C.) x = 36/25, x = -36/25
D.) x = 6/5, x = -6/5
Answers
Answer: 6/5 and -6/5
Step-by-step explanation: In order to solve this problem, we want to get the variable on one side. In order to do that, we must do the following:
Add 36 on Both Sides:
[tex]25x^2 - 36+36 = 0+36[/tex]
Divide 25 on Both Sides:
[tex]\frac{25x^2}{25}= \frac{36}{25}[/tex]

y=({x}^2)-8x+15 and y=3x+15 (Once again plz solve using a method other than graphing and add an explanation)
Answers
Answer:
(0, 15) and (11, 48)
Step-by-step explanation:
Given the 2 equations
y = x² - 8x + 15 → (1)
y = 3x + 15 → (2)
Substitute y = x² - 8x + 15 into (2)
x² - 8x + 15 = 3x + 15 ( subtract 3x + 15 from both sides )
x² - 11x = 0 ← in standard form
x(x - 11) = 0 ← in factored form
Equate each factor to zero and solve for x
x = 0
x - 11 = 0 ⇒ x = 11
Substitute these values into (2) for corresponding values of y
x = 0 : y = 0 + 15 = 15 ⇒ (0, 15)
x = 11 : y = 33 + 15 = 48 ⇒ (11, 48)
Solutions are (0, 15), (11, 48)

Water has a density of about 0.0361 pounds/cubic inch. You might know that wood floats on water. What can you conclude about the densities of objects that float and the densities of objects that do not?
Answers
Answer:
Step-by-step explanation:
Objects that float on water have densities less than the density of water; those that do not float on water have densisties greater than the density of water:
Float on water: d < 0.0361 lb/in³ (where d denotes denisity)
Do not float on water: d > 0.0361 lb/in³
The densities of objects that float on water are lower than those of objects that don't float.
What is density?It is defined as the mass-to-volume ratio. The density indicates the object's density and is represented by the symbol. The density is measured in kilograms per cubic meter.
We have:
Water has a density of about 0.0361 pounds/cubic inch.
Let d be the density:
Float on water: d < 0.0361 lb/in³
Do not float on water: d > 0.0361 lb/in³
The densities of objects that float on water are lower than those of objects that don't, which have densities higher than those of water.
Thus, the densities of objects that float on water are lower than those of objects that don't float.

The equation for a parabola with directrix y = –p and focus (0, p) is:
Answers
Answer:
[tex]y=\frac{1}{4p}x^{2}[/tex]
Step-by-step explanation:
∵ The directrix is y = -p
∵ The focus is (0 , p)
∵ (x , y) is a general point on the parabola
∵ The distance between (x , y) and the directrix = the distance
between (x , y) and the focus
By using the rule of distance:
∵ (y - -p)² = (x - 0)² + (y - p)²
∴ (y + p)² = x² + (y - p)²
∴ y² + 2py + p² = x² + y² - 2py + p²
∴ 2py + 2py = x²
∴ 4py = x² ⇒ ÷ 4p in both sides
∴ [tex]y=\frac{1}{4p}x^{2}[/tex]

Answers
the measure is 140, I basically summed all of the angles of a polygon of “n”, which is 7, then I did 7-2 times 180 (900) so I can finally add up all of your measurements
The seventh angle of the given Heptagon is 140 degrees.
What is Heptagon?A heptagon is a polygon that has seven sides. It is a closed figure having 7 vertices. A heptagon is also sometimes called Septagon.
Given, six angles of a heptagon measure 107, 139, 131, 110, 145. and 128.
Since, Sum of all angles of Heptagon is 900°
Let "x" be the seventh angle of Heptagon
thus,
107 + 139 + 131 + 110 + 145 + 128 + x = 900
760 + x = 900
x = 140
Therefore, The seventh angle of the given Heptagon is 140 degrees.

In a sample of 32 city residence, 24 reported that they take vitamin C supplement daily. There are 46,480 residence in the city. Which estimate represents the number of city residents who take vitamin C supplement daily?
Answers
Answer:
34,860
Step-by-step explanation:
In a sample of 32 residence, 24 take Vitamin C. From here we can get the proportion of residents who take Vitamin C, which is 24/32 = 3/4 = 0.75
0.75 in percentage is 75%. This means 75% of the residents in sample take Vitamin C.
We can expect the same percentage of people in entire population to take Vitamin C.
Total population of city = 46480
Expected number of residents who take vitamin C in the city = 75% of 46480
= 0.75 x 46480
= 34860
This means, 34860 is an estimate of number of city residents who take Vitamin C supplement daily.
Based on the sample study and assuming its representativeness of the general population, it is estimated that approximately 34,860 residents of the city take a vitamin C supplement daily.
Explanation:In the sample study, the proportion of residents who take vitamin C supplements daily is calculated by dividing the number of individuals who reported taking the supplement (24) by the total number of individuals in the sample (32). This yields a proportion of 0.75, or 75%. Then, we can apply this proportion to the total population of the city to estimate the number of residents who take vitamin C daily. Therefore, the estimated number is 0.75 * 46,480 = 34,860.
In conclusion, assuming that the small sample is representative of the larger population, we would estimate that "approximately 34,860" city residents take a vitamin C supplement daily.

Two points are 10 units apart on the coordinate plane. If
an ant were to walk between the 2 points moving only
vertically and horizontally, it would have to walk 6 horizontal
units. How many vertical units would the ant have to walk?
Answers
Answer:
The vertical distance the ant have to walk is 8 units
Step-by-step explanation:
∵ The ant must be walk vertically and horizontally
∴ The distance from start point to end point will be as
a hypotenuse of a right angle triangle
∵ The ant would have to walk 6 units horizontally that
means one side of the right angle is 6 units
∵ The two points are apart by 10 units that means
the length of the hypotenuse is 10 units
∴ The vertical distance the ant would have to walk is
the length of the second side of the right angle
* By using Pythagoras Theorem:
∵ (hypotenuse)² = (horizontal leg)² + (vertical leg)²
∴ 10² = 6² + (vertical leg)²
∵ (vertical leg)² = 100 - 36 = 64
∴ Vertical leg = √64 = 8 units
∴ The vertical distance the ant have to walk is 8 units

If ec bisects are congruent to bed find m bed ..??
Answers
Answer:
m<BED = 136 deg
Step-by-step explanation:
Since ray EC bisects <BED, angles BEC and CED are congruent. That means their measures are equal. Set the measures equal to each other, and solve for x.
11x + 2 = 8x + 20
Subtract 8x from both sides.
3x + 2 = 20
Subtract 2 from both sides.
3x = 18
Divide both sides by 3.
x = 6
Now we use the value of x to find the measure of angle BED.
The measure of angle BED is twice the measure of angle BEC. We know that x = 6.
m<BED = 2m<BEC = 2(11x + 2) = 2(11 * 6 + 2) = 2(66 + 2) = 2(68) = 136

Whether public goods should be paid for through taxes or individual fees depends on various factors, including the nature of the good and one's income level. For many public goods and services, a combination of tax funding and user fees is used. The decision between the two is a matter of public policy and individual preference.
Explanation:The decision on whether to pay for public goods through taxes or individual fees depends on various factors. In essence, this relates to the discussion on public provision versus personal pay-per-use. Some public goods, like parks, are free to use, but the government charges for certain services, such as parking or reserving picnic areas. This is a mixture of public provision at no charge along with fees for some purposes.
On the other hand, taxes are paid by most working people and by consumers when they buy goods and services. These taxes fund public services like roads, bridges, schools, and public safety functions. Thus, some may prefer public goods to be funded through taxes so everyone contributes to these community-supporting services.
Nonetheless, there are also 'toll goods', like cable TV and private schools, that are open to everyone but require users to pay a fee. The choice between taxes versus individual fees can also depend on one's income level, as those with more discretionary income might prefer pay-per-use to avoid potential higher taxes.
