Answer:
x = 5, x = 7
Step-by-step explanation:
to find the zeros let f(x) = 0 , that is
x² - 12x + 35 = 0 ( subtract 35 from both sides )
x² - 12x = - 35
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 6)x + 36 = - 35 + 36
(x - 6)² = 1 ( take the square root of both sides )
x - 6 = ± [tex]\sqrt{1}[/tex] = ± 1 ( add 6 to both sides )
x = 6 ± 1
then
x = 6 - 1 = 5
x = 6 + 1 = 7
Since spring started, Kareem has been surveying the growth of leaves on his neighborhood trees. He goes out every day and computes the average number of leaves on a sample of trees. He created a scatter plot where the y-axis represents the average number of leaves on the trees, and the x-axis represents the number of weeks since spring started. Use the 2 given points to write a linear equation that can be used to approximate the data distribution.
Answer:
y = 1566.67x + 1716.67
is the actual answer..
The linear equation that can be used to approximate the data distribution is y = 1566.67x + 1716.67.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Linear equations may include one or more variables.
Given two points on the line.
(0.5, 2500) and (3.5, 7200)
Slope intercept form of a linear equation is y = mx + c, where m is the slope and c is the y intercept.
Slope = (7200 - 2500) / (3.5 - 0.5)
= 4700 / 3
= 1566.67
So the equation is, y = 1566.67x + c
Substitute the point (0.5, 2500) to the equation.
2500 = (1566.67 × 0.5) + c
c = 1716.67
So the equation is, y = 1566.67x + 1716.67
Hence the required equation is y = 1566.67x + 1716.67.

Find each real root.
Answer:
Step-by-step explanation:
I'm assuming the 7 is the question number.
The cube root is -2. There is only 1 real root.
You could find it this way. ∛(-8) = ∛-2 * - 2 * - 2
The rule for cube roots when the number has 3 roots that are the same is to take one outside the ∛ sign and discard the other 2.

If a single card is drawn from a standard 52-card deck, what is the probability it is a diamond or a face card (Jack, Queen, or King)?
A. 11/26
B. 2/7
C. 1/4
D. 2/52
Using it's concept, it is found that the probability that the card is a diamond or a face card is given by:
D. 25/52
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
A standard deck has 52 cards, of which 13 are diamond and 12 are face, hence:
p = (13 + 12)/52 = 25/52.
Which means that option D(25/52) is correct.

what is the equation of the line that hasthe solution "-2" and 4
Answer:
First you need to find the slope: (y2 - y1)/(x2 -x1) = (-4 -(-4))/(0-2) = 0. So the line is horizontal, which means the y coordinate is constant and equal to -4, so the equation of the line is y = -4.
Step-by-step explanation:
since both points have a y value of -4 you could have jumped directly to y = -4

Find the area of the given triangle. Round your answer to the nearest tenth.
A right triangle with a base of 36. The angle of elevation is 25 degrees.
Group of answer choices
302.2 units squared
1 comma 389.6 units squared
766.6 units squared
Using relations in a right triangle, it is found that it's area is of 302.2 units squared.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.In this problem, we have that the opposite side to the angle of 25º is of x, while the adjacent side is of 36, hence:
[tex]\tan{25^\circ} = \frac{x}{36}[/tex]
[tex]x = 36\tan{25^\circ}[/tex]
x = 16.79.
What is the area of a right triangle?It is given by half the multiplication of it's sides, hence:

Tyler bought a wedge. He measured the arc length of the wedge to be 12 centimeters and the radius to be 8 centimeters. Priya bought a wedge that came from a circular cheese block with radius 9 centimeters. The block was cut into 6 congruent sectors. Whose wedge is larger? Explain or show your reasoning.
The wedge is an illustration of arc lengths, and Tyler's ledge is larger than Priya's wedge
How to determine the larger wedge?From the question, the arc length of Tyler's wedge is:
L = 12 cm
For Priya's wedge, we have the following highlights:
Radius = 9 cm
Angle = 60 degrees i.e. the angle when a circle is divided into 6 sectors
Priya's arc length is then calculated as:
[tex]L = \frac{\theta}{360} * 2\pi r[/tex]
This gives
[tex]L = \frac{60}{360} * 2 * 3.14 * 9[/tex]
Evaluate
L = 9.42
By comparing the arc lengths 9.42 and 12 cm, we have 12 cm > 9.42 cm
Hence, Tyler's ledge is larger than Priya's wedge

Answer:
Triangle - 17.5
Trapezoid - 64
Step-by-step explanation:
Triangle - This is because the triangle formula is h x b/2 and H is 7 and B is 5 so 5 x 7 is 35 divided by 2 is 17.5.
Trapezoid - a + b/2 times h and A is 6, B is 10 and H is 8 so 6+10 = 16 and 16/2 equals 8 and 8 x 8 =64.

Answer:
D
Step-by-step explanation:
Consecutive integers are integers with the progression n, n+1, n+2 (EXAMPLE)
Since w, x, y are consecutive integers, that means w, w+1, w+2; x = w+1, y = w+2
By referring to D,
w + x + y = w + w+1 + w+2
= 3w + 3
Hence, D is true.
Answer:
D
Step-by-step explanation:
A is wrong because if w is -1, x is 0, and y is 1, then wy is negative.
B is wrong because if w is -1, x is 0, and y is 1, then -1 + 1 = 0, which is x.
C is wrong because if w is -1, x is 0, and y is 1, then w³ + 3 = -1 + 3 = 2, which is greater than w + x + y which is 0.
D is correct because w + x + y is always equal to 3w + 3. For example, if w is 1, x is 2, and y is 3, then w + x + y = 6. 3w + 3 = 3(1) + 3 = 6.
E is wrong because if w is 1, x is 2, and y is 3, then wx is 2 and xy is 6, which means xy is greater than wx.
