Step-by-step explanation:

We know that <YPC and angle <YPX are congruent angles. They are both 90°.

Side YP is congruent to YP, so these sides are congruent in both triangles.

<XYP and <YPZ are congruent, because the perpendicular bisector cuts <XYZ in two equal parts.

the graph of linear f passes through the point 1 -9 and has a slope of -3 what is the zero of f
(A) 2
(B) 4
(C) -6
(D) -2

Answers

Answer:

Step-by-step explanation:

Given the following data;

Points on the graph (x1, y1) = (1, -9).

Mathematically, the equation of a straight line is given by the formula;

y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

To find the zero of the linear function f, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - (-9) = -3(x - 1)

y + 9 = -3x + 3

y = -3x + 3 - 9

y = -3x -6 = mx + c

Intercept (c) or zero of a function = -6

Y intercept and slope

Answers

Answer: A y-intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system.

Slope - A number that describes both direction and steepness of the line.

Step-by-step explanation: If a line intersects the y-axis at point 5 then its y-intercept will be c= 5. As we denote y-intercept with c.

The slope is denoted by m.

Answer:

Step-by-step explanation:

Write an equation that represents a discount of 18% on a retail price of $55. Let p represent the new price. f

Answers

An equation that represents a discount of 18% on a retail price of $55 can be written as follows:

p = 0.82 * 55

In this equation, p represents the new price after the discount has been applied, and 0.82 represents the percentage of the original price that remains after the discount has been applied (100% - 18% = 82%).

Solving this equation, we find that the new price, p, is equal to $45.90.

Note: This equation represents a discount, which means that the final price, p, will be less than the original price. If you want to represent a markdown (i.e., a price increase), you would use a value greater than 1 for the percentage factor (e.g., 1.18 for a markdown of 18%).

The equation here is 0.88

If the first term is 6 and the conversation was 2, what is the seventh term of a geometric sequence? NO LINKS!!!!
A. 384
B. 2824
C. 192

Answers

Answer:

Step-by-step explanation:

Assuming you mean common ratio is 2

The nth term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 6 and r = 2 , then

a₇ = 6 × [tex]2^{6}[/tex] = 6 × 64 = 384 → A

For each language L1 to L5, described below, you need to do the following:
• Create a regular expression that defines the language accurately.
The alphabet A = {a, b} will be used.
The languages are:

2. L2 which has an odd number of as and an even number of bs.
3. L3 which contains exactly two as or exactly two bs, although not necessarily adjacent.
4. L4 which has all the bs appearing before any of the as, or all the as appearing before any of the bs.
5. L5 where there can be any number of as but the number of bs must be even, although the bs do not have to be adjacent.

What is a geometric sequence?

In Mathematics, a geometric sequence can be defined as a series of real and natural numbers that are calculated by multiplying the next number by the same number (common or constant ratio) each time.

How to calculate the nth term of a geometric sequence?

In Mathematics, the nth term of a geometric sequence can be calculated by using this mathematical expression:

aₙ = a₁rⁿ⁻¹

Where:

aₙ represents the nth term of a geometric sequence.r represents the common ratio.a₁ represents the first term of a geometric sequence.

Assuming the variable x represents the number of ticket sold previously (initial year) and it sold 7 times as many tickets each year as it did the year before, a mathematical expression which models this situation is given by geometric sequence:

x, 7x, 49x, 343x, .....

Check:

7/1 = 49/7 = 343/49 = 7 (proof).

Therefore, this is a geometric sequence.

Two tourists start walking across the Golden Gate Bridge at the same time but from opposite
ends. One of the tourists is walking at a leisurely rate of 0.9 meters per second, and the other
is walking at a rate of 1.1 meters per second. Given that the bridge is 2,738 meters in length,
how long will it take for the tourists to meet?
minutes and
seconds

Answers

Answer:

The tourists will meet at the midpoint of the bridge, which is 2738/2 = 1369 meters from each end.

At their respective walking speeds, it will take the first tourist 1369/0.9 = 1521.67 seconds to reach the midpoint, and it will take the second tourist 1369/1.1 = 1242.73 seconds.

Therefore, it will take them a total of 1521.67 + 1242.73 = 2764.4 seconds to meet.

Since there are 60 seconds in a minute, the time in minutes is 2764.4 / 60 = 46.07 minutes.

Therefore, it will take the tourists 46 minutes and 0.4 seconds to meet.

On solving the provided question we cans ay that - here in linear equation, y = 3 and x = -1/2

What is a linear equation?

The algebraic equation y=mx+b is known as a linear equation. B is the y-intercept, and m is the slope. The previous sentence, where y and x are variables, is commonly referred to as a "linear equation in two variables." Bivariate linear equations are those that contain two variables in them. The linear equations 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3 are examples. When an equation has the formula y=mx+b, with m denoting the slope and b the y-intercept, it is referred to as being linear.

y = 2x + 1 - linear equation.

value of y;

[tex]x = 0\\y = 2(0) + 1\\y = 2 + 1\\y = 3[/tex]

value of x;

[tex]y = 0\\0 = 2x + 1\\2x = -1\\x = -1/2[/tex]
