Answer:

8 and 24

Step-by-step explanation:

let one no. be x

and another be 3x

Their sum = 32

Now,

x + 3x=32

4x=32

x=32/4

x=8

Hence, one number is x =8 and another is 3x = 3*8=24

The two numbers are 6 and 26

From the given statement, we can form the following equations;

Let the first number = x

let the second number = y

The  2 numbers that add up to 32:

x + y = 32 ---------- (1)

If one number is eight more than three times the other:

x = 3y + 8  -------(2)

Substitute the value of x into equation (1) and solve for the second number

3y + 8 + y = 32

4y = 32 - 8

4y = 24

[tex]y = \frac{24}{4} = 6[/tex]

The value of  the first number, x,  is calculated as;

x = 3(6) + 8

x = 18 + 8

x = 26

Thus, the two numbers are 6 and 26

Logarithm involves the use of exponents to represent numbers.

If the pH level of grape juice is 3.3, the hydronium ion concentration is [tex]5.01 \times 10^{-4[/tex]

Given that:

[tex]P = -\log(c)[/tex]

To calculate c when [tex]P = 3.3[/tex]

We first substitute 3.3 for P in [tex]P = -\log(c)[/tex]

So, we have:

[tex]3.3 = -\log(c)[/tex]

Divide both sides by -1

[tex]-3.3 = \log(c)[/tex]

Apply law of logarithm

[tex]10^{-3.3)} = c[/tex]

Rewrite as:

[tex]c = 10^{-3.3}[/tex]

Using a calculator, we have:

[tex]c = 0.000501[/tex]

Rewrite as

[tex]c = 5.01 \times 10^{-4[/tex]

Hence, the hydronium ion concentration is [tex]5.01 \times 10^{-4[/tex]

Matrix operations includes the addition, multiplication and subtraction of matrices

The correct option for the matrix that can be used to represent B is option D)

[tex]D) = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

The reason the above option is correct is as follows:

From the graph, we have that the coordinates of the preimage are;

(-6, 5), (-3, 9), and (6, 5)

The coordinates of the preimage in matrix form is given as follows;

[tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

The coordinates of the image are;

(-6, -5), (-3, -9), and (6, -5)

The coordinates of the image in matrix form is given as follows;

[tex]\left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

The above image matrix can be obtained from the primage matrix as follows:

[tex]\left[\begin{array}{rrr}1&0\\0&-1\end{array}\right]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right] = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

Which is of the form AB = C

Where;

[tex]A = \left[\begin{array}{rrr}1&0\\0&-1\end{array}\right][/tex]

[tex]B = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

[tex]C = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

Therefore, the matrix that could represent B is [tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex] which is option D)

They're parallel lines .

Step-by-step explanation:

But they are perpendicular to the lines they meet with. i.e; width lines are parallel to each other. But width lines are perpendicular to length lines.

[tex]{ \sf{}}[/tex]

Answer:

Parallel lines

Step-by-step explanation:

It wouldn't be perpendicular lines because a perpendicular line is when two lines come together to make a perfect corner, or 90 degree angle. It wouldn't be neither because parallel lines is when they face each other and if they were to go on forever they would never touch because they go straight. That may sound confusing but and example would be like the opposite lines on a square, how they're perfectly straight and opposite each other. The answer is parallel lines. Hope this helps! Good luck.

Answer:

x= (5X+3) DEGREES = 90 degrees (right angle)

5x=90 degrees - 3 degrees =87 degrees

5x÷5 =87 degrees ÷ 5

x=17.4 degrees

we now know our angles x = 17.4 degrees so we can know substitute into the give formula

wxz=5 (17.4)+ 3

wxz =90 degrees

zxy=we know the size of x

zxy=

8 (17.4)-4

zxy=135.2 degrees

Point (9, 6) would be on the inverse of this function so option (D) will be correct.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the sets of coordinates of a function.

An inverse function is the reciprocal of a function and the coordinate of the inverse function is interchanged with the original function.

For example, if (x,y) is the coordinate of the function then (y,x) will be the coordinate of the inverse of the function.

Since option (D) (9, 6) is the interchange of (6,9) so it will be the inverse of a function.

Hence "Point (9, 6) would be on the inverse of this function".

Answer:

AM=1 false

BM= ½ true

AM=½ false

BM= √3/2 false

AM= ✓3/2 true

BM=1 false

Step-by-step explanation:

Since the triangle is equilateral it means that all sides are of the same length. So AB=1, BC=1, AC=1

AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2

BM= ½ true because BC=1 so BM (half)=0,5=½

AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2

BM= √3/2 false because it's ½

AM= ✓3/2 true because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2

BM=1 false because BM= ½
