Answer:

John gave Fred $48

Step-by-step explanation:

Let

x be the amount of dollars John gave fred

y1 be the amount of dollars Fred has at the end

y2 be the amount of dollars John has at the end

Fred has

y1 = - $12 + x

John has

y2 =  $84 - x

y1 = y2

- $12 + x =  $84 - x

2*x = $96

x = $48

The circumference of the circle is found using the formula C = 2 PI r

Circumference = 2 *PI * 15.5 = 31pi

The angle is 90 degrees, which is 1/4 of a complete circle ( 360 degrees).

The arc length would be 1/4 of the circumference:

Arc length = 31pi / 4 = 7.75PI

Answer:

x=4±9i

Step-by-step explanation:

Solve the equation for x by finding a, b, and c of the quadratic then use the qaudratic formula

Answer:

[tex]x=4-9i[/tex] or  [tex]x=4+9i[/tex]

Step-by-step explanation:

The given equation is

[tex]x^2-8x+97=0[/tex]

By comparing to [tex]ax^2+bx+c=0[/tex], we have a=1,b=-8 and c= 97.

The quadratic formula is;

[tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]

We substitute the values to obtain;

[tex]x=\frac{--8\pm\sqrt{(-8)^2-4(1)(97)} }{2(1)}[/tex]

[tex]x=\frac{8\pm\sqrt{-324} }{2}[/tex]

[tex]x=\frac{8\pm18i }{2}[/tex]

[tex]x=4\pm9i[/tex]

Therefore [tex]x=4-9i[/tex] or  [tex]x=4+9i[/tex]

Answer:

Option D.

Step-by-step explanation:

Precision refers to the the level of measurement and exactness of a measurement. The mean diference between 'precision' and 'exactness' is that  if a measuring device gives consisten measurements it's considered precise, but it's not necessarily accurate.

For example, a measurement of 2.365m is more precise than a measurement of 2.3m, given that 2.365m has more significant figures and was made with an instrument that has higher precision. This doesn't mean that the measurement is accurate, the real value could be 3m for example! ✅

Answer:

The missing value is [tex]18.41\°[/tex]

Step-by-step explanation:

Let

x-----> the angle (missing value)

we know that

[tex]sin(x)=\frac{6}{19}[/tex]

therefore

[tex]x=arcsin(\frac{6}{19})=18.41\°[/tex]

[tex] \frac{x + 1}{x - 1} > 0 \\ [/tex]

multiply both sides by the x-1 to get rid of the fraction.

[tex]x + 1 > 0 \\ because \: x - 1 \times 0 = 0[/tex]

subtract 1 from each side

x>-1

The solution is

x<−1

x>1

ANSWER

[tex]{f}^{ - 1}( f(x)) = f( {f}^{ - 1} ( x)) = x[/tex]

EXPLANATION

The given functions are;

[tex]f(x) = \frac{1}{2} x[/tex]

[tex] {f}^{ - 1} (x) = 2x[/tex]

[tex]f( {f}^{ - 1} (x)) = f(2x)[/tex]

[tex]f( {f}^{ - 1} (x)) = \frac{1}{2} \times 2x = x[/tex]

Also,

[tex] {f}^{ - 1}( f(x)) = {f}^{ - 1} ( \frac{1}{2} x)[/tex]

[tex]{f}^{ - 1}( f(x)) = 2 \times \frac{1}{2} x = x[/tex]

In general,

[tex]{f}^{ - 1}( f(x)) = f( {f}^{ - 1} ( x)) = x[/tex]

Answer:

C. [tex]x>0[/tex]

Step-by-step explanation:

Given: [tex]f(x)=log(8x)[/tex]

To find the domain of a logarithmic function, we need to take the argument, 8x, and set it greater to zero. This is because an argument of a logarithmic function cannot be zero or negative.

[tex]8x>0[/tex]

[tex]x>0[/tex]

So since x is greater than zero, we have just found out our domain:

Interval Notation: (0, ∞)

Set Notation: {[tex]x|x>0[/tex]}

The domain of the logarithmic function is,

⇒ x > 0

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that:

The function is,

⇒ F (x) = log₈ x

Now, To find the domain of a logarithmic function, we need to take the term, 8x, and set it greater to zero.

This is because an argument of a logarithmic function cannot be zero or negative.

Hence, We get;

8x > 0

x > 0

Thus, The domain of the logarithmic function is,

⇒ x > 0

Answer:

c = 5

Step-by-step explanation:

This is the classic problem that the ancients (particularly the Egyptians) used extensively. When the Nile over flowed in spring, the land had to be reclaimed and  surveyed in the early summer for planting. The 3-4-5 triangle was used to determine right angles for surveying purposes.

Formula

c^2 = a^2 + b^2

Givens

a = 3

b = 4

c = ?

Solution

c^2 = 3*3 + 4*4

c^2 = 9 + 16

c^2 = 25

Take the square root of both sides

To take the square root on your calculator, find the √ on the key pad. Some calculators give it a key and some have the symbol on the body of the calculator. If has its own key do it like this.

Answer

c = 5

The hypotenuse c of a right triangle with legs a = 3 and b = 4 can be found using the Pythagorean theorem, yielding c = 5

To solve for c, the hypotenuse of a right triangle when given the legs a and b, we utilize the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). This is expressed as a² + b² = c².

To solve for c when a = 3 and b = 4, we substitute these values into the theorem to get 3² + 4² = c², which simplifies to 9 + 16 = c². When we combine the values we get 25 = c². Finally, we take the square root of both sides to solve for c, resulting in c = 5.

Answer:

I believe your answer is 429.

Step-by-step explanation:

5 1/2 x 6 1/2 x 12 = 429

The numbers are 19 and 28.

Answer:

28 and 19

Step-by-step explanation:

let the 2 numbers be x and y, x > y, then

x + y = 47 → (1) ← sum of numbers

x - y = 9 → (2) ← difference of numbers

Adding the 2 equations to eliminate y

2x = 56 ( divide both sides by 2 )

x = 28

substitute x = 28 into (1) and solve for y

28 + y = 47 ( subtract 28 from both sides )

y = 47 - 28 = 19

The 2 numbers are 28 and 19

1 1/3x=-8/3

Answer:

x=−2 is the answer

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2/3(x - 4) = 2x

(2/3) (x) + (2/3) (-4) = 2x      Distributed

2x/3  +  -8/3 = 2x

Step 2: Subtract 2x from both sides.

2x/3 + -8/3 = 2x

(2x/3) (-2x/1)  + -8/3 =0

-4x/3 + -8/3 = 0

Step 3: Add 8/3 to both sides.

-4x/3 = 8/3

Step 4: Multiply both sides by 3/(-4).

(3/-4)  (-4x/3) = ( 3/-4)  (8/3)

X= -2 because 3 x 8= 24   and  -4 x 3 = -12

24 Divided by -12 give -2

Answer:

Yes, y varies directly with x, and the equation is [tex]y=1.6x[/tex].

Step-by-step explanation:

To check where there is a direct relationship between x and y, we need to check whether all the x,y pairs we have fit some rule:

[tex]y=k\times x[/tex].

For the first pair (x=4, y=6.4),

[tex]6.4=k\times 4[/tex]

Therefore [tex]k = 1.6[/tex].

For the second pair (x=7, y=11.2),

[tex]11.2=k\times 7[/tex]

Therefore [tex]k = 1.6[/tex].

For the third pair (x=10, y=16),

[tex]16=k\times 10[/tex]

Therefore [tex]k = 1.6[/tex].

For the second pair (x=13, y=20.8),

[tex]20.8=k\times 13[/tex]

Therefore [tex]k = 1.6[/tex].

So x does directly vary with y, and we have found out that [tex]k=1.6[/tex].

Answer:   [tex]\bold{\dfrac{y}{x}=1.6\quad \text{which is also equivalent to}\quad y=1.6x}[/tex]

Step-by-step explanation:

[tex]\begin {array}{c|c||l}x&y&\dfrac{y}{x}=k\\--&--&-----\\4&6.4&\dfrac{6.4}{4}=1.6\\\\11.2&7&\dfrac{11.2}{7}=1.6\\\\10&16&\dfrac{16}{10}=1.6\\\\13&20.8&\dfrac{20.8}{13}=1.6\\\end{array}\\[/tex]

Since the k-value is the same for every value in the table, we can conclude that y varies directly with x and the constant of variation k = 1.6

Answer: Option a.

Step-by-step explanation:

1. Multiply the numerator and the denominator of the expression shown in the image, by the conjugate of the denominator ( [tex]\sqrt{x}-\sqrt{7}[/tex]), as you can see below:

[tex]\frac{(\sqrt{x})(\sqrt{x}-\sqrt{7})}{(\sqrt{x}+\sqrt{7})(\sqrt{x}-\sqrt{7})}[/tex]

2. By definition, you know that:

[tex](a+b)(a-b)=a^2-b^2[/tex]

3. Therefore, you obtain the following result:

[tex]\frac{(\sqrt{x})^2-\sqrt{7x}}{(\sqrt{x})^2-(\sqrt{7})^2}=\frac{x-\sqrt{7x}}{x-7}[/tex]

Then, the answer is option a.

The answer is:

a. [tex]\frac{x-\sqrt{7x}}{x-7}[/tex]

Rationalizing involves eliminating or the roots of both numerator and denominators, there are severals ways to do it but one of the most common methods is using the conjugate term.

We must remember that:

[tex](a-b)(a+b)=a^{2}-b^{2}[/tex]

So, for the given expression:

[tex]\frac{\sqrt{x}}{\sqrt{x}+\sqrt{7}}[/tex]

The conjugate is:

[tex]\sqrt{x}-\sqrt{7}[/tex]

The, we need to multiply both numerator and denominator (in order to not affect the expression) by the conjugate expression in order to eliminate the radicals in the denominator:

[tex]\frac{\sqrt{x}}{\sqrt{x}+\sqrt{7}}*\frac{\sqrt{x}-\sqrt{7}}{\sqrt{x}-\sqrt{7}}=\frac{(\sqrt{x})*(\sqrt{x}-\sqrt{7})}{(\sqrt{x}+\sqrt{7})*(\sqrt{x}-\sqrt{7})}[/tex]

[tex]\frac{(\sqrt{x})*(\sqrt{x}-\sqrt{7})}{(\sqrt{x}+\sqrt{7})*(\sqrt{x}-\sqrt{7})}=\frac{(\sqrt{x})^{2}-(\sqrt{x})*(\sqrt{7})}{(\sqrt{x})^{2}-(\sqrt{7})^{2}}[/tex]

[tex]\frac{(\sqrt{x})^{2}-(\sqrt{x})*(\sqrt{7})}{(\sqrt{x})^{2}-(\sqrt{7})^{2}}=\frac{x-\sqrt{7x}}{x-7}[/tex]
