Answer:

9 m²

Step-by-step explanation:

s = half the perimeter = (a+b+c)/2

the perimeter in our case is

a+b+c = 16

so, s = 16/2 = 8

and the sides are

7 m

6 m

16 - 7 - 6 = 3 m

therefore, we get

area = sqrt(8(8-7)(8-6)(8-3)) = sqrt(8×1×2×5) = sqrt(80) =

= 8.94427191... ≈ 9 m²

Answer:

60

Step-by-step explanation:

Let's call the number A.

We are told that:

(2/3)A - 8 = 32

Multiply both sides by 3 and rearrange:

3*[(2/3)A - 8 = 32]

2A - 24 = 96

2A = 120

A = 60

CHECK:

Does (2/3) of 60 minus 8 equal 32?

(2/3)*(60) = 40

40 - 8 = 32

YES

The number is 60

Answer:

Step-by-step explanation:

f(-2) means that the "x" variable in the equation can be substituted for -2

So, we have

-5(-2) + 12

This equals 10 + 12 = 22

So, the answer is 22

Answer:

x = 4

Step-by-step explanation:

the two angles you see are alternate exterior angles, meaning they are equal to eachother.

32x + 2 = 33x - 2

subtract so that x is on one side. 33 - 32 = 1, so the equation would be

2 = x - 2

add 2 to both sides.

4 = x

hope i helped.

Answer:

x = 16x

Step-by-step explanation:

32x divided by 2 equals 16x

33x minus 2 also equals 16x

Since the numbers are the same for both equations X equals 16x

Answer:

x = -5

Step-by-step explanation:

We can use the below formula to find the line of symmetry.

( x - a )² + b

Here,

line of symmetry = +a

Vertex = +b

And now let us take a look at the given equation.

y = x² + 10x + 22

To find the line of symmetry from the given equation we have to make the given equation as the given formula.

Let us use the completing square method for that.

y = x² + 10x + 22

Put zero instead of y.

x² + 10x + 22 = 0

x² + 10x = -22

x² + 10x + 25 = -22 + 25

( x + 5 )² = 3

( x + 5 )² -3 = 0

Therefore,

line of symmetry of the line is = -5

∴ x = -5

Step-by-step explanation:

35 divided by 60 is = 0.583333

which is a repeating decimal

Among the options, only a rational number (35/60) is equivalent to a repeating decimal. The correct answer is option (d).

To identify which of the given rational numbers is equivalent to a repeating decimal, we need to check their decimal representations.

a. 24/60 = 2/5 = 0.4 (terminating decimal, not repeating)

b. 30/64 = 15/32 = 0.46875 (terminating decimal, not repeating)

c. 29/50 = 0.58 (terminating decimal, not repeating)

d. 35/60 = 7/12 = 0.583333... (repeating decimal, as 3 repeats infinitely)

Among the options, only option d (35/60) is equivalent to a repeating decimal.

The repeating decimal representation is 0.583333... where the digit 3 repeats indefinitely.

This can be represented as 0.58(3).

The correct answer is option (d).

Rejecting the null thesis means that;

There's sufficient substantiation to support the claim that the mean is lesser than 32 long hauls per gallon.

For thesis testing, the first thing to define is the null and indispensable thesis.

In thesis testing, especially one comparing two sets of data, the null thesis plays the devil's advocate and generally takes the form of the contrary of the proposition to be tested. It generally contains the signs = , ≤ and ≥ depending on the directions of the test. It generally maintains that, with arbitrary chance responsible for the outgrowth or results of any experimental study/ thesis testing, its statement is true.

The indispensable thesis generally confirms the proposition being tested by the experimental setup. It generally contains the signs ≠,< and> depending on the directions of the test. It generally maintains that significant factors other than arbitrary chance, affect the outgrowth or results of the experimental study/ thesis testing and affect in its own statement.

For this question, Carter Motor Company claims that its new hydrofoil, the Libra, will total better than 32 long hauls per gallon in the megacity. And since this is talking distance covered per gallon of energy, better means that the new hydrofoil will total further than 32 long hauls per gallon.

So, the null thesis negating this claim would be that there is not significant substantiation to conclude that the normal of the new hydrofoil will be more or lesser than 32 long hauls per gallon.

That is, the new normal will be lower than or equal to 32 long hauls per hour.

And the indispensable thesis will confirm the claim that there's significant substantiation to conclude that the normal of the new hydrofoil will be more or lesser than 32 long hauls per gallon.

Mathematically,

The null thesis is represented as

H ₀ μ ≤ 32 long hauls per gallon

The indispensable thesis is given as

Hₐ μ> 32 long hauls per gallon

So, after the thesis test has been conducted, rejecting the null thesis means accepting the indispensable thesis and its statement that there's significant substantiation to conclude that the normal of the new hydrofoil will be more or lesser than 32 long hauls per gallon.

Answer:

A. The function is always decreasing

Step-by-step explanation:

we read a graph from left to right, so we can always compare the increase/decrease of a function by seeing how an x value compares with an x value to the left

(I am aware that this paragraph is really confusing)

we can see that as x increases, from -∞ to 0,

y decreases in correspondence

and that as x increases, from 0 to ∞,

y decreases in correspondence also

So, even though the graph doesn't quite look like it, when x < 0; the function decreases, when x > 0; function decreases--so the function is always decreasing

The longest possible altitude of the third altitude (if it is a positive integer) is 83.

According to statement

Let h is the length of third altitude

Let a, b, and c be the sides corresponding to the altitudes of length 12, 14, and h.

From Area of triangle

A = 1/2*B*H

Substitute the values in it

A = 1/2*a*12

a = 2A / 12 -(1)

Then

A = 1/2*b*14

b = 2A / 14 -(2)

Then

A = 1/2*c*h

c = 2A / h -(3)

Now, we will use the triangle inequalities:

2A/12 < 2A/14 + 2A/h

Solve it and get

h<84

2A/14 < 2A/12 + 2A/h

Solve it and get

h > -84

2A/h < 2A/12 + 2A/14

Solve it and get

h > 6.46

From all the three inequalities we get:

6.46<h<84

So, the longest possible altitude of the third altitude (if it is a positive integer) is 83.

Answer: f^-1(1) + f(-14) = 20, f^-1(-2) = 10

Step-by-step explanation:

When finding the inverse through a table of functions, we are doing the opposite of a function. For example:

If f(9) = 1, then, let me ask you, what is f^-1(1)? Well, that's just 9! You're basically doing the opposite.

An inverse through a table of functions is basically you trying to figure out what x-value did you input to get the f(x) value. A regular function is you trying to figure out what f(x) value did you get by inputting an x-value.

So, the inverse of f(1) is 9, and the regular function of -14 is equal to 11. We then add. 11+9 = 20.

The inverse of -2, like I said before, is you trying to find out the x value you put to get -2. Well looking at the table, it seems x was 10. Thus the inverse of -2 is 10.
