Answer:

x = 2

Step-by-step explanation:

Since the parabola is opening vertically up then the equation of symmetry is vertical and of the form x = c

The axis of symmetry passes through the vertex (2, 0), thus

equation of axis of symmetry is x = 2

What is the measure of angle DEB in degrees? Explain howyou know. i need help

viktelen [127]

Looking at the given diagram, angle AEC and angle DEB share the same vertex, E. They are described as vertically opposit angles. In geometry, vertically opposite angles are equal. This means that

Angle DEB = angl AEC = 50 degrees

I am confused my teacher helped on the first problem but the rest didn't make sense any idea's?

Dovator [93]

2. The three points you need to mark on this graph are (1,2) (2,3) and (4,5); you then draw a line through all of these points and determine whether the inches of rainfall is proportionate to the number of hours.

You mark those 3 points because at 1 hour, 2 inches of rain has fallen; at 2 hours, 3 inches of rain has fallen; and at 4 hours, 5 inches of rain has fallen

Celesta wants to go on a cruise in three years. She could earn 8.2 percent compounded monthly in an account if she were to depos

Nezavi [6.7K]

Given:

Amount after three years = $10000

Rate of interest = 8.2 percent compounded monthly = 0.082

Time = 3 years

To find:

The principal value.

Solution:

Formula for amount is

$A=P\left(1+\dfrac{r}{n}\right)^{nt}$

where, P is principal, r is rate of interest, n is the number of times interest compounded in an year, t is number of years.

Substitute A=10000, r=0.082, n=12 and t=3 in the above formula.

$10000=P\left(1+\dfrac{0.082}{12}\right)^{12(3)}$

$10000=P\left(1+\dfrac{41}{6000}\right)^{36}$

$10000=P\left(\dfrac{6041}{6000}\right)^{36}$

$10000=P(1.27783)$

Divide both sides by 1.27783.

$\dfrac{10000}{1.27783}=P$

$7825.76712=P$

$P\approx 7825.767$

Therefore, today she have to deposit $7825.767.

You are volunteering to help with the soccer team fundraiser for Valentine's Day. Your team promised to deliver one 16 ounce bag

icang [17]

The student, who suggests that if we do half and half of each bag, we will be giving them at least 60%,<u> is correct</u>.

<h3>What is the implication of the phrase "at least"?</h3>

The phrase "at least" means the minimum that is true or possible.

Mathematically, by "at least," we mean 'equal to or greater than.'

<h3>Data and Calculations:</h3>

Since each bag of nuts contain 16 ounces,

The 1st bag contains x/2 ounces (50%) of plain nuts and x/2 ounces (50%) of chocolate-covered nuts.

The 2nd bag contains x/5 ounces (20%)of plain nuts and 4x/5 ounces (80%) of chocolate-covered nuts.

If half of the 1st bag is mixed with half of the 2nd bag, each bag will contain only 65% (that is, 25% (50%/2) from the 1st bag and 40% (80%/2) from the 2nd bag).

Thus, the student, who suggests that if we do half and half of each bag, we will be giving them at least 60%, <u>is correct</u> since they will not be given less than 60% of chocolate-covered nuts inside.

Qhat is the measure of each interior angle of a regular hexagon

Dmitrij [34]

120°

the sum of the interior angles of a polygon = 180°( n - 2)

where n is the number of sides

here n = 6 ⇒ sum = 180° × 4 = 720°

thus each interior angle = $\frac{720}{6}$ = 120°
