Roll 2 six-sided number cubez how many possibilties contain only even numbers
Answer:
1/2 of the possibilities are even number
Step-by-step explanation:
Add all of the sides together, you get 12, count on even numbers until you get to 12. 2,4,6,8,10,12. that's six numbers which is half of 12. so half of the possibilities are even.
The top of a ladder slides down a vertical wall at a rate of 2 feet per second. At the moment when the bottom of the ladder is 4 feet from the wall, it slides away from the wall at a rate of 3 feet per second. How long is the ladder
Answer:
The length of the ladder is 7.21 feet
Step-by-step explanation:
Let
y = Height of the wall
x = Distance between the wall and the ladder (bottom)
L = Length of the ladder
So, the given parameters are:
[tex]\frac{dy}{dt} = -2ft/s[/tex]
When [tex]x = 4; \frac{dx}{dt} = 3ft/s[/tex]
The ladder, the wall and the ground forms a right-angled triangle where the hypotenuse is the length of the ladder; So:
[tex]L^2 = x^2 + y^2[/tex]
Differentiate with respect to time
[tex]2L\frac{dL}{dt} = 2x\frac{dx}{dt} + 2y\frac{dy}{dt}[/tex]
The length of the ladder does not change with time. So:
[tex]2L*0 = 2x\frac{dx}{dt} + 2y\frac{dy}{dt}[/tex]
[tex]0 = 2x\frac{dx}{dt} + 2y\frac{dy}{dt}[/tex]
Rewrite as:
[tex]2x\frac{dx}{dt} =- 2y\frac{dy}{dt}[/tex]
Divide both sides by 2
[tex]x\frac{dx}{dt} =- y\frac{dy}{dt}[/tex]
Recall that:
[tex]\frac{dy}{dt} = -2ft/s[/tex] and [tex]x = 4; \frac{dx}{dt} = 3ft/s[/tex]
So:
[tex]4 * 3 = -y * -2[/tex]
[tex]12 = 2y[/tex]
[tex]6 = y[/tex]
[tex]y = 6[/tex]
Substitute [tex]y = 6[/tex] and [tex]x =4[/tex] in: [tex]L^2 = x^2 + y^2[/tex]
[tex]L^2 =4^2 + 6^2[/tex]
[tex]L^2 =52[/tex]
[tex]L = \sqrt{52[/tex]
[tex]L = 7.21ft[/tex]

which of the following is true about the function below? 1/√x-6
Answer:
Assuming the x-6 is under the square root sign, the value must be greater than 6 because you can not have 0 in the domain. That narrows it down to either B or C but since the denominator can not be anything less than 0, your answers will always be positive so that means the answer is Its domain is (6,∞)
Answer:
Its domain is (6,∞) and its range is (0,∞) your welcome :3

C 4(7 + 3)
D 7(4 + 7)
what is the equation of the line in slope-intercept form?
Answer:
y = 8x
Step-by-step explanation:
Slope intercept form is y = mx + b
y = y coordinate
m = slope, rise over run
x = x coordinate
b = y-intercept, where the line crosses the y-axis.
y = mx + b
y = 80/10x + 0
y = 8x + 0
y = 8x
Answer:
y=-8x

what is 2 X (6+ 2 + 8) -4
Answer:
The correct answer is 32x - 4
Step-by-step explanation:
1) Simplify 6 + 2 to 8.
[tex]2x(8 + 8) - 4[/tex]
2) Simplify 8 + 8 to 16.
[tex]2x \times 16 - 4[/tex]
3) Simplify 2x × 16 to 32x.
[tex]32x - 4[/tex]
Therefor, the answer is 32x - 4.
Solve the inequality:
8+4x≥12
Select one:
x≤1
x≥5
x≥1
x≤5
Answer:
x ≤ 1
Step-by-step explanation:
8 + 4x [tex]\geq[/tex] 12
4x [tex]\geq[/tex] 12 - 8
4x ≥ 4
Dividing both sides by 4 gives;
x ≤ 1

Answer:
around 13.18
Step-by-step explanation:
the middle square is 2*2 = 4
the triangle then is 2^2 + 6^2 = 40 -> sqrt40 = 6.325
and then 2^2 + 2^2 = 8 -> sqrt8 = 2.828
4+6.325+2.828 = 13.18
Answer:
8
Step-by-step explanation:
because since it is a square all sides are the same length you can either add 2+2+2+2 or you can do 2x2=4x2 which equals 8
