Find the ordered pair that is a member of both -6x + 3y = 84 and
-6x - 3y = 24 or indicate if it does not exist or there are infinite
possibilities.

x = 112 degrees.

A full triangle is 180 degrees total so do 180 - (39 + 29) = 112.

y = 220 degrees.

The sum of exterior angles are 360 degrees so 360 - 140 = 220.

The statement that explains how mental math can be used to find how much farther Josh rode than Claire is that to round 11.4 to 11. Round 6.8 to 7. Then subtract 7 from 11 to get 4. Josh rode 4 miles farther than Claire. That is option A.

The use of metal maths is simply the calculation of a given mathematical problem without the use of an aid such as electronic devices.

The number of miles covered by Josh = 11.4 miles

The number of miles covered by Claire = 6.8 miles

To use mental maths, the values are rounded up to the nearest whole number and the difference between the two are gotten.

That is;

11.4 = 11

6.8 = 7

Therefore the difference in the distance between the two individuals = 11-7 = 4 miles.

Step-by-step explanation:

Answer: [tex]533 yd^{2}[/tex]

Step-by-step explanation:

The surface area of the base is:

(20 x 17.3) / 2

= 346 / 2

= 173

The surface area of one of the three identical triangles is:

(20 x 12) / 2

= 240 / 2

= 120

So in total, your answer would be one base plus three of those identical triangles:

173 + (3 x 120)

= [tex]533 yd^{2}[/tex]

The equation of line is y = -50x + 150

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Points:(1, 100) (2, 50) (4, 25), (5, 20)

so, the slope is

= (50-100)/ (2-1)

= -50 /1

= -50

using slope intercept form

y - 100 = m (x- 1)

y- 100 = -50(x-1)

y- 100 = -50x + 50

y = -50x + 50 + 100

y = -50x + 150

Hence, the equation of line is y = -50x + 150.

The translation means that the x coordinate is moving 4 units to the right and the y coordinate is moving9 units to the right.

A translation in mathematics does not turn a shape; instead, it moves it left, right, up, or down. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes. They have only changed their direction or directions. The shape just shifts from one place to another, therefore there is no change in the shape.

The trigonometric function equation obtained for the graph is y = 4 sec (πx) - 2.

What is trigonometric function?

Simply put, trigonometric functions also referred to as circular functions are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle.

The upper waver have a value of y = 2 and the lower waves have a value of  y = -6.

Add the points and divide by 2 -

[2 + (-6)] / 2

(2 - 6) / 2

-4 / 2

-2

Therefore, the midline is y = -2.

The vertical asymptotes are drawn and they intersect the midline at certain points.

Then the sinusoidal function is drawn using the intersection point.

There is one period of sinusoidal function that is starting from x = 0 and goes upto x = 2.

This pattern tells that the function is of cosine.

Then the graph will be of trigonometric function secant .

The value of C = -2 , A = 4, D = 0

Here C is the midline value, A is the points above and below the midline, D is the horizontal shift and 2π/B is the period.

Now, 2π/B = 2

2B = 2π

B = π

Now, use the formula -

y = A cos (B(x - D)) + C

y = 4 cos (π(x - 0)) - 2

y = 4 cos (πx) - 2

y = 4 sec (πx) - 2

Now plot the graph for the obtained function.

Step-by-step explanation:

The expected phenotypes for the offspring is All tall.

Mendel came to the conclusion that some features predominated over other inherited traits when he noticed that a heterozygote offspring might exhibit the same phenotype as the parent homozygote. However, the connection between genotype and phenotype is rarely as straightforward as Mendel's descriptions of dominant and recessive patterns.

Given:

One is short and one is tall, Tall is dominant.

When two plants that are tall and short are crossed. They would all produce tall plants as a result, T.

The first crossing produced these children.

As a result of their parents' TT and SS genes, they all now have TS genes.

There will be some towering and some short off springs when these off springs are crossed. TS and TS will cross at this location. Given that they are all genetically tall and short.

So, The ratio of tall to short children they would have according to Mendel is 3:1.

The total time they spent traveling was 9 hours, so we can set up an equation:

t + 2t = 9

13 is a factor that is more than 4 and less then 26

The factor of the number 26 that is between 4 and 26 is 13. Factors are the numbers that can divide into a number without leaving a remainder. In this case, the factors of 26 are 1, 2, 13, and 26.

In mathematics, a factor of a number is a number that divides into another number without leaving a remainder. In the case of the number 26, its factors include 1, 2, 13, and 26. The factor of 26 that is between 4 and 26 is 13.

To find this, you can go through the factors of 26 one by one. The factors are found by dividing 26 by all the numbers up to 26, and the numbers that give a remainder of 0 are the factors. In this case, 1, 2, 13, and 26 divide evenly into 26, and so are the factors of 26. Of these, only 13 lies between 4 and 26.

Answer:

working on a answer one second

Step-by-step explanation:

The required probability is 0.8945 that a sample of 29 smoke detectors will have a mean lifetime between 57 and 64 months.

To find the probability that a sample mean is between 57 and 64 months, we need to find the standard deviation of the sample mean, which is given by the standard deviation of the population divided by the square root of the sample size.

The standard deviation of the sample mean = standard deviation of the population / square root of sample size = 8 / √(29) = 8 / 5.385 = 1.48

Next, we need to standardize the interval of 57-64 months by subtracting the mean and dividing it by the standard deviation of the sample mean.

z₁ = (57 - 60) / 1.48 = -2.03

z₂ = (64 - 60) / 1.48 = 1.35

Finally, we can use a standard normal table to find the area under the normal curve between z₁ and z₂, which gives us the probability of a sample mean falling in the interval (57, 64).

P(57 < X < 64) = P(-2.03 < Z < 1.35) = 0.9790 - 0.0845 = 0.8945

Therefore, the final answer is 0.8945, rounded to four decimal places.

Answer:

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{2}[/tex] x + 3 ← is in slope- intercept form

with slope m = [tex]\frac{1}{2}[/tex]

• Parallel lines have equal slopes , then

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

to find c substitute (2, - 4 ) into the partial equation

- 4 = [tex]\frac{1}{2}[/tex] (2) + c = 1 + c ( subtract 1 from both sides )

- 5 = c

y = [tex]\frac{1}{2}[/tex] x - 5 ← equation of parallel line

Answer:

X=7

Step-by-step explanation:

To solve this equation, we need to use the logarithmic properties. First, we can use the property loga(bx) = x loga(b) to rewrite the equation:

log3(5) + log3(x) = log3(35)

This can be rewritten as:

log3(5x) = log3(35)

Using the property loga(b) = c, we can re-write the equation as:

x = 35/5

Now, we can calculate the value of 35/5:

35/5 = 7

Therefore, the solution to the equation is x = 7.
