For integer values of a and b, b^a = 8. The ratio of a to b is equivalent to the ratio of c to d, where c and d are integers. What is the value of c when d = 10?
Answers
3:2 = c:10
c is then equal to 10/2 *3
15
To find the value of c when d = 10, we first need to determine the values of a and b. Given that b^a = 8, we know that 8 is the result of raising b to the power of a.
Since the question states that a and b are integers, there are a limited number of possibilities to consider. Let's examine the possible combinations of a and b that satisfy this equation: [tex]1^3 = 1 2^3 = 8 3^2 = 9[/tex](which is not 8) [tex]4^2 = 16[/tex] (which is not 8) [tex]5^1 = 5 6^1 = 6 7^1 = 7 8^1 = 8[/tex]From these calculations, we find that the only combination that satisfies the equation is a = 3 and b = 2. Now, let's consider the ratio of a to b and the ratio of c to d.
The ratio of a to b is a/b = 3/2. The question states that the ratio of a to b is equivalent to the ratio of c to d, which means: a/b = c/d Given that d = 10, we can substitute the value into the equation: [tex]3/2 = c/10[/tex] Next, we can cross-multiply to solve for c: [tex]3 * 10 = 2 * c 30 = 2[/tex] c Dividing both sides by 2, we get: c = 15 Therefore, when d = 10, the value of c is 15. In conclusion, when d = 10, the value of c is 15 based on the given equation and calculations.

To descend fastest from the point (5,4) on the surface z=15-(2x^2+3y^2), you should walk in the direction of the negative gradient vector, normalized to be a unit vector, which is approximately <0.640, 0.768>.
Explanation:To determine the direction in which you should walk to descend fastest from the point (5,4) on the surface z=15-(2x^2+3y^2), we can find the gradient of the surface at that point. The gradient vector will point in the direction of the steepest ascent, so the direction of the steepest descent is the opposite direction of the gradient vector.
First, calculate the partial derivatives of z with respect to x and y:
∂z/∂x = -4x
∂z/∂y = -6y
Next, evaluate these derivatives at the point (5,4):
∂z/∂x(5,4) = -4(5) = -20
∂z/∂y(5,4) = -6(4) = -24
The gradient vector at (5,4) is <-20, -24>. To get the direction of steepest descent, we take the negative of the gradient vector, which is <20, 24>.
Finally, normalize this vector to make it a unit vector (so it has a length of 1):
Length of gradient vector = √(20^2 + 24^2) = √(400 + 576) = √976 ≈ 31.24
The unit vector in the direction of steepest descent is <20/31.24, 24/31.24> ≈ <0.640, 0.768>.

Is m=0.75d-2 proportional?
Answers
If m = 0.75d, then ratio m/d = (0.75d)/d = 0.75
In this example, the ratio is (.75d-2)/d = 0.75 - (2/d).
Therefore, it is not proportional.
Answer:
No, the equation m=0.75d-2 does not represent proportional relationship.
Step-by-step explanation:
The given equation is
[tex]m=0.75d-2[/tex]
We need to check whether the given equation represents proportional relationship or not.
If variable y is proportional to variable x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is the constant of proportionality.
At x=0 the value of y is 0. It means, if a linear equation represents proportional relationship then it must be passes though the origin.
Substitute d=0 in the given equation.
[tex]m=0.75(0)-2[/tex]
[tex]m=-2[/tex]
The line passes through the point (0,-2).
Since the line does not pass through the origin, therefore it does not represent proportional relationship.

What does −2/3(12c−9)+14c simplify to?
Answers
Answer:
The simplified form of the provided expression is [tex]6c+6[/tex] or [tex]6(c+1)[/tex]
Step-by-step explanation:
Consider the provided expression.
[tex]\frac{-2}{3}(12c-9)+14c[/tex]
Use the distributive property:
[tex]a(b+c)=ab+ac[/tex]
By using the above property we can simplify it as shown:
[tex]\frac{-2}{3}\times 12c-\frac{-2}{3}\times 9+14c[/tex]
[tex]-2\times 4c+2\times 3+14c[/tex]
[tex]-8c+6+14c[/tex]
Add or subtract the like terms.
[tex]6c+6[/tex] or [tex]6(c+1)[/tex]
Thus, the simplified form of the provided expression is [tex]6c+6[/tex] or [tex]6(c+1)[/tex]
The simplest form of expression by applying distributive property would be, 6 (c + 1)
Given that,
The expression is,
[tex]\dfrac{- 2}{3} (12c - 9) + 14c[/tex]
Now, used the concept of distributive property to simplify the expression,
[tex]\dfrac{- 2}{3} (12c - 9) + 14c[/tex]
Apply distributive property,
[tex][\dfrac{- 2}{3} \times 12c - (\dfrac{- 2}{3} )\times 9] + 14c[/tex]
[tex][- 2 \times 4c + 2 \times 3] + 14c[/tex]
[tex][- 8c + 6] + 14c[/tex]
Combine like terms,
[tex]- 8c + 14c + 6[/tex]
[tex]6c + 6[/tex]
Take 6 as a common term,
[tex]6 (c + 1)[/tex]
So, the solution of expression 6 (c + 1).
