarity theorem.

Find the gradient of the curve y =2x³-7x+4when x=-2
By applying concepts from vectorial calculus, we conclude that the gradient of the one variable function y = 2 · x³ - 7 · x + 4 when x = -2 is equal to 17.
How to find the gradient of a functionA gradient is a generalization of the tangent curve used for multivariate function, that is, a function with more than one variable. In this case we have a function with one variable, which means that the gradient is equal to the slope:
[tex]\nabla f = \frac{df}{dx}[/tex] (1)
Now we proceed to calculate the gradient of the curve:
[tex]\nabla f = 6\cdot x^{2}-7[/tex]
[tex]\nabla f = 6\cdot (-2)^{2}-7[/tex]
[tex]\nabla f = 17[/tex]
By applying concepts from vectorial calculus, we conclude that the gradient of the one variable function y = 2 · x³ - 7 · x + 4 when x = -2 is equal to 17.
