The area of a triangle is given by the formula:
\(\frac{1}{2}(\text{base x altitude)}\)Altitude is the same as the height. The base, in this case, is the side that measures 15 yards, and the height (altitude) is 5 yards. Therefore, we have:
\(A=\frac{1}{2}\cdot(15yardsx5yards)=37.5yards^2\)Thus, the area of the triangle is 37.5 square yards or 37.5 yards^2.

How much monthly deposit must be made for 7 years and 3 months to accumulateP14,500 at 7% compounded monthly?
Answers
Given:
The time of the investment = 7 years and 3 months = 7 1/4 years
The interest rate = r = 7% = 0.07
compounded monthly, n = 12
We will find the monthly deposit (P) to accumulate $14,500
We will use the following formula:
\(A=\frac{P((1+\frac{r}{n})^{nt}-1)}{\frac{r}{n}}\)Substitute: A = 14500, t = 7.25, r = 0.07, n = 12
\(\begin{gathered} 14500=P*\frac{((1+\frac{0.07}{12})^{12*7.25}-1)}{\frac{0.07}{12}} \\ \\ 14500=P*112.9175 \\ \\ P=\frac{14500}{112.9175}=128.4122874 \end{gathered}\)Rounding to the nearest tenth

Suppose a country's population at any time t grows in accordance with the rule dP dt = kP + I where P denotes the population at any time t, k is a positive constant reflecting the natural growth rate of the population, and I is a constant giving the (constant) rate of immigration into the country. If the total population of the country at time t = 0 is P0, find an expression for the population at any time t.
Answers
Answer:
\(\mathbf{P =\bigg (P_o +\dfrac{ I}{k} \bigg)e^{kt}- \dfrac{I}{k}}\)
Step-by-step explanation:
Given that:
A country population at any given time (t) is:
\(\dfrac{dP}{dt}= kP+I\)
where;
P = population at any time t
k = positive constant
I = constant rate of immigration into the country.
Using the method of separation of the variable;
\(\dfrac{dP}{kP+1}= dt\)
Taking integration on both sides:
\(\int \dfrac{dP}{kP+I}= \int \ dt\)
\(\dfrac{1}{k} log (kP + I) = t+c_1 \ \ \ here: c_1 = constant \ of \ integration\)
\(log (kP + I) =k t+kc_1\)
By applying the exponential on both sides;
\(e^{log (kP + I) }=e^{k t+kc_1 }\)
\(KP+I = e^{kt} *e^{kc_1}\)
Assume \(e^{kc_1 }= C\)
Then:
\(kP + I = Ce^{kt}\)
\(kP = Ce^{kt}-I\)
\(P =\dfrac{ Ce^{kt}-I}{k} \ \ \---- Let \ that \ be \ equation \ (1)\)
When time t = 0, The Total population of the country is also \(P_o\)
\(P_o = \dfrac{Ce^{0(t)} -I}{k}\)
\(P_o = \dfrac{Ce^{0} -I}{k}\)
\(P_o = \dfrac{C-I}{k}\)
C - I = kP₀
C = kP₀ + I
Substituting the value of C back into equation(1), we have:
\(P =\dfrac{ (kP_o+1)e^{kt}-I}{k}\)
\(P =\dfrac{ (kP_o+1)e^{kt}}{k} - \dfrac{I}{k}\)
\(\mathbf{P =\bigg (P_o +\dfrac{ I}{k} \bigg)e^{kt}- \dfrac{I}{k}}\)
Find the value of q for which the equation
qx² - 6x + 18 = 0
has one repeated real root

Answers
Answer:
q = \(\frac{1}{2}\)
Step-by-step explanation:
given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
then the nature of the roots can be found using the discriminant
Δ = b² - 4ac
• if b² - 4ac > 0 then roots are real and irrational
• if b² - 4ac = 0 then the roots are real and equal
• if b² - 4ac < 0 then the roots are not real
qx² - 6x + 18 = 0 ← is in standard form
with a = q , b = - 5 , c = 18
for one repeated (equal) real root , then
b² - 4ac = 0 ( substitute values )
(- 6)² - (4 × q × 18) = 0
36 - 72q = 0 ( subtract 36 from both sides )
- 72q = - 36 ( divide both sides by - 72 )
q = \(\frac{-36}{-72}\) = \(\frac{1}{2}\)

The Polynomial x⁵ + x³ - 5 is divided by x - 2, the quotient is x⁴ + 3x³ + 6x² + 12x + 24, and the remainder is 48.
The quotient and remainder when the polynomial x⁵ + x³ - 5 is divided by x - 2, we can use polynomial long division. Here's the step-by-step process:
1. Write the dividend (x⁵ + x³ - 5) and the divisor (x - 2).
x - 2 | x⁵ + x³ + 0x² + 0x - 5
2. Divide the first term of the dividend (x⁵) by the first term of the divisor (x) to get x⁴. Write x⁴ above the line. x⁴
x - 2 | x⁵ + x³ + 0x² + 0x - 5
3. Multiply the divisor (x - 2) by the quotient term (x⁴) to get x⁵ - 2x⁴. Write this under the dividend and subtract it. x⁴
x - 2 | x⁵ + x³ + 0x² + 0x - 5
- (x⁵ - 2x⁴)
3x⁴ + 0x³ + 0x² + 0x - 5
4. Bring down the next term (-5) from the dividend.
x⁴ + 3x³
x - 2 | x⁵ + x³ + 0x² + 0x - 5
- (x⁵ - 2x⁴)
3x⁴ + 0x³ + 0x² + 0x - 5
5. Divide the first term of the new dividend (3x⁴) by the first term of the divisor (x) to get 3x³. Write 3x³ above the line.
x⁴ + 3x³
x - 2 | x⁵ + x³ + 0x² + 0x - 5
- (x⁵ - 2x⁴)
3x⁴ + 0x³ + 0x² + 0x - 5
6. Multiply the divisor (x - 2) by the new quotient term (3x³) to get 3x⁴ - 6x³. Write this under the new dividend and subtract it.
x⁴ + 3x³
x - 2 | x⁵ + x³ + 0x² + 0x - 5
- (x⁵ - 2x⁴)
3x⁴ + 0x³ + 0x² + 0x - 5
- (3x⁴ - 6x³)
6x³ + 0x² + 0x - 5
7. Repeat steps 4-6 until you have subtracted all terms.
x⁴ + 3x³ + 6x² + 12x + 24
x - 2 | x⁵ + x³ + 0x² + 0x - 5
- (x⁵ - 2x⁴)
3x⁴ + 0x³ + 0x² + 0x - 5
- (3x⁴ - 6x³)
6x³ + 0x² + 0x - 5
- (6x³ - 12x²)
12x² + 0x + 0
- (12x² - 24x)
24x + 0
- (24x - 48)
48
8. The quotient is x⁴ + 3x³ + 6x² + 12x + 24, and the remainder is 48.
Therefore, when the polynomial x⁵ + x³ - 5 is divided by x - 2, the quotient is x⁴ + 3x³ + 6x² + 12x + 24, and the remainder is 48.

x = $21
b. If the shirt is 30% off it would cost $9.80
14 x 0.3 = 4.2
14 - 4.2 = 9.8
35 is greater than or equal to 9.80 + x
35 - 9.8 = 25.2
x = $25.20
This changes the inequality by making x greater than it was in part a

MARS On Mars, the gravity acting on an object is less than that on Earth. On Earth, a golf ball hit with an initial upward velocity of 26 meters per second will hit the ground in about 5.4 seconds. The height h of an object on Mars that leaves the ground with an initial velocity of 26 meters per second is given by the equation h=−1.9t2+26t
. How much longer will it take for the golf ball hit on Mars to reach the ground? What is the maximum height of the golf ball on Mars? Round your answer to the nearest tenth.
It takes about
seconds longer for the golf ball hit on Mars to reach the ground.
The maximum height of the golf ball on Mars is about
meters.
Answers
The maximum height of the golf ball on Mars is about 48.8 meters.
To find how much longer it would take for the golf ball hit on Mars to reach the ground, we can use the given equation h = -1.9t² + 26t, where h is the height of the object and t is the time in seconds. First, we need to find the time it takes for the golf ball to reach the ground on Mars. Setting h = 0, we get:
0 = -1.9t² + 26t
Solving for t using the quadratic formula, we get t = 13.684 or t = 0.856. Since the golf ball is launched upward, we need the positive value of t, so it takes about 13.7 seconds for the golf ball to reach the ground on Mars. Therefore, it takes 13.7 − 5.4 = 8.3 seconds longer for the golf ball hit on Mars to reach the ground than the golf ball hit on Earth.
To find the maximum height of the golf ball on Mars, we can use the formula h = -1.9t² + 26t, where t is the time when the height is maximum. Since the formula is a quadratic equation, the maximum height occurs at the vertex of the parabola, which is at t = -b/2a.
In this case, a = -1.9 and b = 26, so the time at maximum height is t = -26 / 2(-1.9) = 6.842. Plugging this value into the equation for h, we get:
= -1.9(6.842)² + 26(6.842) ≈ 48.8 meters

The distance between points R and S is \(\sqrt{ (185)\). The correct answer is D. She made no errors.
Heather's work to find the distance between two points, R(-3,-4) and S(5,7), is shown:
RS = √(-4) (-3))² + (7 − 5)²
= √(-1)² + (2)²= √1 + 4
= √5
The error is with the order of subtraction in the formula for the distance between two points.
Heather did not make any errors in calculating the distance between two points. Therefore, the correct answer to the question above is (OD) She made no errors.
The formula for the distance between two points, A (x1, y1) and B (x2, y2), in the coordinate plane is given as;
dAB = \(\sqrt{ ((x^2 - x1)^2 + (y2 - y1)^2)\)
Comparing the given question with the formula above, we have;
A = R (-3, -4) and B = S (5, 7)The distance, AB = RS.
Therefore, we have;
RS = \(\sqrt{ ((5 - (-3))^2 + (7 - (-4))^2)\)
On solving the above equation;RS = \(\sqrt{ ((5 + 3)^2 + (7 + 4)^2)\)RS
= \(\sqrt{ (8^2 + 11^2)RS\)
= \(\sqrt{ (64 + 121)RS\)
= \(\sqrt{ (185)\)
Therefore, the distance between points R and S is \(\sqrt{ (185)\).
From the calculation, it is clear that Heather did not make any errors while calculating the distance between two points. The answer obtained by Heather is correct.
