Answer:
14.90cm [a]
Step-by-step explanation:
To find x, we will apply " sine rule"
that is, [tex]sin[/tex]A/a=[tex]sin[/tex]B/b
here a= x A=90° B=70°anb b =14cm
so we input the values we have
1/x =0.94/14
cross multiply,
0.94x = 14
x = 14/0.94
=14.90cm

In ΔIJK, the measure of ∠K=90°, IJ = 8.6 feet, and KI = 4.5 feet. Find the measure of ∠I to the nearest tenth of a degree.
Answers
Answer:
m∠I = 58.4°
Step-by-step explanation:
cos = adjacent side/hypotenuse
It is always helpful to have a picture. In your case KI is adjacent to ∠I and IJ is the hypotenuse.
So cos I = KI/IJ = 4.5/8.6
arccos (4.5/8.6) = m∠I
m∠I = 58.4°
It is necessary for you to memorize the definitions of the trig functions in order to do these types of problems. OK?

Answers
Answer:
y = -1/20(x + 3)²Step-by-step explanation:
Consider the parent function:
y = x²The graph of the function open up and the vertex is at the origin, the point (0, 0)
Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:
y = -x²The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:
y = -(x + 3)²Since all the options have 1/20 as a coefficient, our function is:
y = -1/20(x + 3)²This is option B

Answer:
[tex]y=-\frac{1}{9}(x-2)^2-3[/tex]
Step-by-step explanation:
When a quadratic equation is in the form [tex]y=a(x-h)^2+k[/tex] (vertex form):
The x-coordinate can be found by identifying which value makes [tex](x-h)^2[/tex] equal 0The y-coordinate can be found by identifying the k value (y=k)Therefore, if the vertex of the function is at (2,-3), h needs to be 2 for [tex](x-h)^2[/tex] to equal 0 and k needs to be -3. The only equation that displays this is G:
[tex]y=-\frac{1}{9}(x-2)^2-3[/tex]

A painter uses 2 1/2 cans of paint 1/4 of a room. How much of a room could he paint with 1 can of paint?
Answers
Answer:
1/10
Step-by-step explanation:
First, convert your numbers to decimals.
2.5 cans of paint cover 0.25 area of a room.
Equation:
2.5=0.25
If you divide 2.5 by 5, you'll get 0.5.
But what you do to one side, you do it to the other.
0.25÷5= 0.05
So now you have your new equation
0.5=0.05
since you want 1 can of paint, multiply it by 2.
1= 0.1
convert it back to fraction: 1/10

A bag contains 6 red marbles, 4 blue marbles and 7 green marbles. If three marbles are drawn out of the bag, what is the probability, , that all three marbles drawn will be green?
Answers
Answer:
Step-by-step explanation:
Not large
Total number of marbles = 4 + 7 + 6 = 17
Number of green marbles = 7
Probability of first marble being green = 7/17
Probability of the second marble being green = 6/16
Probability of the third marble being green = 5/15
Probability (3 green) = 7 / 17 * 6/16 * 5/15 = 210 / 4080 = 0.05147

Input Parameters & Values:
Total number of alphabets (n) & subsets (n1, n2, . . nk) in the word "MATHEMATICS"
n = 11
Subsets : M = 2; A = 2; T = 2; H = 1; E = 1; I = 1; C = 1; S = 1;
n1(M) = 2, n2(A) = 2, n3(T) = 2, n4(H) = 1, n5(E) = 1, n6(I) = 1, n7(C) = 1, n8(S) = 1

A circle with center O is shown. Create the equation for the circle.
Answers
Answer:
(5 - 1)^2 + (1 - 1)^2 = 4^2
Step-by-step explanation:
Circle equation: ( x - h )^2 + ( y - k )^2 = r^2
(h,K) is the coordinate of the center.
Center: (1,1)
(x,y) choose a point that could be the radius. (I choose the one on the top left side).
Point: (5,1)
Diameter: 8
Radius: 4
Plug in:
( x - h )^2 + ( y - k )^2 = r^2
(5 - 1)^2 + (1 - 1)^2 = 4^2 (or 16)
Solve to see if it's true,
(5 - 1)^2 + (1 - 1)^2 = 4^2 (or 16)
4^2 + 0^2 = 4^2
16 = 16 (This is true, therefore, the equation is correct).
Answer:(x-1)^2 + (y-1)^2=16

Any Questions?
which angles are complementary to eachother
Answers
Answer:
1 and 5 are complementary angles
Step-by-step explanation:
A complementary angle is either of two angles whose sum is 90, meaning two opposite angles that add up to 90 degrees.
If you look at angle 3, you see that it is a right angle which is 90 degrees already so any answer containing 3 and another angle is incorrect.
Why 1 and 5 is the correct answer:
the angles 1 and 2 are right next to 3 which is a 90-degree angle, meaning that 1 and 2 add up to 90. angle 5 is opposite of 2 which means that angle 5 and 2 are equal.
So the 1 and 5 would add up to 90, making it the right answer.
Hope this helps you :)
