What percentage do you have invested in bonds if your portfolio consists of $45,000 invested in U.S. Treasuries, $32,000 in high-grade corporate
bonds, and $74,000 in growth stocks?
51%
45%
50%
52%
To find the percentage invested in bonds, we need to add the amounts invested in U.S. Treasuries and high-grade corporate bonds, and then divide by the total value of the portfolio:
Total amount invested in bonds = $45,000 + $32,000 = $77,000
Total portfolio value = $45,000 + $32,000 + $74,000 = $151,000
Percentage invested in bonds = (Total amount invested in bonds / Total portfolio value) x 100%
= ($77,000 / $151,000) x 100%
= 51.0%
Therefore, the answer is 51%.

Factor completely 3x^2 - 147
Answer:
3(x-7)(x+7)
Step-by-step explanation:
In order to completely factor, begin by factoring out the greatest common factor. Both terms are divisible by 3 so 3 is the greatest common factor. 3(x^2-49). In order to completely factor, recognize x^2-49 as the difference of squares. Factor that into 3(x+7)(x-7).
Answer:
3(x+7)(x-7)
Step-by-step explanation:
Hello!
We can start by taking out the coefficient of 3 by factoring it out.
Factor:
The process of removing a factor or coefficient by dividing it out from the expression.
Factor the expression:
Remove the coefficient of 3
3x² - 1473(x² - 49)Factor using the product rule: a² - b² = (a+b)(a-b)

Determine coordinates of D on trapezium when A(-2;-2) and Cc(-3/4;-6) and midpoint of AD(-1/2;3)
The coordinates of D on the trapezium is (1, 8)
How to determine the coordinates of D on the trapezium?The coordinates are given as
A = (-2,-2)
C = (-3/4, -6)
Midpoint AD = (-1/2,3)
The midpoint is calculated as
Midpoint = 1/2 * (x1 + x2, y1 + y2)
So, we have the following:
Midpoint AD = 1/2 * (x1 + x, y1 + y)
This gives
(-1/2, 3) = 1/2 * (-2 + x, -2 + y)
Multiply through the equation by 2
So, we have
(-1, 6) = (-2 + x, -2 + y)
Evaluate the values of x and y in the equations
So, we have
-2 + x = -1
-2 + y = 6
This gives
x = 1
y = 8
So, we have
D = (1, 8)
Hence, the coordinates of D on the trapezium is (1, 8)

Right triangle EFG has its right angle at F, EG = 6 , and FG = 4 What is the value of the trigonometric ratio of an angle of the triangle? Drag a value to each box to match the trigonometric ratio with its value .
Answer:
\(\cos G=\dfrac{2}{3}\)
\(\csc E=\dfrac{3}{2}\)
\(\cot G=\dfrac{2}{\sqrt{5}}\)
Step-by-step explanation:
If the right angle of right triangle EFG is ∠F, then EG is the hypotenuse, and EF and FG are the legs of the triangle. (Refer to attached diagram).
Given ΔEFG is a right triangle, and EG = 6 and FG = 4, we can use Pythagoras Theorem to calculate the length of EF.
\(\begin{aligned}EF^2+FG^2&=EG^2\\EF^2+4^2&=6^2\\EF^2+16&=36\\EF^2&=20\\\sqrt{EF^2}&=\sqrt{20}\\EF&=2\sqrt{5}\end{aligned}\)
Therefore:
EF = 2√5FG = 4EG = 6\(\hrulefill\)
To find cos G, use the cosine trigonometric ratio:
\(\boxed{\begin{minipage}{9 cm}\underline{Cosine trigonometric ratio} \\\\$\sf \cos(\theta)=\dfrac{A}{H}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}\)
For angle G, the adjacent side is FG and the hypotenuse is EG.
Therefore:
\(\cos G=\dfrac{FG}{EG}=\dfrac{4}{6}=\dfrac{2}{3}\)
\(\hrulefill\)
To find csc E, use the cosecant trigonometric ratio:
\(\boxed{\begin{minipage}{9 cm}\underline{Cosecant trigonometric ratio} \\\\$\sf \csc(\theta)=\dfrac{H}{O}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}\)
For angle E, the hypotenuse is EG and the opposite side is FG.
Therefore:
\(\csc E=\dfrac{EG}{FG}=\dfrac{6}{4}=\dfrac{3}{2}\)
\(\hrulefill\)
To find cot G, use the cotangent trigonometric ratio:
\(\boxed{\begin{minipage}{9 cm}\underline{Cotangent trigonometric ratio} \\\\$\sf \cot(\theta)=\dfrac{A}{O}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}\)
For angle G, the adjacent side is FG and the opposite side is EF.
Therefore:
\(\cot G=\dfrac{FG}{EF}=\dfrac{4}{2\sqrt{5}}=\dfrac{2}{\sqrt{5}}\)

(h) f(x+h) = 4x² + 8xh + 4h² + 4x + 4h - 3.
Evaluating functions:The concept used in this question is evaluating a polynomial function for different values of the input variable. To do this, we substitute the given value into the function in place of the input variable and simplify the resulting expression.
Here we have
The function f(x) = 4x² + 4x-3.
To find the values of functions can be done by replacing x
(a) f(0) = 4(0)² + 4(0) - 3 = 0 + 0 - 3 = -3
(b) f(4) = 4(4)² + 4(4) - 3 = 64 + 16 - 3 = 77
(c) f(-4) = 4(-4)² + 4(-4) - 3 = 64 - 16 - 3 = 45
(d) -f(x) = -[4x² + 4x - 3] = -4x² - 4x + 3.
(e) f(x+1) = 4(x+1)² + 4(x+1) - 3 = 4(x² + 2x + 1) + 4x + 4 - 3 = 4x² + 12x + 1.
(f) f(-x) = 4(-x)² + 4(-x) - 3 = 4x² - 4x - 3.
(g) f(3x) = 4(3x)² + 4(3x) - 3 = 36x² + 12x - 3.
(h) f(x+h) = 4(x+h)² + 4(x+h) - 3 = 4(x² + 2xh + h²) + 4x + 4h - 3
= 4x² + 8xh + 4h² + 4x + 4h - 3.
Hence,
The values of functions are

What is linear inequality?
Linear inequalities are mathematical statements that are made up of two expressions which are compared using inequality symbols.
The following steps are to be followed to make a graph of linear inequality:-
1. Solve the inequality for y.
2. Considering the inequality as a linear equation graph the line. ( If the inequality sign does not contain an equal sign then draw a dashed line; if the inequality contains an equal sign then draw a solid line.
3. Shade the region that satisfies the inequality.

Answer:
real: 1non-real: 2Step-by-step explanation:
You want to know the number of real zeros indicated by the graph of a 3rd-degree polynomial that crosses the x-axis in one place.
Real zerosA real zero is the value of x where the value of y is zero. It is an x-intercept, a value of x where the graph crosses (or touches) the x-axis.
This function has 1 real zero.
Non-real zerosAny zeros that are not real are non-real (complex). The polynomial has a number of zeros equal to its degree. Only one of them is real, so the other two zeros of this 3rd-degree polynomial are non-real, or complex.
The function has 2 non-real zeros.

50 Points!!!!!! Triangle ABC is given.
Angle A is labeled two x degrees. Angle B is labeled forty degrees. Angle C is labeled three x degrees.
What is the measure, in degrees, of ∠A?
Enter your answer in the box.
All 3 angles add up to 180 degrees.
so 40 + 2x + 3x = 180
40 + 5x = 180
5x = 140
x = 28
So angle A = 2x = 2(28) = 56 degrees.
Answer: 56°
Step-by-step explanation:
We know that a triangle's angles add up to 180 degrees. We will create an equation to help us solve for x using this information.
Given:
2x + 3x + 40 = 180
Combine like terms:
5x + 40 = 180
Subtract 40 from both sides of the equation:
5x = 140
Divide both sides of the equation by 5:
x = 28
Next, we will substitute this value of x into the expression for ∠A.
∠A = 2x = 2(28) = 56°
