The points (0, 1), (7, 1), and (2, -3) represent the vertices of a triangle. What is the area, in square units, of the triangle?
Answer:
14 \(u^2\)
Step-by-step explanation:
The attached image shows the diagram of the triangle drawn on the Cartesian plane.
We can see that it has the following measures:
base: \(b=7u\)
height: \(h=4u\)
the area of a triangle is given by the formula:
\(A=\frac{b*h}{2}\)
substituting the values:
\(A=\frac{(7u)(4u)}{2}\\ \\A=\frac{28u^2}{2} \\\\A=14u^2\)
the area, in square units, of the triangle is 14
Let f(x)=sqrt(x). If the rate of change of f at x=c is twice the rate of change at x=1, then c=
If the rate of change of f at x=c is twice the rate of change at x=1, then c=4.
What is derivatives?
In calculus, the derivative is a mathematical concept that measures how a function changes as its input changes.
We can start by finding the derivative of f(x) using the power rule:
f'(x) = \((1/2)x^{(1/2)}\)
Then, we can find the rate of change of f at x=c by evaluating f'(c). Similarly, we can find the rate of change of f at x=1 by evaluating f'(1). We know from the problem that the rate of change at x=c is twice the rate of change at x=1, so we can write:
f'(c) = 2*f'(1)
Substituting the expressions for f'(c) and f'(1), we get:
\((1/2)c^{(-1/2)}\) = 2*(1/2)*\((1)^{(-1/2)}\)
Simplifying the right-hand side, we get:
\((1/2)c^{(-1/2)}\) = 1
Multiplying both sides by 2 and taking the reciprocal, we get:
\(c^{(1/2)}\) = 2
Squaring both sides, we get:
c = 4
Therefore, c = 4.

FACTOR 6x²- 18x - 60
Answer: 6(x+2)(x-5)
Step-by-step explanation:
1: Factor by grouping- A 6 can be distributed in all 3 terms, when we do this we get 6(x²-3x-10).
2: This is in the form 6(x²+bx+c). So, to continue factoring, just forget about the six for a while and find two factors of c that add up to b. These two factors are -5 and 2.
3: Fill in the blanks with either factor. (x+?)(x+?) We get (x+2)(x-5).
4: Bring back the 6 to the beginning of the equation to get a final answer of 6(x+2)(x-5).

What is the nature of roots of quadratic equation 9x2 12x +4?.
The nature of the roots of the quadratic equation 9x2 12x + 4 is that it has one root, which is equal to -4.
The nature of the roots of a quadratic equation is determined by its discriminant (b2 – 4ac). The discriminant of the given equation 9x2 12x + 4 is (12)2 – 4(9)(4) = 144 – 144 = 0.
Since the discriminant is equal to zero, the equation has two equal (or identical) roots. This indicates that the equation has one root since its roots are equal. We may apply the quadratic formula to get the equation's root.
The quadratic formula states that the roots of a quadratic equation can be found by solving the equation:
x = (-b ± √(b2 – 4ac))/2a
When we apply the formula to the given equation, we get:
x= (-12 ± √(0))/2(9)

Answer:
I love algebra anyways

(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
Answer:
x = - 3, y = - 11
Step-by-step explanation:
Given the 2 equations
y = 7x + 10 → (1)
y = - 4x - 23 → (2)
Substitute y = 7x + 10 into (2)
7x + 10 = - 4x - 23 ( add 4x to both sides )
11x + 10 = - 23 ( subtract 10 from both sides )
11x = - 33 ( divide both sides by 11 )
x = - 3
Substitute x = - 3 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 7(- 3) + 10 = - 21 + 10 = - 11

Scott sells scones and has collected sales data for the past few days. Scott wiill use a simple naive to forecast but is concerned about forcast accuracy. Determine what MAD (Mean Absolute Deviation) will be to 2 decimal places.
To determine the Mean Absolute Deviation (MAD), we need the actual sales data and the forecasted values. Since the actual sales data is not provided, it is not possible to calculate the MAD accurately.
MAD is calculated by taking the average of the absolute differences between the forecasted values and the actual values. Without the actual sales data, we cannot compute the absolute differences and find the MAD.
To calculate the MAD, you will need the actual sales data and the corresponding forecasted values for each day. Then, you can calculate the absolute differences between the actual and forecasted values, take their average, and round the result to two decimal places to obtain the MAD.

Use the unit circle, along with the definitions of the circular functions, to find the sec exact value for the function at the right, given s = 13π/6 sec 13π/6= __________
the exact value of sec(13π/6) is -2√3 / 3.
What is Unit circle?
The unit circle is a circle with a radius of 1 unit, centered at the origin (0, 0) in a Cartesian coordinate system. It is often used in mathematics and trigonometry to understand the relationships between angles, coordinates, and trigonometric functions.
To find the secant (sec) value for the angle 13π/6, we can use the unit circle and the definition of the secant function.
The secant function is defined as the reciprocal of the cosine function. Therefore, to find sec(13π/6), we need to find the value of the cosine function at 13π/6 and take its reciprocal.
On the unit circle, the angle 13π/6 falls in the third quadrant. Let's visualize it:
To find the cosine value at 13π/6, we can find the x-coordinate of the corresponding point on the unit circle. In the third quadrant, the x-coordinate is negative.
The reference angle for 13π/6 is π/6. The cosine value at π/6 is √3/2. However, in the third quadrant, the cosine value is negative. Therefore, the cosine value at 13π/6 is -√3/2.
Now, we take the reciprocal of -√3/2 to find the secant value:
sec(13π/6) = 1 / cos(13π/6) = 1 / (-√3/2) = -2/√3
To rationalize the denominator, we multiply the numerator and denominator by √3:
sec(13π/6) = (-2/√3) * (√3/√3) = -2√3 / 3
Therefore, the exact value of sec(13π/6) is -2√3 / 3.

What is ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b or \(\dfrac{a}{b}\)
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).
Suppose that we've got a = 6, and b= 4, then:
\(a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3\)
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Same thing happens for 3 quantities and more such quantities.
So if its given that Oli, Sam, and Tim's share (total £360) are in the ratio 3:2:1, that means some common factor (lets call it 'x') must be cancelled off as 3+2+1 don't equate to 360.
So, we have:
Oli's share = 3xSam's share = 2xTim's share = 1x = xTheir total evaluates to 360 (in euros).
(we don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)
Thus, we get:
\(3x + 2x + x = 360\\(3+2+1)x = 360\\6x = 360\\\\\text{Dividing both the sides by 6}\\\\\dfrac{6x}{6} = \dfrac{360}{6}\\\\x = 60\)
Thus, we get:
Oli's share = 3x = 3×(60) = £180Sam's share = 2x = 2×(60) = £120Tim's share = 1x = x = £60Thus, the amount that Sam get (the share of Sam) is £120

a) Suppose a set of 8 numbers are selected from the set{1,2,…,13,14}. Show that two of the selected numbers must sum to 15. b) There are 14 3-digit numbers in a list. Can you conclude that there are two distinct subsets of the 14 numbers that have the same sum? Justify your answer.
a. There must be two selected numbers that sum to 15.
b. We cannot guarantee that there are two distinct subsets with the same sum in this case.
What is Pigeonhole principle?According to the pigeonhole principle, at least one container must have more than one item if n things are placed into m containers, where n > m.
(a) To show that two of the selected numbers must sum to 15 from a set of 8 numbers chosen from {1, 2, ..., 13, 14}, we can use the Pigeonhole Principle.
We have 14 numbers in the set {1, 2, ..., 13, 14}, and we need to select 8 numbers from this set. The possible sums of any two numbers from this set range from a minimum of 1 + 2 = 3 to a maximum of 13 + 14 = 27.
Since we have 8 selected numbers but only 7 possible sums (3, 4, ..., 10, 11, 12, 13), by the Pigeonhole Principle, at least two of the selected numbers must have the same sum. The only sum that is missing from the possible sums is 15. Therefore, there must be two selected numbers that sum to 15.
(b) In the case of 14 3-digit numbers in a list, we cannot conclude that there are two distinct subsets of the 14 numbers with the same sum. This is because the range of possible sums for two distinct 3-digit numbers ranges from a minimum of 100 + 100 = 200 to a maximum of 999 + 998 = 1997.
Since the range of possible sums (200 to 1997) exceeds the number of distinct subsets of the 14 numbers (2¹⁴ = 16,384), it is possible for each subset to have a unique sum. Therefore, we cannot guarantee that there are two distinct subsets with the same sum in this case.
