Answer:
A bullet fired from a gun has a muzzle velocity of 3510 km per hour how long dies it take to travel 100m
Step-by-step explanation:
Given :
Velocity of bullet = 3510 km/hr
Distance traveled = 100m
Converting distance in meter to kilometer :
(100 / 1000) km = 0.1 km
Recall :
Speed = Distance /time
Time taken = Distance / speed
Therefore,
Time taken = Distance / speed
Time taken = 0.1 km / 3510 km/hr
Time = 2.849 * 10^-5 hour

What is an
equation of the line that passes through the points (-4,-4) and (4, 6)?
Answer:
Step-by-step explanation:
1.) Find the slope
[tex]\frac{y_2-y_1}{x_2-x_1} = \frac{6-(-4)}{4-(-4)}= \frac{6+4}{4+4} = \frac{10}{8}=\frac{5}4}[/tex] = m2.) Use the slope-point form for a line
[tex]y-y_0=m(x-x_0)[/tex]
Pick any point (-4,-4) or (4,6) into [tex]y_0 and x_0\\[/tex]
but your equation is y= 5/4x+1

A house cast 65-foot shadow. A person standing nearby cast 7.2 foot shadow. Their height is 4.8 feet. What is the height of the house?
Answer:
42.43 feets
Step-by-step explanation:
Given :
(Height of house / shadow of house) = (height of person / shadow of person)
(height of house / 65) = (4.8 / 7.2)
Cross multiply
Height of house * 7.2 = 4.7 * 65
Height of house = 305.5 / 7.2
Height of house = 42.43 feets

Find the midpoint of A and B where A has coordinates (-3,-5) and B has coordinates (4,4).
Brainliest if you want :)
Use the midpoint formula,
[tex]\left( \dfrac{x_1+x_2}{2} , \dfrac{y_1+y_2}{2} \right)[/tex]
where x₁ = -3, x₂ = 4, y₁ = -5, and y₂ = 4.
[tex]\left( \dfrac{x_1+x_2}{2} , \dfrac{y_1+y_2}{2} \right) \implies \left( \dfrac{-3+4}{2} , \dfrac{-5+4}{2} \right) = \left(0.5, -0.5\right).[/tex]
So, the midpoint of A and B is (0.5, -0.5). It should be in the first quadrant.

Find the value of x.
Answer:
x = 33
Step-by-step explanation:
x - 12 and 2x + 3 form a right angle , then
x - 12 + 2x + 3 = 90
3x - 9 = 90 ( add 9 to both sides )
3x = 99 ( divide both sides by 3 )
x = 33

Step-by-step explanation:
just took the test
The table shows the balance of two accounts each year for four years. Determine whether each balance is linear or nonlinear. Then predict which account will have a greater balance in Year 3.
Year, t Account A Balance Account B Balance
0 $450 $550
1 $504 $570
2 $564.48 $590
Account A Balance is linear. Account B Balance is nonlinear. Account A will have a greater balance in Year 3.
Account A Balance is nonlinear. Account B Balance is linear. Account A will have a greater balance in Year 3.
Account A Balance is linear. Account B Balance is nonlinear. Account B will have a greater balance in Year 3.
Account A Balance is nonlinear. Account B Balance is linear. Account B will have a greater balance in Year 3.
Account A Balance is nonlinear. Account B Balance is linear. Account A will have a greater balance in Year 3. Then the correct option is B.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
The slope for account A is calculated as,
m = (504 - 450) / (1 - 0) = (564 - 504) / (2 - 1)
54 ≠ 60
Account A is non-linear. The amount after 3 years will be more than $620 ($564 + $60).
The slope for account B is calculated as,
m = (570 - 550) / (1 - 0) = (590 - 570) / (2 - 1)
20 = 20
Account A is linear. The amount after 3 years will be $610 ($590 + $20).

The hypotenuse of a 30 -60 -90 triangle is 13cm. What is the length of the shorter leg?
Answer:
(13/2) cm
Step-by-step explanation:
The hypotenuse here is of length 13 cm. The shorter leg lies opposite to the 30° angle. Recall that the sine function is defined as
opposite side
sin Ф = -----------------------
hypotenuse
which, in this case, works out to:
opposite side
sin 30° = -----------------------
13 cm
and so the length of the opposite side (which is also the "shorter leg") is
shorter leg length = (13 cm)(sin 30°) = (13 cm)(1/2) = (13/2) cm

y= -x +3 and y = x - 1
Answer:
x=2 and y=1
Step-by-step explanation:
Rewrite equations:
y=−x+3;y=x−1
Step: Solve
y=−x+3
Step: Substitute−x+3foryiny=x−1:
y=x−1
−x+3=x−1
−x+3+−x=x−1+−x(Add -x to both sides)
−2x+3=−1
−2x+3+−3=−1+−3(Add -3 to both sides)
−2x=−4−2x−2=−4−2
(Divide both sides by -2)
x=2
Step: Substitute2forxiny=−x+3:
y=−x+3
y=−2+3
y=1(Simplify both sides of the equation)
