Question 4

skelet666 [1.2K]

Answer:

See explanation

Step-by-step explanation:

You forgot to give the coordinates of C.

Note that, the mapping for 90° clockwise rotation around the origin is given by:

$(x,y)\to (-y,x)$

Assuming the coordinates of C were (-6,6), then the coordinates of C after a 90° clockwise rotation

around the origin is (-6,-6)

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.

F(x)=3^2-2and g(x) =4x+2 what is the value of (f+g)(2)

morpeh [17]

Step-by-step explanation:

$f(x) = {3}^{2} - 2 = 9 - 2 = 7 \\ g(x) = 4x + 2 \\ \therefore \: (f + g)(x) = 7 + 4x + 2 \\ \therefore \: (f + g)(x) = 4x + 9 \\ \therefore \: (f + g)(2) = 4 \times 2 + 9 \\ \therefore \: (f + g)(2) = 8 + 9 \\ \red{\boxed{ \bold{ \therefore \: (f + g)(2) = 17}}}$
