You pick a card at random what is p(3 or even)

Katarina [22]

Answer:

"?" = 3

Step-by-step explanation:

The answer can be gotten by subtracting 4 from 7. The 4 is the exponent in (4a^4b), and the 7 is the exponent in 16a^7b. So:

7 - 4 = 3

Therefore, the "?" = 3

Hope this helps :)

Today, Isaac needs to walk his dog, water the garden, and feed his fish. DDD is the number of minutes it takes to walk his dog,

yarga [219]

Answer:

The total Minutes of the Inside tasks.-F (Fish)
The total Minutes of the Outside tasks.-G+D (Garden and Dog)
The total Minutes of the tasks involving animals.-D+F (Dog and fish)
The total Minutes of the tasks not involving animals.-G (Garden

Step-by-step explanation:

D is the number of minutes it takes to walk his dog

G is the number of minutes it takes to water the garden

F is the number of minutes it takes to feed his fish.

We are required to match these situations to their respective expressions:

Situation

The total Minutes of the Inside tasks.
The total Minutes of the Outside tasks.
The total Minutes of the tasks involving animals.
The total Minutes of the tasks not involving animals.

Expression

D+F
G+D
G
F

Match:

The total Minutes of the Inside tasks.-F (Fish)
The total Minutes of the Outside tasks.-G+D (Garden and Dog)
The total Minutes of the tasks involving animals.-D+F (Dog and fish)
The total Minutes of the tasks not involving animals.-G (Garden)

What are the zeros of the function f(x) = x2 + 8x + 4, expressed in simplest radical form?

Katyanochek1 [597]

Answer:

Step-by-step explanation:

assuming it is $x^{2} +8x+4$

Using Quadratic formular -

a - 1

b - 8

c - 4

$x= \frac{ -8 -,+ \sqrt{(8^2) - 4 (1)(4)}}{2(1)} \\\\$

$x = \frac{-8 +,- \sqrt{48} }{2}\\\\$

$x = \frac{-8+,- 4\sqrt{3} }{2}$

$x = {-4+,- 2\sqrt{3} }$

Please help!! law of sines and cosines related

pickupchik [31]

Answer:

as below

Step-by-step explanation:

to find the height of the pole recall the relationship of sin cos and tan to the triangle with this helpful mnemonic SOH CAH TOA

Sin = Opp / Hyp

Cos = Adj / Hyp

Tan = Opp / Adj

we will need to solve two triangles and subtract them.

one is the 15° one of the slope of the road and the other is the 57° one that is the angle of the sun. sooooo,

lets solve the 15° one first. We are told that the adj side is 75'

since we know the angle and the adj side and we want to find the Opp side let's use Tan b/c it has all of those in it :)

Tan(15) = Opp / 75

75*Tan(15) = Opp ( I'll put my calculator to work for this )

20.096 = Opp

that's the height of the road to the bottom of the flag pole along that flag pole axis into the ground

next lets solve the 57° triangle in the exact same way

Tan(57) =Opp / 75

75*Tan(57) = Opp

115.4898 = Opp

the tall triangle is the one that goes all the way into the ground, the small one is the one that is under the ground

so subtract the small one from the big one to find the height of the flag pole above the ground

115.4898-20.096 = 95.3938

so the flag pole is about 95.4 feet tall

:o that's pretty tall :
