area of a trapezoid 6 mm 2 mm 4 mm

Answer:

3/4 lb

Step-by-step explanation:

You can use multiplication:

3 × 1/4 lb = 3/1 × 1/4 lb = 3/4 lb

You can also use addition:

1/4 lb + 1/4 lb + 1/4 lb = 3/4 lb

Answer:

900 g

Step-by-step explanation:

let e be extension and w be weight

given e varies directly as w then the equation relating them is

e = kw ← k is the constant of variation

to find k use the condition w = 150 , e = 2.9 , then

2.9 = 150k ( divide both sides by 150 )

[tex]\frac{2.9}{150}[/tex] = k , that is

k = [tex]\frac{29}{1500}[/tex]

e = [tex]\frac{29}{1500}[/tex] w ← equation of variation

when e = 17.4 , then

17.4 = [tex]\frac{29}{1500}[/tex] w ( multiply both sides by 1500 )

26100 = 29w ( divide both sides by 29 )

900 = w

Answer:

24 m/s²

a = 24 m/s²

Answer:

$2.75

Step-by-step explanation:

Since x represents the number of years since 1980 to 2000 that means the ticket prices increase by 0.10 (or 10 cents) each year. This means the base price in 1980 was $2.75. To prove it, we would plug in the correct information into the expression. The number of years since 1980 would be 0 so we would plug in 0 for x. 2.75 + 0.10(0) = $2.75.

The way to identify these tables is through the way that the value of y increases.

A linear table is a table that increases or decreases by a common difference. Check the attachment to see how it increases.

This is the table that the value increases with a common ratio. The y value doubles in this case.

This is a table that has a constant second difference.

Answer:

The X-coordinate is -7

Step-by-step explanation:

We need a acceleration time graph (Attached)

So when t is 0

Find y intercept by observing the point where the line crosses y axis

Now the particle is given moving along x axis means on the x axis

So acceleration remains 0 as on x axis y intercept is 0 always

Using the uniform distribution, it is found that:

a) There is a 0.3333 = 33.33% probability that the friend is between 10 and 20 minutes late.

b) Within 9 minutes.

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The probability of finding a value of at lower than x is:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

The probability of finding a value between c and d is:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

Researching the problem on the internet, it is found that the variable is uniform with a = 0 and b = 30.

Item a:

[tex]P(10 \leq X \leq 20) = \frac{20 - 10}{30 - 0} = 0.3333[/tex]

There is a 0.3333 = 33.33% probability that the friend is between 10 and 20 minutes late.

Item b:

This is x for which P(X < x) = 0.3, hence:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

[tex]0.3 = \frac{x}{30}[/tex]

[tex]x = 9[/tex]

Within 9 minutes.

5)

5x⁴-4x³-3x-4+2x⁴+6x³-2x

7x⁴+2x³-5x-4

Just do the simple addition. Make sure to add like terms. For instance: Add 3x² with 2x² only, not with 3x and 2.

→ 2x² + 3x + 2 + 3x² - 5x - 1

→ 2x² + 3x² + 3x - 5x + 2 - 1

The law of subtraction is to subtract the smaller value from the larger value. But it is not necessary that it is always applicable. Its value can be positive, negative and zero (which varies with the given values).

→ x² - 4 - (12x² + 4x - 6)

There will be no change in sign during addition. But if you're doing subtraction change the signs.

→ x² - 4 - 12x² - 4x + 6 [ Product of (-)(-) is (+) and (+)(-) is (-) ]

→ x² - 12x² - 4x - 4 + 6

→ 6x² + 3x - 4 + x² - 7

→ 6x² + x² + 3x - 4 - 7

→ 7x³ + 4x - 1 + 2x² - 6x + 2

→ 7x³ + 2x² + 4x - 6x - 1 + 2

→ 5x⁴ - 4x³ - 3x - 4 - (-2x⁴ - 6x³ + 2x)

→ 5x⁴ - 4x³ - 3x - 4 + 2x⁴ + 6x³ - 2x

→ 5x⁴ + 2x⁴ - 4x³ + 6x³ - 3x - 2x - 4

Answer:

Angle B measures 116 degrees

Step-by-step explanation:

Because all the angles of a triangle add up to 180 degrees.

28 degrees + 36 degrees = 64 degrees

180 degrees - 64 degrees = 116 degrees

Answer:

116

Step-by-step explanation:

The sum of all the angles in a triangle will equal 180 degrees. SO, to find the missing angle, we have to add the two known angles together and subtract that from 180.

28 + 36 = 64

180 - 64 = 116

Therefore, the measure of the missing angle is 116 degrees.

Answer:

The graph is a function of absolute value.

This means that for each value of f (x) there are two possible values of x.

The absolute value function is:

f (x) = lxl

y = f (x) - 2 shifts the graph 2 units down.

y = f (x + 3) moves the graph 3 units to the right.

Finally:

The function that best fits this graph is:

f (x) = l-x + 3l-2

Step-by-step explanation:

From the graph it is evident that it is the graph of the absolute value of the function i.e. f(x) = |x| and we know that 'Translation' is a transformation that shifts the graph of a function in any direction.

Now, as we can see that the graph is shifted towards the right of the y-axis at point x=3, this means that it is translated by 3 units to the right of y-axis.

Therefore, the function becomes f(x) = |x-3|.

Furthermore, it is also shifted downwards at the point x= -2, this means that it is translated by 2 units downward from the x-axis.

Hence, the new function is f(x) = |x-3| - 2.

The value of the function for the other factors will be -1.41  and - 3.90 respectively.

It is a method for dividing a polynomial into parts, each of which will be multiplied. At this moment, the polynomial's value will be zero.

Given function;

f(x) =2x⁴ - 2x-5

The roots (zeros) are the

x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.

x≈−1.089744,1.40581409

The value of the function for the other factors;

f(x) =2x⁴ - 2x-5

f(−1.089744) = 2(−1.089744)⁴-2(1.089744)-5

f(−1.089744) = -1.41

f(x) =2x⁴ - 2x-5

f(1.40581409) = 2(1.40581409)⁴-2(1.40581409)-5

f(−1.089744) = - 3.90

The value of the function for the other factors will be -1.41 and - 3.90 respectively.
