Answer: D
Step-by-step explanation:
By the cosine rule, [tex]BC=\sqrt{10^{2}+14^{2}-2 \cdot 10 \cdot 14 \cdot \cos 70^{\circ}}[/tex]
Now, we can use the law of sines to get that:
[tex]\frac{\sqrt{10^{2}+14^{2}-2\cdot 10 \cdot 14 \cdot \cos 70^{\circ}}}{\sin 70^{\circ}}=\frac{14}{\sin \angle ABC}[/tex]
Meaning that [tex]\sin \angle ABC =\frac{14\sin 70^{\circ}}{\sqrt{10^{2}+14^{2}-2 \cdot 10 \cdot 14 \cdot \cos 70^{\circ}}}[/tex]
And thus [tex]\angle ABC=\sin^{-1} \left(\frac{14\sin 70^{\circ}}{\sqrt{10^{2}+14^{2}-2 \cdot 10 \cdot 14 \cdot \cos 70^{\circ}}} \right) \approx 68.39^{\circ}[/tex]

if 176 dollars = 100 pound and 1 Pound equals to rupees 119 find what is the dollar for nrs.8925
Answers
Answer:
Answer:
NRs. 8925
Step-by-step explanation:
176 dollars = 100 pounds
132 dollars = ??? pounds
Using cross-multiplication, we get:
176 dollars x ??? pounds = 100 pounds x 132 dollars
??? pounds = (100 pounds x 132 dollars)/ 176 dollars
??? pounds = 75 pounds
Now, 1 pound = NRs. 119
So 75 pounds = NRs. ???
Using cross-multiplication again, we get:
1 pound x NRs. ??? = NRs. 119 x 75 pounds
NRs. ??? = (NRs. 119 x 75 pounds)/1 pound
NRs. ??? = NRs. 8925
So the answer is 8925 Nepali rupees

What is the slope and y-intercept? 20 points!!
Answers
Answer:
Slope = 2
Y-intercept = -4
Step-by-step explanation:
The slope of a function is found by finding the change in the y-values and dividing it in the change in x-values.
The change in y-values is 2 because that is the difference between each given data point. The change in x-values is 1 for the same reason.
The slope would be 2/1 which is just 2.
The y-intercept can be found by setting up the function in slope-intercept form (y=mx+b) and using the given data to solve for b. The point I chose to do this with was (2,0)
y=mx+b
y=2x+b
0=(2*2)+b
0=4+b
b=-4
So the slope is 2 and the y-intercept is -4.

Answer:
45.7 meters
Step-by-step explanation:
15 = 6 + 7y
9 = 7y
y = 1.3
The two lengths are still the same, so you can set the two parts equal to the whole. Now that you have y you can substitute it in and add all the sides together.
3y + 7y + 3y + 6y + 6 +15 = P
3(1.3) + 7(1.3) + 3(1.3) + 6(1.3) + 6 + 15 = P
P = 45.7 meters

Solution:
Note that:
y = -x + 1630 = 2x + ySubstitute the value of y into the equation to find x.
30 = 2x + y=> 30 = 2x - x + 16=> 30 = x + 16=> 30 - 16 = x=> x = 14Substitute the value of x into any equation to obtain the value of y.
30 = 2x + y=> 30 = 2(14) + y=> 30 = 28 + y=> 30 - 28 = y=> y = 2Putting the values in (x,y) form.

Find the solution(s) for x in the equation below. (x + 4)(x - 12) = 0
Answers
Answer:
-4 or 12
Step-by-step explanation:
(x + 4)(x - 12) = 0
so
x + 4 = 0 OR x - 12 = 0
x + 4 = 0 leads x = -4
x - 12 = 0 leads x = 12
Answer:
x = -4 or x = 12
Step-by-step explanation:
(x + 4)(x - 12) = 0 means:
(x + 4) = 0 or (x - 12) = 0
x + 4 = 0
Subtract 4 from both sides:
⇒ x + 4 - 4 = 0 - 4
⇒ x = -4
x - 12 = 0
add 12 to both sides:
⇒ x - 12 + 12 = 0 + 12
⇒ x = 12
Therefore the solutions are x = -4 or x = 12

Provide a detailed description of the given transformation.
Answers
Answer:
Look below.
Step-by-step explanation:
The following shape is being reflected across the y-axis.
To confirm this, we can check the coordinates.
When something is reflected across the y-axis, its points' y-coordinate don't change. Upon evaluation of the given transformation, we can see that the y-coordinate does not change for any point.
Now, we check the x-coordinate. The x-coordinate MUST be the opposite of the original x-coordinate...
-2 --> 2
-4 --> 4
0 --> 0
-4 --> 4
-2 --> 2
All of the x-coordinates are opposites, and the y-coordinates remained the same, therefore this figure is being reflected across the y-axis.

What is inequality?
It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
We are given four number inequalities:
30 > 10
30 < 10
10 > 30
10 < 30
The first number sentence, "30 > 10", is true, since 30 is greater than 10.
The second number sentence, "30 < 10", is false, since 30 is not less than 10.
The third number sentence, "10 > 30", is false, since 10 is not greater than 30.
The fourth number sentence, "10 < 30", is true, since 10 is less than 30.
Therefore,
We would circle the first and fourth number sentences as true, and cross out the second and third number sentences as false.
