Switch the order of the x and y values in the ordered pairs.
O Create a table of values from the exponential function.
O Draw a connected line through the points to show the graph of the logarithmic function.
Graph the ordered pair of the exponential inverse function.

The option that rewrite the expression 1 / 3 + 2  / 5 using commutative law of addition is D.

The commutative property of addition states that a change in the order of the numbers being added does not affect the sum. In other words, when the order of a sum of values is changed, the commutative property of addition states that the sum of the numbers does not affect the sum of the numbers.

Therefore, let's use the commutative law of addition to rewrite 1 / 3 + 2  / 5.

Hence,

[tex]\frac{1}{3} + \frac{2}{5} = \frac{2}{5}+\frac{1}{3} = \frac{6+5}{15} = \frac{11}{15}[/tex]

Therefore, the answer is D.

Answer:

Step-by-step explanation:

The company should adopt the new tread pattern, as the test statistic is lower than the critical value.

For this problem, we will use a one-tailed hypothesis test to determine if the company should adopt the new tread pattern. The null hypothesis (H0) is that the tires will not allow a car traveling at 60 mph to come to a complete stop within an average of 125 feet after the brakes are applied. The alternative hypothesis (H1) is that the tires will allow a car traveling at 60 mph to come to a complete stop within an average of 125 feet after the brakes are applied.

The test statistic used here will be the mean of the sample set, which is 125.33 feet. We need to find the critical value to determine whether or not the company should adopt the new tread pattern. To do this, we will use a one-sample t-test with a significance level of 0.05.

After taking into account the outlier (102 feet), the critical value is 1.711. Since the test statistic (125.33) is lower than the critical value (1.711), we can reject the null hypothesis and conclude that the company should adopt the new tread pattern. The outlier was accounted for by performing a one-tailed hypothesis test rather than a two-tailed hypothesis test. This allowed us to look at the data in the context of a single direction (whether or not the tires meet the objective), so that the outlier did not affect the results.

The company should adopt the new tread pattern, as the test statistic is lower than the critical value.

Measure of each missing angles are,

⇒ ∠EFC = 51°

⇒ ∠DFG = 51°

⇒ ∠HEF = 36°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.  

We have to given that;

⇒ m ∠CFG = 129°

⇒ m ∠HFD = 93°

Now, By figure EFG make a linear line.

So, We get;

⇒ ∠EFC + ∠CFG = 180°

⇒ ∠EFC + 129° = 180°

⇒ ∠EFC = 180° - 129°

⇒ ∠EFC = 51°

In the figure, Measure of ∠EFC and ∠DFG are vertically opposite angle.

Hence, Both are equal.

⇒ ∠DFG = ∠EFC = 51°

Here, EFG make a linear line.

Hence, We get;

⇒ ∠HEF + ∠HFD + ∠DFG = 180°

Substitute all the values, we get;

⇒ ∠HEF + 93° + 51° = 180°

⇒ ∠HEF + 144° = 180°

⇒ ∠HEF = 180° - 144°

⇒ ∠HEF = 36°

Thus, Measure of each missing angles are,

⇒ ∠EFC = 51°

⇒ ∠DFG = 51°

Ratios show that Julie earns 50% more than Simon, and John earns 12.5% less than Julie.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Lets divide each salary by 1,000 to express the salaries in thousands of rands:

Simon earns 4,000 / 1,000 = 4,000

Julie earns 6,000 / 1,000 = 6,000

John earns 3,500 / 1,000 = 3,500

Now, we can compare the salaries by expressing them as ratios:

Simon: Julie = 4,000 : 6,000 = 2 : 3

Julie: John = 6,000 : 3,500 = 6 : 3.5

Simon: John = 4,000 : 3,500 = 4 : 3.5

Hence, ratios show that Julie earns 50% more than Simon, and John earns 12.5% less than Julie.

To find the value of x for which the function f(x) = -4x^2 + 8x + 10 reaches its global maximum, we need to find its critical points.

First, we find the derivative of the function:

f'(x) = -8x + 8

Next, we set f'(x) = 0 and solve for x:

-8x + 8 = 0

-8x = -8

x = 1

This is the critical point. To determine whether this critical point corresponds to a maximum or a minimum, we look at the second derivative of the function:

f''(x) = -8

Since f''(x) is negative, this critical point corresponds to a maximum.

Therefore, the value of x for which the function f(x) = -4x^2 + 8x + 10 reaches its global maximum is x = 1.

The number of revolutions made by larger pulley is,  1032

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Given that,

A pulley has a diameter of 8 inches,

And it is belted to a pulley that has a diameter of 12 inches,

the speeds of the pulleys vary inversely to their diameters,

The smaller pulley running at speed of 1,548 revolutions per minute,

The larger pulley running at speed = ?

V α 1/d

Now, it can be written as,

V₁ α  1/d₁

V₂ α 1/d₂

1548 α  1/8

V₂ α 1/12

For removing proportionality sign,

It required to add one constant k,

1548 =  k(1/8)    _____(i)

V₂  = k (1/12)     _____(ii)

Now, by dividing both the equations,

V₂/1548   = k x (1/12)/ k x(1/8)  

V₂/1548 = 8/12

V₂ = 8/12 x 1548

V₂ = 1032

Hence, the RPM of larger pulley is  1032

Answer:

the length of the median of the triangle is 6√(5) cm.

Step-by-step explanation:We can start by using the Pythagorean theorem to find the length of the base of the triangle. Since the altitude of the triangle is 12 cm, the length of the median that divides the triangle into two smaller triangles with perimeter 20 cm can be found using the Pythagorean theorem as follows:

Let's call the length of the base "b". Then, the length of the median "m" is equal to the square root of the sum of the squares of half the base and the height:

m = √((b/2)^2 + 12^2)

We know the perimeter of the triangle is 24 cm, so:

b + 2m = 24

We can substitute b = 24 - 2m into the equation for m:

m = √(((24 - 2m)/2)^2 + 12^2)

Expanding and simplifying the equation gives:

m = √(6^2 + 12^2) = √(36 + 144) = √(180) = 6√(5) cm

So the length of the median of the triangle is 6√(5) cm.

Answer:

Step-by-step explanation:

From the picture below we are given a right angle triangle and asked to find the value of x. We can use the SOHCAHTOA principle to find the side x.

Base on the angle given the adjacent side of the triangle is x while the hypotenuse is given as  4 cm. Let's find the value of x .

cos 55° = adjacent/hypotenuse

cos 55° = x/4

cross multiply

x = 4 cos 55°

x = 4 × 0.57357643635
