,

and

,

m

∠

P

=

113

∘

.

Explanation:

By what is given,

m

∠

M

+

m

∠

N

=

90

∘

...

(

1

)

, and,

m

∠

N

+

m

∠

P

=

180

∘

...

.

(

2

)

Since,

m

∠

M

=

23

∘

, by (1), we get,

m

∠

N

=

90

∘

−

23

∘

=

67

∘

.

Using this in

(

2

)

, we get,

m

∠

P

=

180

∘

−

67

∘

=

113

Which of the following is the graph of y=sqr root -x-3

Elan Coil [88]

Answer:

The graph in the attached figure

see the explanation

Step-by-step explanation:

we have

$y=\sqrt{-x-3}$

we know that

The radicand must be greater than or equal to zero

so

$(-x-3)\geq 0$

solve for x

Adds 3 both sides

$-x\geq 0+3$

$-x\geq 3$

Multiply by -1 both sides

Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$x\leq -3$

so

The domain of the function is the interval (-∞,-3]

For x=-3 ---> the value of y=0

The range is the interval {0,∞)

therefore

The graph in the attached figure

The ratio of doves to parrots in a cage is 1 to 2. If there are 6 doves and parrots altogether then how many parrots are there?

Mama L [17]

There would be 2 doves and 4 parrots.

2 + 4 = the 6 in total, and the ratio between doves (2) and parrots (4) is 1 to 2 because the ratio of 2 to 4 is equal to 1 to 2.

A rectangle has an area of 24x^3 and a length of 4x^2 meters. what is the width of the rectangle

lys-0071 [83]

Answer:

6x

Step-by-step explanation:

The area is given by the formula ...

A = LW

Fill in the given values and solve for width.

24x^3 = (4x^2)W

W = (24x^3)/(4x^2) = 6x

The width of the rectangle is 6x.
