In an isosceles triangle, the altitude and median are __________. I know they are the same but the same isn't one of the choices. These are the choices:
A. segments opposite one another
B. perpendicular segments
C. the same segment
D. the legs of the triangle,

Answers

C. The same segment. In an isosceles triangle, the altitude and the median are the same segments because they correspond to the base that is contained in the mediatrix of the base. This applies to equilateral and isosceles triangles and the demonstration is by the congruence of triangles.

Hi could u plz help me anyone please

Answers

Hello,

To find this solution, you have to write an inequality. We want the new plan to be less than the old plan of $175.

So our inequality would be:
94 + 4.5x < 175
Solving it gives:
4.5x < 81
x < 18

So the number of devices must be less than 18. Draw an open circle at 18 with a ray going to the left to show those numbers.

Good luck,

laura budgets $54 each month for annual expenses. she nets $1820 semimonthly. what percent of her net monthly income does she budget for annual expenses?

1%

3%

6%

8%

Answers

Answer: The correct answer is 1%.

If she is getting $1820 semimonthly. That means that she is getting $3640 per month. 1820 x 2 = 3640

Now, we just need to find the percent of that which goes for the annual expenses.

Divide 54 by 3640 and multiply by it 100 to get a percent of 1.4% which can be rounded to 1%.

Answer:

Explanation:

Since the income known in the problem is for semi-monthly (meaning every half of the month), we should compute for the monthly income because we what know is the amount of money Laura allots on a monthly basis for her annual expenses.

Since semi-monthly income is received twice per month, the monthly income of Laura is two times her semi-monthly income (= $1820). That is,

monthly income
= 2 × semi-monthly income
= 2 × $1820
monthly income = $3,640

Because $54 is budgeted each month for annual expenses, the percentage of the monthly income that is allocated for annual expenses is computed as

percentage of the monthly income
= ((monthly income allocated for annual expenses) ÷ (monthly income)) × 100%
= ($54 ÷ $3,640) × 100%
≈ 0.0148351648 × 100%
percentage of the monthly income ≈ 1%

To solve for the inverse of a function, you have to interchange the variables x and y and solve for the value of y in terms of x:

F(x) = 5x/3 + 5

y = 5x/3 + 5

Interchange x and y:

x = 5y/3 + 5

Solve for the value of y in terms of x:

x – 5 = 5y/3

5y = 3 (x – 5)

y = 3 (x -5) / 5

f^-1 (x) = 3 (x -5) / 5

Answers

3.75+15+2.6+4.25=$25.60 *1.2 = $30.72

Answer:

The total cost of her dinner including tip would be $30.72

Step-by-step explanation:

Marge orders the following items on her meal.

Soup = $3.75

Shrimp scampi = $15.00

Iced tea = $2.60

Dessert = $4.25

The total cost of her dinner including gratuity is

3.75 + 15.00 + 2.60 + 4.25 = $25.60

She would like to leave a 20% tip based on her bill

Therefore, 20% of $25.60

= 0.20 × 25.60 = $5.12

Now add this tip amount to the bill amount.

$25.60 + $5.12 = $30.72

The total cost of her dinner including tip would be $30.72

The number of ants in a colony doubles every 8 weeks.

Answers

The number of ants in a colony doubles every 8 weeks.

Constant rate of change means that when the value of x increases, the y remains constant. So there is no change in the y value. In this case, the x value is the "week" and the y value is the "amount of ants".

a. Identify the coordinates of the center of the ellipse.
b. Find the length of the major and minor axes.
c. Find the coordinates of the foci.
d. Graph the ellipse. Label the center and foci.,

Answers

Your ellipse is given in the form:
[tex]\frac{(x - xc)^{2} }{ a^{2} } + \frac{(y - yc)^{2} }{ b^{2} } = 1[/tex]

Indeed, you have:

[tex]\frac{(x-3)^{2} }{64} + \frac{(y+5)^{2} }{100} = 1[/tex]

Therefore you can easily find:

a) the coordinates of the center:
in your case xc = 3 and yc = -5
hence C(3 , -5)

b) lenght of the major and minor axis:
in your case a² < b²:
a² = 64 ⇒ a = 8 (ATTENTION! This is the semi-minor axis)
b² = 100 ⇒ b = 10 (again, this is the semi-major axis)
Therefore,
minor axis 2a = 16 and major axis 2b = 20

c) coordinates of the foci:
Since you have a² < b², foci have the generic coordinates F₁₂ (xc , yc+/-c)
where c = √(b² - a²)

Let's compute c = √(100 - 64) = √36 = 6
yf₁ = -5 - 6 = -11
yf₂ = -5 + 6 = -1
Therefore:
F₁ (3, -11) and F₂(3, +1)

Find the sum of the measures of the interior angles of a convex 14-gon.

Answers

sum of all interior angles = (n-2)x180, n being the number of sides.

sum of all interior angles = (n-2)x180
sum of all interior angles = (14-2)x180
sum of all interior angles = 12 x180
sum of all interior angles = 2160°

Final answer:

The sum of the interior angles of a convex 14-gon is calculated using the formula (n - 2) × 180°, which equals 2160°.

Explanation:

The sum of the interior angles of any polygon can be found using the formula (n - 2) × 180°, where n is the number of sides. For a convex 14-gon, we plug in 14 for n in the formula to find the sum:

sum of all interior angles = (n-2)x180, n being the number of sides.

Sum = (14 - 2) × 180°

Sum = 12 × 180°

Sum = 2160°

This calculation shows that the sum of the interior angles of a convex 14-gon is 2160 degrees.

Answers

Answer: (f/g)(x) = Quantity five x plus three divided by six x minus five.domain {x|x ≠ Five over six. }

Explanation:

1) (f/g)(x) = f(x) / g(x)

2)

f(x) 5x + 3
-------- = ------------
g(x) 6x - 5

3) Since the division by 0 is not defined, the domain is restricted to 6x - 5 ≠ 0.

Therefore you must solve 6x - 5 = 0 to exclude the value of x for which the denominator becomes 0:

6 x - 5 = 0 => 6x = 5 => x = 5 / 6.

So, the domain is all x | x ≠ 5/6.

Answer:

(f/g)(x) = Quantity five x plus three divided by six x minus five.domain {x|x ≠ Five over six. }

Step-by-step explanation:

Given functions,

[tex]f(x)=5x+3[/tex]

[tex]g(x) =6x-5[/tex]

[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

[tex]=\frac{5x+3}{6x-5}[/tex] ( By substitution )

Let [tex]h(x)=\frac{5x+3}{6x-5}[/tex]

Which is the rational function,

Since, a rational function is defined for all real number except those for which denominator = 0,

[tex]6x-5=0[/tex]

[tex]6x=5[/tex]

[tex]x=\frac{5}{6}[/tex]

Thus, h(x) is defined on all real numbers except 5/6,

Hence, domain of [tex]\frac{f}{g}(x)[/tex] is {x| x ≠ [tex]\frac{5}{6}[/tex] }

Answers

Answer:

A on Edg :)

Step-by-step explanation:

Using the normal distribution, it is found that P(z < −2.1) = 0.0179.

Normal Probability Distribution

The z-score of a measure X in a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure X is from the mean, if it is positive above the mean, if it is negative below. After finding the z-score, the z-score table gives the p-value of this z-score, which is the percentile of the measure X.

From the z-table, we have that Z = -2.1 has a p-value of 0.0179, hence P(z < −2.1) = 0.0179.

Answers

Hey,
It would be A
i just learned this 4 weeks ago in math class.

The required, experimental probability of randomly selecting a marble that is not blue is 9/11. Option C is correct.

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.

The total number of marbles in the barrel is:

4 blue + 5 yellow + 6 red + 2 green + 5 purple = 22 marbles

The number of marbles that are not blue is:

5 yellow + 6 red + 2 green + 5 purple = 18 marbles

Therefore, the experimental probability of randomly selecting a marble that is not blue is:

18 marbles / 22 marbles = 9/11

Thus, the answer is option C: 9 / 11.
