Answer:

the length of the diagonal AC is;

Explanation:

Given the parallelogram ABCD, diagonals AC and BD intersect at point E.

Recall that the diagonals of a parallelogram bisect each other;

So;

substituting AE and CE;

To calculate the length of AC;

Therefore, the length of the diagonal AC is;

Therefore, the scalar multiplication of vector -7/4 w is given by

Hence, the linear combination is 7/8 i + 21/8 j

In this case, we'll have to carry out several steps to find the solution.

Step 01:

data:

score:

mean = 76

standard deviation = 12

Step 02:

probability:

normal distribution:

normal distribution diagram:

mean + 1 standard deviation = 76 + 12 = 88

probability (class average score is above 80):

p (score > 80) = 34% + 13.5% + 2.4% + 0.1% = 50% = 0.5

The answer is:

p (score > 80) = 50% = 0.5

To find the area using four rectangles, we will use the following equation:

We have the inequality:

Let's find out 3 solutions, as follows:

3x - 4 > 5

Adding 4 at both sides of the inequality:

3x - 4 + 4 > 5 + 4

3x > 9

Dividing by 3 at both sides, we have:

3x/3 > 9/3

x > 3

Now, we can find 3 solutions that fulfill the condition of the inequality:

x = 4, x = 5, x = 6

These three solutions are > 3

∠1 is 31.5°

∠2 is 148.5°.

Given:

∠1 = x

∠2 = 5x-9

The measure of ∠1 and ∠2 are supplementary angles.

First, the value of x can be calculated as,

Substitute the value of x in ∠2.

Hence, the measure of ∠1 is 31.5° and the measure of ∠2 is 148.5°.

When you multiply two numbers, one of them greater than 0 and the other one lower than 1. The result is a number that is lower than the first one, that is, a number lower than the number greate than 0.

Answer:

Explanation:

To get the plot of h(x), we just plot the given values of y at the given values of x.

For example, we are told that between x = -3.5 and -2.5, h(x) = -3. Therefore, the plot gives

The hollow circle tells us that the value x = -3.5 itself is not included. The solid circle tells us that x = -.2.5 is included. All this comes from the fact that the interval given is -3.5 < x ≤ -2.5.

Using the same method for other entries on the graph, we get our desired plot.

Explanation:

By properties of logarithms, the logarithm of a fraction is equal to the difference of logarithms, so

Now, log₆(1) = 0 and log₆36 = 2, so

Therefore, the answer is -2

From the information given, the slope (m) of the equation is -1.5. This means that there is an inverse relationship between the Lenght of the Candle and the number of hours. Where, the longer the number of hours, the smaller the length of the candle. See further explanation below.

The slope of a line is its steepness as it goes from LEFT to RIGHT. The slope is the proportion of a line's rise, or vertical change, to its run, or horizontal change. The slope of a line is always fixed (it never changes) regardless of whatever two locations on the line are chosen.

When dealing with a linear relationship, the question is usually represented in this format:

y = mx + b; where
m = slope and

b= y-intercept (or constant)

From the case above, the equation shows the relationship between time   (t) the candle spends burning and the length of the candle (l).

Logically, we can infer that there will be a negative relationship between the two but first lets us determine the slope.

Restating the equation in intercept format, we have:

L = 15 - 1.5t................................1; in intercept format the slope we have

L = -1.5t + 15   ...........................2.

Where L [tex]\sim[/tex] y; m [tex]\sim[/tex] -1.5 and t [tex]\sim[/tex] x; and b [tex]\sim[/tex] 15

Hence we can state that the m (slope) = -1.5 and that if plotted on a graph, the line crosses the y-axis at y = 15 where x = 0.

Also, if L (that is y) is set to zero, then the total time taken for ALL the candles to burn is 10 hours.

See attached graph as proof.

The logical interpretation above is hence confirmed that there is an inverse relationship between x and y. This means that the longer the time, the shorter the length of the candle.

This also means that the length of the candle cannot be or is not longer than 15.

The slope of the equation is -3/2 describing the rate at which the length of the candle is decreasing.

We know lines have various types of equations, the general type is

Ax + By + c = 0.

We know slope is the rate of change of the y-axis with respect to the x-axis

also, rise over run which is (y₂ - y₁)/(x₂ - x₁).

The burning equation of the candle is represented by  L = 15 - 1.5t.

Where L = length of the candle and any point of time and t = time in hours.

Now, we'll need two points from this equation to obtain the slope.

At, t = 2, L = 12. and at t = 4, L = 9.

So, the two points are (2, 12) and (4, 9).

∴ Slope(m) = (9 - 12)/(4 - 2).

Slope(m) = -3/2.

The slope of this equation describes the rate at which the height of the candle is changing.

Let's begin by listing out the given information:

18 students passed

Total students = 25

Number of people who did not pass = 25 - 18 = 7

7 out of 25 students did not pass. This has its percentage as:

Therefore, 28% of the students did not pass

We solve as follows:

-12x - 2y = 30

2(-4x + y = -5)

---------------------

-12x -2y = 30

-8x + 2y = -10

--------------------

-20x = 20 => x = -1

Now we replace the value of x in one of the original equations to solve for y, that is:

-4(-1) + y = -5 => 4 + y = -5 => y = -9

So, the solution is the point (-1, -9).

SOLUTION

At the same time t,

Train 1 would have covered a distance of 80t, since distance = average speed x time.

Train 2 would have covered a distance of 70t.

Now both added should give 210 miles

That is 80t + 70t = 210

150t = 210

t = 210/150

t = 1.4 hours

We can consider

The subtraction of the mixed fractions and presenting the result in simplest form gives;

[tex] \displaystyle{9 \frac{2}{5} - 4 \frac{4}{5} = 14 \frac{1}{5}} [/tex]

A mixed fraction is one that has both a quotient part as a whole number, the remainder, as the numerator of the fraction part, and the divisor as the denominator of the fraction part.

The equation involves the subtraction of mixed fractions, which are expressed as follows;

[tex] \displaystyle{9 \frac{2}{5} - 4 \frac{4}{5} } = [/tex]

To subtract the mixed fractions, the mixed fraction can first be rearranged into improper fractions as follows;

[tex] \displaystyle{ \frac{5 \times 9 + 2}{5} - \frac{5 \times 4 + 4}{5} = \frac{47}{5} + \frac{24}{5} }[/tex]

[tex] \displaystyle{ \frac{47}{5} + \frac{24}{5} = \frac{71}{5} }[/tex]

The result of the addition of the improper fraction which is also an improper fraction can be rearranged into partial fractions again as follows;

71 = 5 × 14 + 1

Which gives;

[tex] \displaystyle{ \frac{71}{5} = 14 \frac{1}{5} }[/tex]

Therefore;

The required exponential function f(x) = (4)(2)ˣ which is passes through the two points (-1,2) and (3,32).

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

It is a relation of the form y = aˣ  in mathematics, where x is the independent variable

Let the formula for an exponential function would be as

⇒ f(x) = abˣ  

The exponential function passes through the two points (-1,2) and (3,32).

f(-1) = 2

f(3) = 32

2 = ab⁻¹

2b = a

32 = ab³

Substitute the value of a = 2b in the above equation,

32 = 2b×b³

32 = 2b⁴

b⁴ = 16

b⁴ = 2⁴

b = 2

Substitute the value of b = 2 in the equation a = 2b,

So a = 2×2 = 4

⇒ f(x) = (4)(2)ˣ  

Therefore, the required exponential function f(x) = (4)(2)ˣ

A dot plot shows the number of times that each observation appears on a data-set.

Hence the hours of the 5th-graders are as follows:

There are 24 elements in the data-set, hence the median is the mean of the 12th and the 13th element, as follows:

Median = (5 + 5)/2 = 5.
