Answer:

The multiplicative inverse is -5/3

Step-by-step explanation:

Multiplicative inverse means we want to end up with 1

-3/5 * what =1

Multiply by 5 to clear the fraction

-3/5 * what *5 = 1*5

-3 * what = 5

Divide by -3 to isolate what

-3*what /-3 = 5/-3

what = -5/3

The multiplicative inverse is -5/3

Answer:

101

Step-by-step explanation:

The theorem to use this is the intercepted arc theorem, which tells us that if we take 2 points on the circumference of a circle and create an angle in the opposite side of the circumference, that angle is HALF that of the ARC intercepted.

If we look at 100 degree angle, we see the ARC intercepted is 99 degree and a degrees. According to theorem, we can say:

99 + a = 2(100)

99 + a = 200

a = 200 - 99

a = 101

Answer:

(f-g)(x) = 4x - x^(-5)

Step-by-step explanation:

Please, enclose that negative exponent inside parentheses:  g(x)=x^(-5).  No need to type in the " + " in f(x)=4x^+1.

g(x) is to be subtracted from f(x).  Write f(x):

f(x)=4x

followed by the negative of g(x):  -g(x) = -x^(-5)

and now combine these two results:

 f(x)=4x

-g(x)= -x^(-5)

---------------------

(f-g)(x) = 4x - x^(-5)

The expression for (f-g)(x) is (f-g)(x) = 4x² + 1 - 1/x⁵

A function is a mathematical formula that describes how the dependent variable and independent variable are related. The dependent variable's value varies in the function together with the independent variable's value.

To find (f-g)(x), we need to subtract g(x) from f(x):

(f-g)(x) = f(x) - g(x)

We are given:

f(x) = 4x² + 1

g(x) = x⁻⁵ = 1/x⁵

Substituting these values into the expression for (f-g)(x), we get:

(f-g)(x) = f(x) - g(x) = (4x² + 1) - (1/x⁵)

Simplifying the expression, we can write:

(f-g)(x) = 4x^2 + 1 - 1/x⁵

Therefore, the expression for (f-g)(x) is:

(f-g)(x) = 4x² + 1 - 1/x⁵

Final answer:

To identify which function the graph represents, analyze the shape and pattern of the graph. The correct function could either be a polynomial such as y = x^4, which has a sharply rising curve, or a logarithmic function with a declining curve due to having a base between 0 and 1, like y = log(1/4)x, but not y = log1x as this is not mathematically valid.

Explanation:

The question requires the identification of a function based on its graph. Since the properties of functions are known, such as the logarithmic function increasing as x increases, and the behavior of exponential functions and their inverses, we can analyze the options given. The function y = log1x is not valid as the base of a logarithm cannot be 1. The function y = x4 is a polynomial function with a graph that rises sharply for positive and negative values of x. Lastly, y = log(1/4)x represents a logarithmic function with base 1/4, which is a declining curve because the base is between 0 and 1.

To choose the correct function that a graph represents, one should look for key characteristics such as the shape of the graph, increase or decrease pattern, as well as specific points like asymptotes or intercepts. If the graph is increasing as x increases and resembles a typical logarithmic curve, the correct choice is a logarithmic function. If the given graph is a sharp rising curve for all x-values and looks like a polynomial, then y = x4 would be correct. The given functions need to be analyzed based on their mathematical properties to select the one that best describes the graph in question.

Step-by-step explanation:

The seventh term of an AP is written as:

[tex]a + 6d[/tex]

The eleventh term of an AP is written as:

[tex]a + 10d[/tex]

If the 7th term is 11 times the 11th term, then;

[tex]a + 6d = 11(a + 10d)[/tex]

Expand to get:

[tex]a + 6d = 11a + 110d[/tex]

[tex]11a - a = 6d - 110d[/tex]

[tex]10a = - 104d[/tex]

[tex] \frac{a}{d} = - \frac{104}{10} [/tex]

[tex] \frac{a}{d} = - \frac{52}{5} [/tex]

Answer: OPTION C.

Step-by-step explanation:

You need to use this formula:

[tex]averate\ rate\ of\ change=\frac{f(b)-f(a)}{b-a}[/tex]

Knowing that we need to find the average rate of change for the given quadratic function, for the interval from [tex]x=-5[/tex] to [tex]x=-3[/tex], we need to find their corresponding y-coordinates.

We can observe in the graph that:

For [tex]x=b=-5[/tex] →  [tex]y=f(b)=-15[/tex]

For [tex]x=a=-3[/tex] → [tex]y=f(a)=1[/tex]

Therefore, substitituting, we get:

 [tex]averate\ rate\ of\ change=\frac{-15-1}{-5-(-3)}=8[/tex]

Answer:

Step-by-step explanation:

Let assume that x% = 200,000

Lets assume that 100 %  = 131,000,000 because it is the output value:

Therefore we have two equations:

x% = 200,000

100 %  =131,000,000

Now observe that the L.H.S of both the equations have same unit. So we can write it as:

100%/x% = 131,000,000/200,000

Now just simply solve the values:

Multiply both sides by x

100/x *x = 131,000,000/200,000 *x

100=655x

Now divide both the sides by 655.

100/655 = 655x/655

100/655=x

0.15267175572519=x

Therefore the answer is 200,000 is 0.15267175572519% of 131,000,000 ....

just an addition to the reply above, which is correct, so to the risk of sounding redundant.

if we take 131,000,000 to be the 100%, what is 200,000 off of it in percentage?  Bearing in mind that 1% of 131,000,000 is really 1,310,000, notice we simply chopped off two zeros, but that amount is larger than 200,000 and thus whatever 200,000 is, is less than 1%.

[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 131000000&100\\ 200000&x \end{array}\implies \cfrac{131000000}{200000}=\cfrac{100}{x}\implies \cfrac{1310}{2}=\cfrac{100}{x} \\\\\\ 1310x=200\implies x=\cfrac{200}{1310}\implies x\approx 0.1526717557251908[/tex]

Final answer:

The Pythagorean theorem relates the lengths of the legs and hypotenuse of a right triangle. By substituting the given values into the equation, we can solve for x using the theorem. The rounded value of x is 3.6 (B).

Explanation:

The Pythagorean theorem relates the length of the legs of a right triangle, labeled a and b, with the hypotenuse, labeled c. The relationship is given by: a² + b² = c². This can be rewritten, solving for c: c = √(a² + b²).

In this case, we want to find the value of x using the Pythagorean theorem. Let's say that the lengths of the legs are 3 and x. Substituting these values into the theorem, we have:

3² + x² = c²

Now, we can solve for x by rearranging the equation:

x² = c² - 3²

x = √(c² - 3²)

Rounding to the nearest tenth, we can find the value of x to be approximately 3.6 (B).

Final answer:

The Pythagorean theorem allows us to calculate the length of the hypotenuse of a right triangle by squaring the lengths of the other two sides, adding them together, and then taking the square root. To round to the nearest tenth, we calculate and then round the final result accordingly.

Explanation:

To use the Pythagorean theorem to find x and round to the nearest tenth, we need to establish the components of the equation. The theorem states that in a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). The formula is written as a² + b² = c².

However, the problem provided does not include the initial lengths to insert into the equation; hence, we cannot compute the value directly. Nonetheless, I can illustrate with a hypothetical example:

If we have a right triangle with legs of lengths 9 (a) and 6 (b), then the hypotenuse (c) can be found as follows:

c = √(9² + 6²)
c = √(81 + 36)
c = √117
c = 10.82, round off to the nearest tenth would be c = 10.8

In this example, we squared the lengths of the legs, added them together, and took the square root of the result to find the hypotenuse to the nearest tenth. The same steps apply to any right-angled triangle where you are given the lengths of the legs and need to find the hypotenuse using the Pythagorean theorem.

Answer:

3.7

Step-by-step explanation:

Inversely means we are taking the constant and dividing it.

So y varies inversely with x means "y=k/x".

k is a constant.  We can find the constant if they give us a point on this curve.

The constant is a number that doesn't change no matter your input and output.

[tex]y=\frac{k}{x}[/tex]

So they actually give us k=8.88 and y=2.4 so let's input this:

[tex]2.4=\frac{8.88}{x}[/tex]

We need to solve this equation for x.  You can do your favorite thing in cross-multiply. But how, Freckles?  Well just slap a 1 underneath that 2.4.  You can do that because 2.4/1 is still 2.4.

[tex]\frac{2.4}{1}=\frac{8.88}{x}[/tex]

Cross-multiply:

[tex]2.4x=8.88(1)[/tex]

[tex]2.4x=8.88[/tex]

Divide both sides by 2.4:

[tex]x=\frac{8.88}{2.4}[/tex]

[tex]x=3.7[/tex] when [tex]y=2.4[/tex].

Answer:

[tex] \sqrt{\frac{668}{\pi} } [/tex] feet  given the area is 167 ft squared

Step-by-step explanation:

Since our sector as a central angle of 90 degree then it is only a 4th of the whole circle.  The area of a circle is pi*r^2.  We will only be using a 4th of that since are sector is only a 4th of the circle.

So the formula will be using for the area of our sector is A=1/4 *pi*r^2.

We are given the area is 167 so replace A with 167.

167=1/4 * pi *r^2

Multiply both sides by 4.

167*4  =pi * r^2

668=pi * r^2

Divide both sides by pi

668/pi =r^2

Answer:

130°

Step-by-step explanation:

Since there are 360 degrees is a circle, measure of AXC = 260 means the measure of Arc AC is:

360 - 260 = 100

Now if we were to draw 2 lines, one from A to X and another from C to X, we would have an intercepted angle at X originating from AC.

The theorem is when the intercepted angle is at the opposite side of the circumference, the angle is HALF THAT OF THE ARC.

So, half of 100 is 50.

Angle X and Angle B add up to 180, hence Angle ABC is 180 - 50 = 130

Answer:

B

Step-by-step explanation:

The vertex form of an absolute value function is f(x)=a|x-h|+k where (h,k) is the vertex.

a is positive means the absolute value function will face up.

a is negative means the absolute value function will face down.

So looking at the picture we see the vertex is (2,3) and all of the choices have a is 1.

So plugging in 2 for h and 3 for k and 1 for a into f(x)=a|x-h|+k

f(x)=|x-2|+3.

A diagonal of a square divides the square into two congruent right isosceles triangles.

Let the sides of the square be 's' units. Then, the Pythagoras Theorem says that, the sum of the squares of the shorter legs will be equal to the square of the hypotenuse.

Let the diagonal which is the hypotenuse be 'd' units.
