Answer: g(f(4))=9

Step-by-step explanation:

To find g(f(4)), you first find f(4). Then, you plug it into g(x).

f(4)=4-7 [subtract]

f(4)=-3

Now, we know f(4) into g(x).

g(f(4))=(-3)² [exponent]

g(f(4))=9

Now, we know that g(f(4))=9.

The equation Y equals 4/10 X describes the number of kilometers y that a van travels in x minutes. What is the constant speed of

Mekhanik [1.2K]

Answer:

$\frac{4}{10}=0.4$ kilometers per hour.

Step-by-step explanation:

We have been given an $y=\frac{4}{10}x$ , which describes the number of kilometers y that a van travels in x minutes. We are asked to to find the constant speed of the van in terms of hours.

We can see that van travel $\frac{4}{10}x$ kilometers in x hours. To find the constant speed of van, we will substitute $x=1$ in our given equation as:

$y=\frac{4}{10}(1)$

$y=\frac{4}{10}$

Since van travels $\frac{4}{10}$ kilometers in one hour, therefore, constant speed of van is $\frac{4}{10}$ kilometer per hour or $0.4$ kilometers per hour.

Lisa [10]

Answer: 5(√3-1) unit.

Step-by-step explanation:

Since, By the below diagram,

For triangle BDC,

We can write,

$tan 30^{\circ}=\frac{BC}{DC}$

⇒ $\frac{1}{\sqrt{3}}=\frac{BC}{5\sqrt{3}}}$

⇒ $\sqrt{3}=\frac{5\sqrt{3}}{BC}$

⇒ $BC=\frac{5\sqrt{3} }{\sqrt{3} }$

⇒ $BC=5\text{ unit}$

Now, In triangle ADC,

$tan45^{\circ}=\frac{AC}{DC}$

⇒ $1=\frac{AB+BC}{DC}$

⇒ $1=\frac{DC}{AB+BC}$

⇒ $1=\frac{5\sqrt{3}}{AB+5}$

⇒ $AB+5=5\sqrt{3}$

⇒ $AB=5\sqrt{3}-5=5(\sqrt{3}-1)\text{ unit}$

A spinner is divided into 12 equal sections numbered 1-12. What is the probability of landing on a section with a number that is

denis-greek [22]

Answer:

4/12

Step-by-step explanation:

There is a 1 in 12 chance of any number being spun on the wheel. Because there are 4 numbers less than 5, there is a 4 in 12 chance of one of those numbers being spun.
