Answer: x = 20
Step-by-step explanation: We can use the Segment Addition Postulate.
If N is between M and P, then MN + NP = MP.
So we have 2x + 7 + 13 = 3x.
Solving from here, first simplify the left side to get 2x + 20 = 3x.
Now subtract 2x from both sides ti get 20 = x.
So the value of x is 20.

Two projectiles are shot vertically upward at the same instant.
Projectile A's height in feet, f(t), is represented in the table, where t is the seconds since the projectile was shot off
Projectile B's height at any time t is modeled by the function
h (t)=-16t^2 +96t
How do the times at which the projectiles begin their descents compare?

What is y-intercept?In Mathematics and Geometry, the y-intercept of any graph or table such as a quadratic equation or function, generally occurs at the point where the value of "x" is equal to zero (x = 0).
By critically observing the table shown in the image attached above, we can reasonably infer and logically deduce the following y-intercept of Projectile A:
y-intercept = (0, 44).
Maximum height = (4, 300).
When t = 0, the y-intercept of Projectile B can be calculated as follows;
h(t) = -16t² + 96t
h(0) = -16(0)² + 96(0)
h(0) = 0.
For the maximum height, we have:
h(t) = -16t² + 96t
h'(t) = -32t + 96
32t = 96
t = 96/32
t = 3
Difference in time = 4 - 3
Difference in time = 1 seconds.

What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
Suppose that the given quadratic equation is
ax² + bx + c = 0
Then its roots are given as:
[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
For the given equation, the value of a, b, and c is 1, -10, and 125, respectively. The roots of the given quadratic equation are,
[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \dfrac{-(-10) \pm \sqrt{(-10)^2 - 4(1)(125)}}{2(1)}\\\\x = \dfrac{10 \pm \sqrt{100 - 500}}{2}\\\\x = \dfrac{10 \pm 20i}{2}\\\\[/tex]

Answers
Answer:
Step-by-step explanation:
1). m∠AEC = m∠AEB + m∠BEC
= 21° + 37°
= 58°
2). m∠BED = m∠BEC + m∠CED
= 37° + 44°
= 81°
3). m∠IKF = m∠IKH + m∠HKG + m∠GKF
= m∠IKH + m∠HKG + m∠IKH [Since, ∠IKH ≅ ∠GKF]
= 2∠IKH + m∠HKG
103° = 2∠IKH + 41°
2(∠IKH) = 103 - 41
m(∠IKH) = 31°
4). m∠AED = m∠AEB + m∠BEC + m∠CED
= 21° + 37° + 44°
= 102°
5). m∠JKG = 108°
m∠JKG = m∠JKI + m∠IKH + m∠HKG
108° = m∠JKI + 31° + 41°
m∠JKI = 108° - 72°
m∠JKI = 36°
6). m∠HKF = m∠GKF + m∠HKG
= m∠IKH + m∠HKG [Since, m∠GKF = m∠IKH]
= 31° + 41°
= 72°
7). m∠NQO = m∠MQN = 64°
8). m∠JKF = m∠JKI + m∠IKF
= 36° + 103°
= 139°
8). m∠MQO = 2(m∠NQO)
= 2(64)°
= 128°
9). m∠LQO = 156°
m∠LQM = m∠LQO - m∠MQO
= 156° - 128°
= 28°
10. m∠NQP = m∠NQO + m∠OQP
= 64° + m∠LQM [Since ∠OQP ≅ ∠LQM]
= 64° + 28°
= 92°

Explanation:
The toco toucan, Ramphastos toco, is the largest member of the toucan family and possesses the largest beak relative to body size of all birds. This exaggerated feature has been interpreted in various ways, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases.
The table provided contains data for beak heat loss, as a percent of total body heat loss, at various temperatures in degrees Celsius:
Temperature (∘C) 1515 1616 1717 1818 1919 2020 2121 2222
Percent heat loss from beak 3232 3434 3535 3333 3737 4646 5555 5151
Temperature (∘C) 2323 2424 2525 2626 2727 2828 2929 3030
Percent heat loss from beak 4343 5252 4545 5353 5858 6060 6262 6262
Required:
a. What is the equation of the least‑squares regression line for predicting beak heat loss, as a percent of total body heat loss, from temperature?
b. What percent of the variation in beak heat loss is explained by the straight‑line relationship with temperature?
Answers
Answer:
(a) [tex]\hat y=0.919+2.065x[/tex]
(b) 83.6%
Step-by-step explanation:
(a)
A least square regression line is to be formed for predicting beak heat loss, as a percent of total body heat loss, from temperature.
Use MS-Excel to form the regression line.
Go to Data → Data Analysis → Regression
A dialog box will open.
Select the X and Y variables.
Press OK.
The regression output is attached below.
The equation of the least‑squares regression line is:
[tex]\hat y=0.919+2.065x[/tex]
(b)
The coefficient of determination R² specifies the percentage of the variance in the dependent variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent variable).
Consider the regression output attached below.
The R² value is 0.8360.
That is 83.6% of the variation in beak heat loss is explained by the straight‑line relationship with temperature.

Please help! I struggle with math so much! Can someone please explain! (2x−6)+4(x−3) =
Answers
Answer:
x = 3
Step-by-step explanation:
Simplifying
(2x + -6) + 4(x + -3) = 0
Reorder the terms:
(-6 + 2x) + 4(x + -3) = 0
Remove parenthesis around (-6 + 2x)
-6 + 2x + 4(x + -3) = 0
Reorder the terms:
-6 + 2x + 4(-3 + x) = 0
-6 + 2x + (-3 * 4 + x * 4) = 0
-6 + 2x + (-12 + 4x) = 0
Reorder the terms:
-6 + -12 + 2x + 4x = 0
Combine like terms: -6 + -12 = -18
-18 + 2x + 4x = 0
Combine like terms: 2x + 4x = 6x
-18 + 6x = 0
Solving
-18 + 6x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 6x = 0 + 18
Combine like terms: -18 + 18 = 0
0 + 6x = 0 + 18
6x = 0 + 18
Combine like terms: 0 + 18 = 18
6x = 18
Divide each side by '6'.
x = 3
Simplifying
x = 3
Answer:
the answer is 6x-18

A hospital sends an invoice to a patient. The patient schedules a payment plan in which she makes an initial payment of $1,451 the first month and then pays one-third of the previous month’s payment each of the following months until the invoice is paid in full. Approximately how much of the invoice will be paid after the fourth month?
$1,451.00
$2,095.89
$2,149.63
$2,167.54
Answers
Answer:
$2,149.63
Step-by-step explanation:
She makes an initial payment of $1,451 and pays one-third of the previous month's payment each of the following months.
1/3 × $1,451 = $483.67 (second month)
$483.67 + $1,451 = $1,934.67
1/3 × $483.67 = $161.22 (third month)
$161.22 + $1,934.67 = $2,095.89
1/3 × $161.22 = $53.74 (fourth month)
$53.74 + $2,095.89 = $2,149.63
$2,149.63 of the invoice will be paid after the fourth month.
Hope that helps.
Approximately $2,149.63 of the invoice will be paid after the fourth month.

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The patient makes an initial payment of $1,451 in the first month.
In each subsequent month, the patient pays one-third of the previous month's payment.
Let P be the amount paid in the first month, and let M be the amount paid in each subsequent month.
Then we have:
P = $1,451
M = (1/3)P
So the amounts paid in each month are:
Month 1: $1,451
Month 2: (1/3)P = (1/3)($1,451) = $483.67
Month 3: (1/3)M = (1/3)($483.67) = $161.22
Month 4: (1/3)M = (1/3)($161.22) = $53.74
The total amount paid after four months.
= $1,451 + $483.67 + $161.22 + $53.74
= $2,149.63
Therefore,
Approximately $2,149.63 of the invoice will be paid after the fourth month.
