Mathematics
1 answer:
svp [43]3 years ago
3 0

Answer:

A

Step-by-step explanation:

Take any two points on the line

(-4,0) and (0,-1) find the slope

slope= y2-y1/x2-x1

=\frac{-1-0}{0-(-4)}=\frac{-1}{0+4}=\frac{-1}{4}

y-y1 = m(x-x1)

y-0=\frac{-1}{4}[x-(-4)]\\\\y=\frac{-1}{4}(x+4)\\\\y=\frac{-1}{4}*x+4*\frac{-1}{4}\\\\y=\frac{-1}{4}x-1

A 20 foot ladder is leaning against the side of a building. The bottom of the ladder is 4 feet from the wall. How many feet abov
Semenov [28]
It form a right triangle
legnth of ladder is hypotonuse
bottom of ladder from wall distance is one leg
distance up wall is other leg
a^2+b^2=c^2
c=hypotonuse and a and b are legs

4^2+b^2=20^2
16+b^2=400
minus 16 both sides
b^2=384
sqrt both sides
b=8√6 ft
aprox
b=19.59ft from ground

During a baseball game, a food stand sells popcorn for $2.50 and hotdogs for $3 each. If at the end of the game, the stand made
nasty-shy [4]
Let
x-------> bags of <span>popcorn
</span>y-------> bags of hotdogs

we know that
2.50x+3y=200-------> equation 1
x=2y--------> equation 2

substitute 2 in 1

2.50*[2y]+3y=200--------> 5y+3y=200------> 8y=200-----> y=200/8
y=25
x=2y-----> x=2*25-----> x=50

the answer is
50 bags of popcorn
25 bags of hotdogs<span />

S and Tare mutually<br> exclusive events. Find P(sort)<br> P(S) = 12% P(T) =27%
mario62 [17]

The value of the probability P(S or T) is 39%

<h3>How to determine the probability?</h3>

The probability values are given as:

P(S) = 12% P(T) =27%

For mutually exclusive events,

P(S or T) = P(S) + P(T)

This gives

P(S or T) = 12% + 27%

Evaluate the sum

P(S or T) = 39%

Hence, the value of the probability P(S or T) is 39%

Find the distance CD rounded to the nearest tenth
motikmotik

Answer:

CD ≈ 15.0

Step-by-step explanation:

calculate CD using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = C (7, - 4) and (x₂, y₂ ) = D (- 8, - 5)

CD = \sqrt{(-8-7)^2+(-5-(-4))^2}

     = \sqrt{-15)^2+(-5+4)^2}

     = \sqrt{225+(-1)^2}

     = \sqrt{225+1}

     = \sqrt{226}

     ≈ 15.0 ( to the nearest tenth )
