m/CDF = 43°, find each measure.
x =
m/GDH=
mZFDH=
m/FDE =
Answer:
From the way the problem is worded:
CDE is a straight angle made up of three angles: CDF of measure 43, FDG of unknown measure and GDE of measure 8x + 1.
EDH is outside CDE and is of measure 6x + 15.
Since DE bisects GDH to form GDE and EDH, those latter two angles are equal and thus 8x + 1 = 6x + 15 and x = 7 and substituting 7 for x, both angles are equal to 57 degrees.
Since CDF is 43 and GDE is 57 and CDE is 180 in total, then FDG = 180 - 43 - 57 = 80 degrees.

question one-half cup of black beans provides 15% of the potassium you need daily. you must get the remaining 2890 milligrams from other sources. how many milligrams of potassium should you consume daily? question one-half cup of black beans provides 15% of the potassium you need daily. you must get the remaining 2890 milligrams from other sources. how many milligrams of potassium should you consume daily?
The amount of potassium you should consume daily is 510 miligrams if 15 percent of potassium you daily need.
Let the total amount of sources of nutrient you consumed daily be x miligrams.
According to the given question.
One-half cup of black beans provides 15 percent of the potassium.
Also, you get remaning nutrients from 2890 miligrams of other sources.
⇒ you get 85 percent of remaining nutrients from other sources.
So, we can say that
85 percent of x = 2890 miligrams
⇒ 85/100 × x = 2890 miligrams
⇒ x = (2890 × 100)/85
⇒ x = 3400
So, the total amount of source of nutrients is 3400.
Therefore,
The amount of potassium you should consume daily
= 15 percent of 3400
= (15/100) × 3400
= 15 × 34
= 510 miligrams
The amount of potassium you should consume daily is 510 miligrams if 15 percent of potassium you daily need.

Which table represents a linear function?
Answer:
Option C.
Step-by-step explanation:
For a table to be linear, the table must have a constant and even rate of change, meaning as X, the input, increases by 1, Y, the output, increases evenly by a random number we're gonna name "a". Now, a, in this case, is -8. The numbers increase evenly by -8(a), which would classify that function as linear. Thus, option C. is the correct answer.

What is per capita consumption?Per capita consumption is the yearly use of services and goods by each individual, calculated by dividing the total population's use of goods and services. This variable measures personal economic well-being directly.So,
According to the data, per capita consumption was 39.7 pounds in 1983 and 47 pounds in 1989.Per capita consumption is the yearly use of services and goods by each individual, calculated by dividing the total population's use of goods and services. This variable measures personal economic well-being directly.Assume t=0 corresponds to the year 1980.As a result, we can express the given data as ordered pairs (3,39.7) and (9,47).We can compute a linear function that passes through these points.Let us first calculate the slope of the linear function:
[tex]m=\frac{y_2-y_1}{t_2-t_1}=\frac{47-39.7}{9-3}=\frac{7.3}{6}=\frac{73}{60}[/tex]The required linear function can be written as:
[tex]y-39.7=\frac{73}{60}(t-3)[/tex]When we simplify this, we get:
[tex]y=\frac{73}{60} t+\frac{721}{20}[/tex]To calculate per capita consumption in 1995, enter t=15 into this function.

As the sample size increases, the margin of error a. decreases
What is a margin of error?In a random survey sample, the margin of error is a statistical measure that takes into account the discrepancy between actual and anticipated findings. Simply said, you may determine the degree of unpredictability in data and research results using the margin of error.
The number of distinct samples that are measured or observations that are used in a survey or experiment is known as the sample size. For instance, your sample size is 100 if you examine 100 samples of soil for signs of acid rain. If 30,500 completed questionnaires from an online survey were returned, your sample size is 30,500.

If alpha and beta are the roots of 3x²-4x+1. Find
a) alpha²-beta²
b) 2/alpha²+2/beta²
c)2/alpha²-2/beta²
From Vieta's formulas, we have
[tex]3x^2 - 4x + 1 = 3 (x - \alpha) (x - \beta) \\\\ ~~~~~~~~~~~~~~~~~ = 3x^2 - 3 (\alpha + \beta) + 3\alpha\beta \\\\ \implies \begin{cases} \boxed{\alpha + \beta = \frac43} \\\\ \boxed{\alpha\beta = \frac13} \end{cases}[/tex]
a) Note that
[tex](\alpha + \beta)^2 = \alpha^2 + 2\alpha\beta + \beta^2 \\\\ \implies \alpha^2 - \beta^2 = (\alpha+\beta)^2 - 2\alpha\beta - 2\beta^2[/tex]
We have exact values for [tex]\alpha+\beta[/tex] and [tex]2\alpha\beta[/tex], but sadly not for [tex]-2\beta^2[/tex]. This means we'll need to solve for [tex]\beta[/tex] explicitly.
By factorizing, we have
[tex]3x^2 - 4x + 1 = (3x - 1) (x - 1) = 0 \\\\ \implies x = \dfrac13 \text{ or } x = 1[/tex]
Then the value of [tex]\alpha^2-\beta^2[/tex] depends on which is chosen to be the larger root, and
[tex]\alpha^2 - \beta^2 = \dfrac1{3^2} - 1^2 = \boxed{-\dfrac89} \text{ or } \alpha^2 - \beta^2 = 1^2 - \dfrac1{3^2} = \boxed{\dfrac89}[/tex]
While we're at it, we can also immediately find
[tex]\alpha^2 + \beta^2 = (\alpha + \beta)^2 - 2\alpha\beta = \left(\dfrac43\right)^2 - 2\cdot\dfrac13 = \dfrac{10}9[/tex]
b) Combine fractions to get
[tex]\dfrac2{\alpha^2} + \dfrac2{\beta^2} = \dfrac{2\beta^2 + 2\alpha^2}{\alpha^2\beta^2} \\\\ ~~~~~~~~~~~~~ = 2 \cdot \dfrac{\alpha^2 + \beta^2}{(\alpha\beta)^2} \\\\ ~~~~~~~~~~~~~ = 2\cdot \dfrac{\frac{10}9}{\left(\frac13\right)^2} \\\\ ~~~~~~~~~~~~~ = \boxed{20}[/tex]
c) Combine fractions again.
[tex]\dfrac2{\alpha^2} - \dfrac2{\beta^2} = 2 \cdot \dfrac{\beta^2 - \alpha^2}{(\alpha\beta)^2} \\\\ ~~~~~~~~~~~~~ = -2\cdot \dfrac{\pm\frac89}{\left(\frac13\right)^2} \\\\ ~~~~~~~~~~~~~ = \boxed{\pm16}[/tex]

What is referred as the solid right pyramid?A right pyramid is one that has the upper end straight just above centroid of a base. A regular pyramid is thus a subset of a right pyramid.
As, per the given question;
Edge Length = n units
Height of the pyramid = n - 1 units

Volume = ⅓Ah
Where, A is the area of the base.
h is the height of the pyramid
Since, pyramid has the square base;
Calculate the area;
Area, A = edge × edge
A = n × n
A = n²
Put the value of area in volume;
Volume = ⅓Ah
Substitute n² at A and n - 1 at h.
Solve the expression;
Volume = ⅓ × n² × (n - 1)
