7(6)^×=39How do I solve for x?
Answers
Given:
\(7(6)^x=39\)Required:
We need to find the value of x.
Explanation:
Divide both sides of the equation by 7.
\(\frac{7(6)^x}{7}=\frac{39}{7}\)\((6)^x=\frac{39}{7}\)Take a natural log on both sides of the equation.
\(In(6)^x=In(\frac{39}{7})\)\(Use\text{ }In(a)^n=nIn(a).\)\(xIn(6)=In(\frac{39}{7})\)\(Divide\text{ both sides of the equation by }In(6).\)\(\frac{xIn(6)}{In(6)}=\frac{In(39\/7)}{In(6)}\)\(x=\frac{In(39\/7)}{In(6)}\)\(x=0.9587\)\(x=0.96\)Final answer:

A regression model is used to show the relationship between variables on a scatter plot
The regression equation is: \(\^y = 28.2\^x- 27.9\)The likely blood pressure for a patient with sodium intake of 6.0 and 8.5 are 141.3 and 211.8, respectivelyHow to formulate the regression equationUsing the Microsoft Office Excel, we have the following calculation summary
Sum of X = 84Sum of Y = 2030Mean X = 7Mean Y = 169.1667Sum of squares (SSX) = 2.82Sum of products (SP) = 79.4So, the regression equation is:
\(\^y = 28.2\^x- 27.9\)
Blood pressure for a sodium intake of 6.0 and 8.5This means that x = 6.0 and x = 8.5
When x = 6.0, we have:
\(\^y = 28.2 * 6.0- 27.9\)
\(\^y = 141.3\)
When x = 8.5, we have:
\(\^y = 28.2 * 8.5- 27.9\)
\(\^y = 211.8\)
Hence, the likely blood pressure for a patient with sodium intake of 6.0 and 8.5 are 141.3 and 211.8, respectively

This problem refers to triangle ABC. If B = 150°, C = 20°, and c = 21 inches, find b. (Round your answer to the nearest whole number.)
b = ? in
Answers
Answer:
Step-by-step explanation:
To solve for b, we can use the law of sines, which states that in any triangle ABC:
a/sin(A) = b/sin(B) = c/sin(C)
Here, we are given B = 150°, C = 20°, and c = 21 inches. We can solve for the remaining angle A by using the fact that the angles of a triangle add up to 180°:
A + B + C = 180°
A = 180° - B - C
A = 180° - 150° - 20°
A = 10°
Now we can use the law of sines to solve for b:
a/sin(A) = b/sin(B)
a = c * sin(A)/sin(C) = 21 * sin(10°)/sin(20°)
b = a * sin(B)/sin(A) = 21 * sin(10°)/sin(20°) * sin(150°)/sin(10°)
b = 21 * sin(150°)/sin(20°)
Using a calculator, we get:
b ≈ 41 inches (rounded to the nearest whole number)
Therefore, the length of side b is approximately 41 inches.

7.745966… > √59
7.745966… < √59
Answers
The inequality statement 7.745966… < √59 is true.
The symbol √59 represents the square root of 59, which is approximately 7.681146. The value 7.745966… is a decimal representation of the square root of 59 that has been rounded to three decimal places. Because 7.681146 is less than 7.745966, the inequality statement 7.745966… < √59 is true.

\(undefined\)angle of is a right angle. the sides of are the diameters of semicircles as shown. the area of the semicircle on equals , and the arc of the semicircle on has length . what is the radius of the semicircle on ?
Answers
The radius of the semicircle having an arc of length equal to 8.5 \(\pi\) in a right-angle triangle ABC is equal to 7.5 cm.
Given:
Angle ABC of triangle ABC is a right angle. The sides of ABC are the diameters of semicircles.
The area of the semicircle on AB equals 8\(\pi\).
Area of a semicircle = \(\pi r^2/2\)
Therefore:
\(\pi r^2/2\) = 8\(\pi\)
\(r^2 = 16\)
\(r = 4\)
Next, the arc of the semicircle on AC has a length of 8.5\(\pi\).
Length of the arc of a semicircle = \(\pi r\)
\(\pi r\) = 8.5\(\pi\)
\(r = 8.5\)
Using Pythagoras theorem
\(8.5^{2} = 4^{2} + x^{2}\)
\(x^{2} = 8.5^2 - 4^2\\\)
\(x^{2} = 56.25\)
\(x = \sqrt{56.25}\)
\(x = 7.5\)
The radius of the semicircle of BC = 7.5 Units.
Refer to this complete question for this:

which set of expo pens has a cheaper price the set of 8 which cost in total 11.57$ or the set of 4 which is 4.49
Answers
Answer:
the 4.49 ones.
Step-by-step explanation:
11.57 divided by 8 would result in each pen costing 1.44$ per pen. Meanwhile, dividing 4.49 by 4 would result in each pen costing 1.12$.
Answer: The second deal is cheaper
=========================================================
Explanation:
We're looking for the unit cost, which is the cost for one item (in this case, it's the cost of one pen). To get the unit cost, divide the total cost over the number of pens.
For the first deal, we have a unit cost of 11.57/8 = 1.44625 which rounds to 1.45 dollars.
The unit cost for the second deal is 4.49/4 = 1.1225 which rounds to 1.12 dollars. The second deal is the cheaper option due to 1.12 being smaller than 1.45
What is F(-x)?
F(x)=x^3+1
Answers
Answer:
F(-x) = 0
Step-by-step explanation:
What is F(-x)?
F(-x) = F(-1)
F(x) = x³ + 1 F(-1)
F(-1) = -1³ + 1
F(-1) = -1 + 1
F(-1) = 0
So, F(-x) = 0
Answer:
f(-1) = 0
Step-by-step explanation:
Evaluating a function for f(-x) is the same as evaluating it for f(-1).
So we plug in -1 instead.
f(-1) = x³ + 1
= (-1)³ + 1 (here we cube -1)
= -1 + 1 (here we subtract)
= 0 (and, this is the answer)
\(\therefore\) The answer is f(-1) = 0
