Answer:

50 km/h

Step-by-step explanation:

so you traveled total of 350 (km) in 7 (hours) right?, just take 350, divide it by 7, which will give you km/h. (or 50 km/h) and then when you add a direction it like "west" it's no longer a speed it's a velocity.

Displacement given (in metres) = (350 × 1000)m.

Displacement = 350000 metres.

Time = (7× 3600) seconds

Time = 25200 seconds.

Velocity = Displacement / Time

Velocity = 350000 / 25200

Velocity = 13.89m/s

Approximately, Velocity = 14m/s.

B

Step-by-step explanation:

the cube (this is the ³ at the end of the numerator) of

the difference of 5 times the square of y and 7 :

(5y² - 7)

all divided by the square (that is the ² at the end of the denominator) of

2 times y :

(2y)

A would be

((5y)² - 7)³/(2y)²

C would be

Answer:

8,588 people

Step-by-step explanation:

We can represent this exponential decay as [tex]P=10000(0.97)^n[/tex] where [tex]n[/tex] is the number of years later:

[tex]P=10000(0.97)^n\\\\P=10000(0.97)^5\\\\P=10000(0.8587340257)\\\\P=8587.340257\\\\P\approx8588[/tex]

Therefore, the population 5 years later will be 8,588 people

Step-by-step explanation:

Ok so after the first year we expect the population to reach 97% of it's initial population.

So 97% of 10 000 can be written as:

97/100 ×10 000=0.97×10 000=9 700

After the second year we expect the population to drop to 97% of the first year's population

So, it can be said that:

0.97×9700= 9409

Similarly after year 3,

0.97× 9409= 9126.73

Year 4,

0.97× 9126.72= 8852.9281

Year 5,

0.97× 8852.9281=8587 rounded to the nearest number

The new population would be 8587

If a function f(x) has an inverse f ⁻¹(x), then by definition

[tex]f\left(f^{-1}(x)\right) = x[/tex]

Differentiating both sides with respect to x yields

[tex]f'\left(f^{-1}(x)\right) \times \left(f^{-1}\right)'(x) = 1 \implies \left(f^{-1}\right)'(x) = \dfrac1{f'\left(f^{-1}(x)\right)}[/tex]

Now, if f(a) = b and b = f ⁻¹(a), then

[tex]\left(f^{-1}\right)'(a) = \dfrac1{f'\left(f^{-1}(a)\right)} = \dfrac1{f'(b)}[/tex]

Answer:

96 inches

Step-by-step explanation:

Given the following question:

12 inches = 1 foot

To find the answer we simply need to multiply 12 by 8, since every 12 inches are equal to 1 foot and we need to find how many inches are in 8 feet.

[tex]12in=1ft[/tex]
[tex]8\times12=96[/tex]
[tex]=96in[/tex]

8 feet is equal to "96 inches."

Using the z-distribution, as we have the standard deviation for the population, to test the hypothesis, it is found that this is evidence that workers in the large city take longer than 28 minutes to get home from work.

At the null hypothesis, it is tested if the mean time is of 28 minutes, that is:

[tex]H_0: \mu = 28[/tex]

At the alternative hypothesis, it is tested if the mean time is greater than 28 minutes, that is:

[tex]H_1: \mu > 28[/tex].

The test statistic is given by:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

The parameters are:

In this problem, the values of the parameters are given by:

[tex]\overline{x} = 32, \mu = 28, \sigma = 5, n = 10[/tex]

Hence:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{32 - 28}{\frac{5}{\sqrt{10}}}[/tex]

[tex]z = 2.53[/tex]

Considering that we have a right-tailed test, as we are testing if the mean is greater than a value, with a standard significance level of 0.05, the critical value is of [tex]z^\ast = 1.645[/tex].

Since the test statistic is greater than the critical value, it is found that this is evidence that workers in the large city take longer than 28 minutes to get home from work.

Step-by-step explanation:

Given the following questions:

[tex]3\frac{3}{7} \\3\frac{5}{6}[/tex]

To convert mixed numbers into improper fractions we need to multiply the denominators by the whole numbers, and then add that answer to the numerator while of course keeping the denominator the same.

Question one:

Answer:

65 yd

Step-by-step explanation:

The diagonal of a rectangle can be found using

Pythagoras' Theorem  a² + b² = c²

(where a and b are the legs, and c is the hypotenuse of a right triangle)

Given:

⇒ 25² + 60² = c²

⇒ c² = 4225

⇒ c = √4225

⇒ c = 65

Therefore, the length of the diagonal is 65 yd

Answer:

-7

Step-by-step explanation:

first multiply 3 and 4 because PEMDAS

so it now looks like

12 - 9 - x = 10

now minus 12 and 9

3 - x = 10

move x to the other side by adding x to both sides

3 = 10 + x

and move 10 to the other side by subtracting  10 to both sides

3 - 10 = x

x = -7

now check

3*4 - 9 - (-7) = 10 ?

12 - 9 + 7 = 10 ?

3 + 7 = 10 ?

10 = 10

Step-by-step explanation:

[tex]3\cdot \:4+\left(-9\right)-x=10[/tex]
