Determine the constant that should be added to the binomial so that it becomes a perfect square trinomial. Then write and factor the trinomial. x2 + 16x
Answer:
[tex]$64, \ (x+8)^2$[/tex]
Step-by-step explanation:
A perfect square trinomial is defined as an expression that is obtained from squaring a binomial equation. The perfect square trinomial is in the form of [tex]$ax^2+bx+c$[/tex].
The given expression is :
[tex]$x^2+16x$[/tex]
The co-efficient of the x-term in [tex]$x^2+16x$[/tex] is '16'.
So half of the term 16 ,
[tex]$\frac{16}{2} = 8$[/tex]
and [tex]$(8)^2=64$[/tex]
Now add 64 to the expression:
[tex]$x^2+16x+64$[/tex]
Therefore, the perfect square trinomial is
[tex]$(x+8)^2=x^2+16x+64$[/tex]
Bern is flying a kite directly over his friend Frank. Bern lets out string which makes an angle of 28°
with the ground. If the kite is 175 feet above Frank, how far are Bern and Frank?
Help ASAP!!
orayt so 28 degree and 175 feet is about...the fox jumps into the lazy dog and say "c'mon barbie let's go party! ah ah ah yeah"....but i dont know the answer as well so thank you.
Answer:
Approximately [tex]329\; \rm ft[/tex], assuming that the ground between Bern and Frank is level.
Step-by-step explanation:
Refer to the diagram attached.
The kite is right above Frank. Therefore, the imaginary line segment (the dashed line segment in the diagram) would form a right angle with the ground under Frank. Bern, Frank, and the Kite would be the three vertices of a right triangle.
The question states that from the perspective of Bern, the angle of elevation of the kite is [tex]28^\circ[/tex]. In this right triangle, the side opposite to this angle would be the imaginary line segment between Frank and the kite over him. The question states that the length of this imaginary line segment is [tex]175\; \rm ft[/tex].
The question is asking for the length of the line segment between Bern and Frank. In the right triangle pictured in this diagram, that line segment would be the side adjacent to the [tex]28^\circ[/tex] angle.
The cotangent of [tex]28^\circ[/tex] would be the ratio between the length of these two sides:
[tex]\displaystyle \cot (28^\circ) = \frac{\text{adjacent}}{\text{opposite}}[/tex].
[tex]\begin{aligned}\text{adjacent} &= \text{opposite} \cdot \cot(28^\circ) \\ &= (175\; \rm ft) \cdot \cot(28^\circ) \approx 329\; \rm ft\end{aligned}[/tex].

Answer:
Its D.
Step-by-step explanation:
The expanded form of this number 630.052 is (6×100)+(3×10)+(5×1/100)+(2×1/1,000). Option D is correct.
What is the definition of arithmetic operation?Arithmetic is a branch of mathematics that studies numbers and the many operations that may be applied to them. The four basic math operations are addition, subtraction, multiplication, and division.
The expanded form of this number 630.052 is solved by the BODMAS rule ;
630.052= (6×100)+(3×10)+(5×1/100)+(2×1/1,000)
630.052=6×100+3×10+5×0.01+2×0.001
630.052=600+30+0.05+0.002
630.052=630.052
The expanded form of this number 630.052 satisfy the option D.
Hence option D is correct.

Step-by-step explanation:
I don't know what constructions you were taught.
a "similar" triangle is a triangle with exactly the same angles as the other triangle, but the lengths of all sides are stretched or shortened by the same scaling factor f.
by saying 1:2 she means the second triangle should have sides with twice the lengths of the first triangle (f=2).
and the extra challenge - same basic thing. she allows you to pick one of the two triangles as reference. and then you need to draw a third triangle (again with the same angles) with the side lengths extended by the scaling factor f of 4/3.
I would draw the triangles right on top of each other with the same starting corner (let's call it A) for all 3.
we would get the triangles ABC, AMN and AXY.
the points B and C would be then halfway on AM and AN.
and M and N would then a bit before X and Y on AX and AY.
the beauty is, you only need to construct 2 sides of every new triangle down to the new endpoints. the third side is automatically scaled correctly, and you only need to connect these new endpoints.
let's assume you draw a triangle (just very simple) ABC with all side lengths being 3. so, AB=3, AC=3, BC=3.
now you draw AMN by extending AB and AC to a side length of 6 (f=2) creating M and N, and you connect M and N.
and then you can create the third triangle AXY by extending AM and AN by a factor of 4/3 to side lengths of 8 (4/3 × 6 = 8) creating new end points X and Y. and you connect X and Y.
and that is it. all 3 triangles are similar (the same angles), and all sides of a triangle have the same length ratio to the sides of the other triangle(s).
Can u Put 9x + 3y = -9in slope intercept form ?
Answer:
y = - 3x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
9x + 3y = - 9 ( subtract 9x from both sides )
3y = - 9x - 9 ( divide terms by 3 )
y = - 3x - 3 ← in slope- intercept form
if x+2 is a factor of the polynomial: 3x²+kx, then the value is
Answer:
k = 6
Step-by-step explanation:
(x+2) is a factor of 3x²+kx so if we solve (x+2) = 0 that will give us one of the solutions of x for 3x²+kx = 0, and then we can substitute that solution in and find the value of k.
So to find a solution, (x+2) = 0 and therefore x = -2
Now substitute x = -2 into 3x²+kx = 0
so 3(-2)²+k(-2) = 0
12 - 2k = 0
2k = 12
k = 6

Answer:
$ 22.5
Step-by-step explanation:
B(x) = 30.50 - 0.20x
Notice that x defines the number of prints.
For prints = x = 40
B(40) = 30.50 - 0.20(40)
B(40) = 30.50 - 8
B(40) = 22.5
Remaining amount is $22.5
B(x) is defined as at starting you had $30.50 then you kept on spending with a period of 20 cents(= 0.20 dollar). So 30.50 kept on decreasing by 0.20. Each time you spend, you give 0.20.
That's why the function is 30.50 - 0.20x.
Where x is the nunber of times you spend(buying prints)
Diane has pulled 2 green marbles and 10 other marbles from a large bag. What is the experimental
probability that the next marble selected from the bag will be green?
The experimental probability that the next marble selected from the bag will be green is 1/6.
What is the experimental probability?Experimental probability is the probability that an event would happen based on a previously carried out experiment.
The experimental probability that the next marble selected from the bag will be green = total number of green marbles / total number of marbles
2 / ( 2 + 10)
= 2/12

help me pls!! i rlly need it!!
Answer:
3. below
<D = 75°
<E = 37°
<F = 68°
4. below
<G = 50°
<H = 80°
<I = 50°
5. below
<A = 55°
<B = 90°
<C = 35°
Step-by-step explanation:
In a triangle, all angles add up to 180°, so we can set up equation accordingly:
3. m<E + m<F + m<D = 180°
6x + 1 + 68 + 13x - 3 = 180
19x + 66 = 180
19x = 114
x = 6°
We can substitute the value of x back into the expressions for each angle:
m<E = 6x + 1 = 6(6) +1 = 36 + 1 = 37°
m<F = 68°
m<D = 13x - 3 = 13(6) - 3 = 75°
4. m<G + m<I + m<H = 180°
2x + 2x + 4x - 20 = 180
8x - 20 = 180
8x = 200
x = 25°
We can substitute the value of x back into the expressions for each angle:
<G = 2x = 50°
<H = 4x - 20 = 4(25) - 20 = 80°
<I = 2x = 50°
5. m<B + m<C + m<A = 180°
90 + 3x + 5 + 5x + 5 = 180
100 + 8x = 180
8x = 80
x = 10°
We can substitute the value of x back into the expressions for each angle:
<A = 5x + 5 = 5(10) + 5 = 55°
<B = 90°
<C = 3x + 5 = 3(10) + 5 = 35°
