We are given a right triangle that has angles of 45°-45°-90°. This would indicate that the triangle is an isosceles type. We can use some trigonemetric functions to solve for the other legs. We do as follows:

sin 45 = p / 10

p = 5√2

cos 45 = q /10

q = 5√2

Write an equation of the line that passes through the given points (7,9),m =4

Alla [95]

Answer:

$y = 4x - 19$

You should also try solving it yourself to make sure I did not make any mistake.

Step-by-step explanation:

We already know the slope so, so far the equation should look like this.

$y = 4x + b$

Now we just need to insert the point into the equation. So point (7,9) 7 should replace the x and 9 will replace the y. It will look like this:

$9 = 4 \times 7 + b$

when you solve this equation you'll get b

$b = - 19$

So the equation is

$y = 4x - 19$

Pls answer this asap

Answer:

$20.44

Step-by-step explanation:

first solve for the whole thing

10 x 6 = 60

now to the red part

2 x 1.5 = 3

now the blue

r^2 * pi = a

2^2 * 3.14

4 * 3.14 = 12.56

now add red and blue

3 + 12.56 = 15.56

now subtract that sum from the whole

60 - 15.56 = 44.44

now do

44.44 / 10 = 4.444

now see how much it would cost for the grass

4.444 * 4.60 = 20.4424 ≈ 20.44

it would cost $20.44 to get the grass reseeded

What is the domain and range of the graph below in interval notation? If union is needed, use Capital U. If infinity is needed u

elena55 [62]

Answer:

DOMAIN: $(-\infty,1]\cup(2,\infty)$

RANGE: $(-\infty,\infty)$

Step-by-step explanation:

The domain of a graph is the span of x-values covered by the graph, while the range of a graph is the span of y-values covered by the graph.

DOMAIN:

From the graph, we can see that the x-values covers everything to the left of x=1. Then we stop and then continue beginning at x=2 all the way until positive infinity.

However, note that at x=1, the dot is a closed circle while at x=2, the dot is an open circle. Thus, we will include x=1 into our domain but not include x=2 into our domain.

So, our domain is all values greater than or less than 1, and all values greater than 2.

In interval notation, this is:

$(-\infty,1]\cup(2,\infty)$

We use brackets with the 1 because we include it in our domain and we use parentheses with the 2 since we do not.

RANGE:

Looking at the graph, it seems that all y-values are covered. The part of the graph on the left covers all y-values less than or equal to 3, while the part of the graph on the right covers all y-values greater than -1. Thus, all y-values are covered.

Our range is all real numbers.

In interval notation, this is:

$(-\infty,\infty)$
