Answer:
Step-by-step explanation:
Rewrite this in standard quadratic equation form: x^2 - 7x + 6 + 8 = 0, or x^2 - 7x + 14 = 0. This does not factor easily, so I will use the quadratic formula to find the roots and then write out the factors based upon the roots:
The discriminant is b^2 - 4ac, which here is (-7)^2 - 4(1)(14) = -7.
Because the discriminant is negative, we know that there are two unequal, complex roots. They are:
-(-7) ± i√7 7 ± i√7
x = ----------------- = ---------------
2 2
One factor is (x - [1/2]{7 ± √7} )

At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.
Answer:
20.2 m
Step-by-step explanation:
At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.
We solve this question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = 34°
Adjacent =30m
Opposite = Height of the flag pole = x
Hence
tan 34 = x/30
Cross Multiply
tan 34 × 30m
= 20.235255505 m
Approximately = 20.2 m
Hence, the height of the flag pole to the nearest meter = 20.2m

Solve for b.
-3b+2.5 = 4
Answer:
b = −0.5
Step-by-step explanation:
Let's solve your equation step-by-step.
−3b+2.5=4
Step 1: Subtract 2.5 from both sides.
−3b+2.5−2.5=4−2.5
−3b=1.5
Step 2: Divide both sides by -3.
-3b/-3 = 1.5/-3
The value of 'b' in the equation given is -0.5
Given the expression for which we could solve for the unknown:
-3b + 2.5 = 4Subtract 2.5 from both sides
-3b = 4 - 2.5
-3b = 1.5
divide both sides by -3 to isolate b
-3b/-3 = 1.5/-3
b = -0.5
Therefore, the value of b in the equation given is -0.5

(2,4)=2+4=6 (5,4) =5+4 =9
(2,5)=2+5=7 (5,5)=5+5=10
(2,6)=2+6=8 (5,6)=5+6=11
(3,1)=3+1=4 (6,1)= 6+1=7
(3,2)=3+2=5 (6,2)=6+2=8
(3,3)=3+3=6 (6,3)=6+3=9

Analyze the diagram below and complete the instructions that follow.
Find m
Answer:
D. 70.53
Step-by-step explanation:
To solve this problem, one must use the right angle trigonometric rations. These ratios can be used to describe the ratio between the sides and an angle in a right triangle. Please note, each side is named relative to the angle that one is looking at, thus the same side can acquire different names based on the angle one uses to describe it. The trigonometric ratios are the following:
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
In this case, one is asked to find the measure of (<CBA), one is given the hypotenuse (the side opposite the right angle), and the side adjacent to this angle. Therefore, one should use the cosine (cos) function to find this angle.
[tex]cos(\theta)=\frac{adjacent}{hypotenuse}[/tex]
Substitute,
[tex]cos(CBA) = \frac{3}{9}[/tex]
Simplify
[tex]cos(CBA) = \frac{1}{3}[/tex]
Inverse operations,
[tex]CBA=cos^-1(\frac{1}{3})[/tex]
Compute,
m<CBA = 70.53

Kalo randomly surveyed 25 students at his school and found that 19 of them have at least one sibling. Based on these data, how many of the 125 students at his
school would be expected to have at least one sibling?
Answer:
95 students
Step-by-step explanation:
25 students -- 19 have sibling
1 student -- (19/25)
125 students -- (19/25) * 125 = 95
Therefore, 95 students out of 125 are expected to have at least one sibling.
Thenks and mark me brainliest :))
Answer:
95
Step-by-step explanation:
Calculate the experimental probability of choosing a student who has at least one sibling: It is 19/25, or 0.56.
If 125 students are selected, this probability applies. Multiply 125 by 0.56:
0.56(125 students) = 95
95 students could be expected to report having at least one sibling.

A rectangular tank measures 16 cm by 9 cm by 10 cm. How many milliliters of water are in the tank when it is full? How many liters?
Answer:
1,440 cubic centimeter = 1,440 milliliters
1,440 cubic centimeter= 1.44 liters
Step-by-step explanation:
Volume of the rectangular tank = length × width × height
Length = 16 cm
Width = 9 cm
Height = 10 cm
Volume of the rectangular tank = length × width × height
= 16 cm × 9 cm × 10 cm
= 1,440 cm³
Volume of the rectangular tank = 1,440 cm³
How many milliliters of water are in the tank when it is full?
1 cubic centimeter = 1 milliliter
1,440 cubic centimeter = 1,440 milliliters
How many liters?
1 cubic centimeter = 0.001 liters
1,440 cubic centimeter= 1.44 liters
Find the 8th Term for the Geometric Sequence for which a1 - 3 and r = -2
Answer:
-384
Step-by-step explanation:
geometric sequence : every new element is generated by multiplying the previous element always with the same number r.
a(n) = a(n-1) * r
a(n) = a(1) * r^(n-1)
so, a(1) = 3, r = -2
a(8) = ?
a(8) = a(1) * r^7 = 3 * (-2)^7
a negative number to an uneven power is again a negative number.
so, (-2)^7 = -128
3 * -128 = -384 = a(8)
Solve for y:
x + 2y = -8
y=-1/2x+4
y=-1/2x-4
y=-2x - 4
y=1/2x-4
Answer:
x + 2y = -8 = y = -4 - 1/2x
y= -1/2x + 4 = y = 4
y= -1/2x - 4 = y = -4
y=-2x - 4 = y = -4
y=1/2x-4 = y = -4
Step-by-step explanation:
(x + 2y = -8 = y = -4 - 1/2x)
[tex]x+2y=-8\\2y=-8-x\\y=-4-\frac{1}{2}x\\[/tex]
