Step-by-step explanation:

the radius cuts the segment into two equal parts because it is perpendicular to the chord

Answer:

Step-by-step explanation:

As O is the mid point of the circle

Similarly, B also becomes the mid point of the line AC.

So, line OB divides AB and BC equally.

Hence, lines AB = AC, but they are asking to prove congruency of triangles.

So, u have to join OA and OC.

Same way,   line OB divides ∠OBA and ∠OBC.

So it is proved that AB = AC

Answer:

The perimeter of the triangle is about 17.1 units.

Step-by-step explanation:

The perimeter of a triangle is the sum of its three side lengths.

We can see that the two legs of the triangle both measure five units.

To find the third segment, we can use the Pythagorean Theorem since the x-axis is perpendicular to the y-axis. Recall that:

[tex]a^2 + b^2 = c^2[/tex]

Where a and b are the two legs and c is the hypotenuse.

Our two legs are 5 and 5. Hence:

[tex](5)^2 + (5)^2 = c^2[/tex]

Solve for the hypotenuse:

[tex]\displaystyle \begin{aligned} c &= \sqrt{(5)^2 + (5)^2} \\ &= \sqrt{2(5)^2} \\ &= 5\sqrt{2}\end{aligned}[/tex]

Hence, our perimeter will be:

[tex]\displaystyle P = 10 + 5\sqrt{2} \approx 17.1 \text{ units}[/tex]

In conclusion, the perimeter of the triangle is about 17.1 units.

Weighted average is the average of a set using different weight for each element in the set. The final grade when homework and test scores are 59 and 64 is 62.35

Given that:

[tex]Homework = 59[/tex]

[tex]Test = 64[/tex]

The test score is greater than the homework score. So, the test will be weighted using 67%, while the homework will be weighted using 33%.

The final grade is calculated as follows:

[tex]Grade = 67\% \times Test + 33\% \times Homework[/tex]

So, we have:

[tex]Grade = 67\% \times 64 + 33\% \times 59[/tex]

[tex]Grade = 42.88 + 19.47[/tex]

[tex]Grade = 62.35[/tex]

Hence, the final grade is 62.35

Step-by-step explanation:

For every clockwise 90-degree rotation on a point (x, y), the resulted transformation will be (y, -x).

Now, counterclockwise 270 degree rotation is equivalent to clockwise 90 degree rotation. Then, for instance, point H=(2 ,-1) will be transformed into the image H'=( -1,2)

Answer:

265x{2} + 40x

Step-by-step explanation:

Squared mean to multiply the number times itself. So 15x times 15x.

[tex]15x^{2} = 225x[/tex]{2}

Then the problem says to add, but because one is squared and th other is not, they cannot be combined. So the answer is:

[tex]225x{2} + 40x

Answer:

see below

Step-by-step explanation:

15x^2 + 40x

These are not like terms so they cannot be combined.

If you mean

(15x) ^2 + 40x

(15x * 15x) + 40x

225x^2 + 40x

They are still not like terms so they cannot be combined.

Answer:

2(x^2)-1

Step-by-step explanation:

The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.

Hope this helps! :D

The expression "1 less than twice the square of a number" can be represented mathematically as [tex]\(2x^2 - 1\)[/tex], where x is the variable representing the number.

Expression: [tex]\(2x^2 - 1\)[/tex]

Step 1: Square the number x:

[tex]\((x)^2 = x^2\)[/tex]

Step 2: Multiply the squared number by 2:

[tex]\(2 \cdot x^2 = 2x^2\)[/tex]

Step 3: Subtract 1 from the result of step 2:

[tex]\(2x^2 - 1\)[/tex]

This is the final expression that represents "1 less than twice the square of a number."

For example, if we substitute a specific value for x, let's say x = 3:

Step 1: Square the number: [tex]\(3^2 = 9\)[/tex]

Step 2: Twice the squared number: [tex]\(2 \cdot 9 = 18\)[/tex]

Step 3: Subtract 1: 18 - 1 = 17

So, when x = 3, the expression [tex]\(2x^2 - 1\)[/tex] evaluates to 17.
