Step-by-step explanation:
Solving an inequality is a lot like solving an equation. Just pretend the inequality symbol is an equal sign!
(also i wont be using the _ or equal to symbol because I'm too lazy, so you'll get >_ or <_ for those, sorry)

Quadrilateral ABCD is a parallelogram with < BCA= 50 , < DCA=60, find value of
Answer:
[tex]ADC = 70[/tex]
Step-by-step explanation:
Given
[tex]BCA = 50[/tex]
[tex]DCA = 60[/tex]
See attachment for parallelogram and complete question
Required
Find ADC
From the attachment:
[tex]BCD = BCA + DCA[/tex]
[tex]BCD = 50+60[/tex]
[tex]BCD = 110[/tex]
Adjacent angles add up to 180.
So:
[tex]ADC + BCD = 180[/tex]
[tex]ADC = 180-BCD[/tex]
[tex]ADC = 180-110[/tex]
[tex]ADC = 70[/tex]

Solve the equation square root of the quantity x plus 3 plus 4 equals 5 for the variable. Show each step of your solution process
Answer:
x=-2
Step-by-step explanation:
[tex]\sqrt{x+3}+4=5[/tex]
subtract 4 from each side
[tex]\sqrt{x+3} +4-4=5-4[/tex]
square both sides
[tex]\sqrt{x+3}^2=1^2[/tex]
so we have
[tex]x+3=1[/tex]
subtract 3 from each side
[tex]x+3-3=1-3[/tex]
so our answer is [tex]x=-2[/tex]

How much force is needed to stop a 1,400 kg truck pulling up to a stop light if
the truck took 4 seconds to stop and was moving at 36 m/s? If you know the answer please include the equation, it would really help me out, thank you! This is not math is is science btw.
Hi there!
[tex]\large\boxed{-12,600 N}[/tex]
Recall that the equation to calculate force is:
F = m · a where m = mass, a = acceleration, and F = net force.
Since we are given the velocity, and time needed to stop, we can calculate the acceleration using the following kinematic equation:
vf = vi + at
The initial velocity is 36 m/s and the final velocity is 0 m/s, therefore:
0 = 36 + at
Move 36 to the other side and plug in the given time:
-36 = 4a
Divide both sides by -4 to find a:
-36/4 = a
a = -9 m/s².
Since the acceleration is -9 m/s² and the mass is 1400 kg, use the above force equation to solve:
F = -9 × 1400 = -12600 N. (negative refers to the force working in the opposite direction of the car's travel. If simply needing the magnitude of the force, it would be 12600 N)

If n = 5, which of the following is not equivalent to 24?
Answer:
there is no picture?
Step-by-step explanation:
solve for 26 - 4s = 9s.
26-4s=9s
⇔26=9s+4s
⇔26=13s
⇔s=2
Answer:
s = 2
Step-by-step explanation:
26 - 4s = 9s
add 4s to 4s and 9s
that equals 13
26/13 = 13s/13
s = 2

Can someone please help me? I am trying to help my son. Here is the problem:
Catherine is hanging a string of lights 40 feet long around the three sides(two on the width and one on the length) of her rectangle patio, which is adjacent to her house. The length of her patio, the side of the house, is eight feet shorter than six times the width. Find the length and the width of the patio.
Thanks everyone!!
Answer:
Step-by-step explanation:
x = width
6x - 8 = length
2x + 6x - 8 = 40
8x = 48
width = 6 feet
length = 28 feet

Answer:
The vertex is at [tex](0, -9)[/tex]
The axis of symmetry [tex]x = 0[/tex]
Step-by-step explanation:
Note: You can answer all the questions looking at the graph
We have the function [tex]f: \mathbb{R} \rightarrow\mathbb{R}[/tex](I am assuming this) such that [tex]f(x) = y = (x-3)(x+3)[/tex]
We note that
[tex](x-3)(x+3) = x^2-9[/tex] once we have a difference of squares
Therefore, we have a quadratic function.
So
[tex]y = x^2-9[/tex]
The vertex [tex](h, k)[/tex] is
[tex]h = \dfrac{-b}{2a} = \dfrac{-0}{2 \cdot 1} = 0[/tex]
[tex]k= h^2 - 9 = 0^2 - 9 =-9[/tex]
Therefore, the vertex is at [tex](0, -9)[/tex]
As we know the vertex, we conclude that the axis of symmetry [tex]x = 0[/tex]
The x-intercepts occur at [tex]y = 0[/tex]
[tex]y = (x-3)(x+3) \implies x = -3, x=3[/tex]
So, the left x-intercept is [tex](-3, 0)[/tex] and the right x-intercept is [tex](3, 0)[/tex]
As I stated in the beginning, the domain is the set of all real numbers. Precisely,
[tex]Dom(f) = \mathbb{R} = (-\infty, \infty)[/tex]
Once, we know the vertex, we also conclude that the Range is
[tex]Ran(f)= [-9,\infty)[/tex]
Greater than or equal to -9

Answer: 5/12
Step-by-step explanation:
Answer:
5/12
Step-by-step explanation:
We are going to change both number so they have the same denominators.
1/4x3/3= 3/12
2/3x4/4=8/12
Once we changed the number we are going to subtract the numbers.
8/12-3/12=5/12
We can't simplify 5/12 so the answer is 5/12.

Step-by-step explanation:
thirty percent of all seventh graders own a bracelet. explain whether the sample closely estimates the percentage of seventh graders who own a bracelet.
30 seventh graders, 3 own a bracelet
The sample of 3 seventh graders who own a bracelet out of 30 seventh graders does not closely estimate the thirty percent of all seventh graders owning bracelets.
What is a percentage?Percentages are fractions where the denominator is 100.
We have,
Number of seven grade students = 30
Number of students who own a bracelet = 3
The percentage of seven grade student who owns a bracelet:
= (3 / 30) x 100
= (1/10) x 100
= 10 %
This means that 10% of seven grade student owns a bracelet.
Thus, the sample does not closely estimate the percentage of seventh graders who owns bracelets.

(40 POINTS!!!!) find FD
Answer:
FD = 25.94
Step-by-step explanation:
13x - 16 = 4x + 11 (Tangents drawn from an external point are equal)
13x - 4x = 11 + 16
9x = 27
x = 3
substituting x in 4x + 11,
4(3) + 11
12 + 11

ΔFED is a right triangle,
FD² = FE² + DE²
FD² = 12² + 23²
FD² = 144 + 529
FD² = 673
FD = 25.94
Answer:
FD= +-25.94
Step-by-step explanation:
EF=CF=r(radius)=12
we know,
FD^2=EF^2+ED^2 ......(1)
and
FD^2=CF^2+CD^2 ......(2)
We Know,
area of triangle, a= 1/2xbasexHeight
a=1/2xEFxED .......(3)
and
a=1/2xCFxCD .....(4)
from equation 3 and 4
1/2xEFxED=1/2xCFxCD
=> 1/2x12xED=1/2x12xCD
=>ED=CD
=>13x-16=4x+11
13x-4x=16+11
9x=27
x=3
so
FD^2=EF^2+(ED)^2
FD^2=(12)^2+(4x3+11)^2
=>FD^2=144+529
=>FD^2=673
FD=+-25.94

[tex]P = (\frac{1}{2}, \frac{\sqrt 3}{2})[/tex]
Answer:
[tex]Rate = 0.935042^\circ /cm[/tex]
Step-by-step explanation:
Given
[tex]P = (\frac{1}{2}, \frac{\sqrt 3}{2})[/tex]
[tex]T(x,y) =x\sin2y[/tex]
[tex]r = 1m[/tex]
[tex]v = 2m/s[/tex]
Express the given point P as a unit tangent vector:
[tex]P = (\frac{1}{2}, \frac{\sqrt 3}{2})[/tex]
[tex]u = \frac{\sqrt 3}{2}i - \frac{1}{2}j[/tex]
Next, find the gradient of P and T using: [tex]\triangle T = \nabla T * u[/tex]
Where
[tex]\nabla T|_{(\frac{1}{2}, \frac{\sqrt 3}{2})} = (sin \sqrt 3)i + (cos \sqrt 3)j[/tex]
So: the gradient becomes:
[tex]\triangle T = \nabla T * u[/tex]
[tex]\triangle T = [(sin \sqrt 3)i + (cos \sqrt 3)j] * [\frac{\sqrt 3}{2}i - \frac{1}{2}j][/tex]
By vector multiplication, we have:
[tex]\triangle T = (sin \sqrt 3)* \frac{\sqrt 3}{2} - (cos \sqrt 3) \frac{1}{2}[/tex]
[tex]\triangle T = 0.9870 * 0.8660 - (-0.1606 * 0.5)[/tex]
[tex]\triangle T = 0.9870 * 0.8660 +0.1606 * 0.5[/tex]
[tex]\triangle T = 0.935042[/tex]
Hence, the rate is:
[tex]Rate = \triangle T = 0.935042^\circ /cm[/tex]
