what the slope of(-1,8) (8,-4)
Answer:
-4/3
Step-by-step explanation:
I think :\
I like ice cream :D
Answer:
-4/3
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -4-8)/(8 - -1)
= ( -4-8)/(8+1)
= -12/9
= -4/3
The bottom of a ladder leaning against a wall is 1.5 m from the bottom of the wall. The ladder is 5.5 m long. Find how high the top of the ladder is above the ground, correct to one decimal place.
A. 5.8 m
B. 5.7 m
C. 5.2 m
D. 5.3 m
Answer: D. 5.3 m
Step-by-step explanation:
The ladder leaning against the wall causes it to forma right angle.
The right angle has two sides , which is the two legs, and the hypotenuse.
Using the formula a^2 + b^2 = c^2 , a and b are the two legs and c is the hypotenuse. In this case, a will be the wall, b will be 1.5 m and the ladder which is 5.5 m will be the hypotenuse.
Input the values for a and c to sole for b using the formula.
1.5^2 + b^2 = 5.5^2
2.25 + b^2 = 30.25
-2.25 -2.25
b^2 = 28
b = [tex]\sqrt{28}[/tex]
b = 5.2915 rounded to one decimal place is the same as rounding it to the nearest tenth, and 5.29 rounded to the nearest tenth is 5.3.
Height of top of ladder above the ground that is resting on the wall, correct to one decimal place is 5.3 m
hence option D is correct.
According to Pythagoras theorem
In a right triangle
[tex]\rm H^2 = P^2 + B^2[/tex]
[tex]\rm P = \sqrt {H^2 - B^2 }.........(1)\\where \\H = Hypotenuse \; of \; right\; triangle\\B = Base\; of \; the \; right\; triangle \\P = Perpendicular \; of \; the\; right\; triangle[/tex]
In the given situation the the ladder forms the right triangle with the wall
Length of the ladder = 5.5 m
Length of the base of ladder from the wall = 1.5 m
Let K be the height of top of ladder above the ground that is resting on the wall.
Hence from equation (1) we can write
[tex]\rm K = \sqrt{5.5^2 - 1.5^2} = \sqrt{28} = 5.291 \approx \bold{5.3}[/tex] m
Height of top of ladder above the ground that is resting on the wall, correct to one decimal place is 5.3 m
hence option D is correct.

-1/3-(-3/5)=
reduce to the simplest form.
The simplest form after solving the given expression, -1/3-(-3/5), is
According to the question,
We have the following expression:
-1/3 -(-3/5)
We know that when a number or a sign is in bracket then it means that it should be multiplied with the numbers or sign outside of the bracket.
We also know that multiplication of two negative numbers gives us the positive result.
-1/3 + 3/5
Now, we change the order of fractions without changing their signs.
3/5 - 1/3
Now, we will make the denominator same by taking least common factor of 5 and 3 (which is 15) and we will subtract the fraction:
(3*3 - 1*5)/15
(9-5)/15
4/15
Now, this fraction can not be divided by the same number in numerator and denominator. So, this is the simplest form.
Hence, the simplest form after solving the expression is 4/15.

What is the image of (7,8) after a reflection over the line y = –x
Answer:
(-7. -8) Just flip the signs.
Answer:
[tex]\boxed {\boxed {\sf (-8,-7)}}[/tex]
Step-by-step explanation:
When a point is reflected over y=-x, the following change occurs:
[tex](x,y)[/tex] ⇒ [tex](-y, -x)[/tex]
We are given the point (7,8).
Essentially, we change the signs for both coordinates, then flip the x-coordinate and y-coordinate.
1. Change the signs
[tex](7,8)[/tex] ⇒ [tex](-7,-8)[/tex]
2. Flip the x and y coordinates
[tex](-7,-8)[/tex] ⇒ [tex](-8,-7)[/tex]
So the image of (7,8) after a reflection over y=-x is (-8,-7)

What is the value of tan A?
8/17
15/8
8/15
15/17
Answer:
B) 15/8
Step-by-step explanation:
Use the SOH-CAH-TOA acronym:
• SOH: Sin(θ) = Opposite / Hypotenuse
• CAH: Cos(θ) = Adjacent / Hypotenuse
• TOA: Tan(θ) = Opposite / Adjacent
Tangent of A would be "opposite" over "adjacent". The side of the triangle opposite angle A would be 15, and the side adjacent to angle A would be 8 -- the value of tan(A) is 15/8.
Tan(A) cannot be 15/7, because 7 is the hypotenuse. Remember that the hypotenuse of a right triangle is the side opposite the 90° angle -- here, angle B is the 90° angle.
