Answer:
k = - 18
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 2
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, - 12) and (x₂, y₂ ) = (6, k)
m = [tex]\frac{k+12}{6-3}[/tex] = [tex]\frac{k+12}{3}[/tex] = - 2 ( multiply both sides by 3 )
k + 12 = - 6 ( subtract 12 from both sides )
k = - 18
For the given table of values for a polynomial function, where must the zeros of the function lie?
A. between 3.0 and 3.5 and between 4.0 and 4.5
B. between 3.5 and 4.0 and between 4.0 and 4.5
C. between 4.0 and 4.5 and between 4.5 and 5.0
D. between 3 .5 and 4.0 and between 4.0 and 4.5
E. between 3 .5 and 4.0 and between 5.0 and 5.5
Answer:
A. Between 3.0 and 3.5 and between 4.0 and 4.5
Step-by-step explanation:
The zeroes of a function occur whenever a value of x returns zero. To predict where the zeroes lie, determine the interval(s) where the function crosses the x-axis. This occurs when either [tex]f(x)[/tex] goes from a negative value to a positive value or vice versa.
From [tex]x=3.0[/tex] and [tex]x=3.5[/tex], the y-values go from 4.0 (positive) to -0.2 (negative), respectively. Therefore, there must be a zero in this interval.
From [tex]x=4.0[/tex] and [tex]x=4.5[/tex], the y-values go from -0.8 (negative) to 0.1 (positive), respectively. Therefore, there must also be a zero in this interval.
Thus, the zeros of this function occur between 3.0 and 3.5 and between 4.0 and 4.5, leading to answer choice A.
Answer:
between 3.0 and 3.5 and between 4.0 and 4.5

A kite string is 35m long. The angle the string makes with the ground is 50o
.
How far from the person holding the string is a person directly under the kite?
Answer:
22.50m
Step-by-step explanation:
With the ground, the horizontal ground distance is the adjacent side, so by SOHCAHTOA, the ratio used is cosine, i.e.
Ground distance
= hypotenuse * cos(50°)
= 35 cos(50°)
= 35*0.64279
= 22.50m

new community center. How I Find the prime factorization of the number 24
Answer:
2*2*2*3
or
2^3 * 3
Step-by-step explanation:
24 = 4*6
But 4 and 6 aren't prime
24 = 4*6 = (2*2) * (2*3)
All these numbers are prime
24 = 2*2*2*3 or with exponents = 2^3 * 3

How to find (fg)(x) from the equation
solve the simultaneous linear algebra quadratic equation 2x-y=8 3x-y=17
Answer:
2x-y=8
(3x-y=17)*_1
2x-y=8
-3x+y=-17
#-x=-9, x=9 & y=-10
Answer:
x = 9 and y = 10
Step-by-step explanation:
Subtract the second equation from 1 as in doing so the y will get cancelled as they are of the opposite sign.
2x - y = 8
-3x + y = -17
-----------------
- x = - 9
Therefore,
x = 9
Now we will add the value of x to any of the equation from the question.
2x - y = 8
2(9) - y = 8
18 - y = 8
Therefore,
y = 10

What is the approximate volume of the composite figure? Use 22/7 for pi. Round to the nearest hundredth. Enter your answer in the box.
Answer:
188.57 cm³
Step-by-step explanation:
Half sphere = 1/2 volume sphere
Sphere = 4/3 * 22/7 * 3³
Sphere = 4/3 * 22/7 * 27/1
Sphere = 2376/21 = 113.14
113.14 / 2 = 56.57
Cone = 22/7 * 3² * h/3
Cone = 22/7 * 9/1 * 14/3
Cone = 2772/21 = 132
132 + 56.57 = 188.57 cm³

9
Answer:
Step-by-step explanation:
I'm assuming that you are solving for x, since there's nothing else you can do with this mathematically.
[tex]\frac{1}{2}x=-9[/tex] and the goal is to get the x all alone. So we have to lose the fraction. Do that by multiplying by the reciprocal of 1/2 which is 2/1 (a reciprocal is just a fraction flipped upside down). BUT...because this is an equation, what you do to the left side has to be done to the right side too. Like this:
[tex](\frac{2}{1})\frac{1}{2}x=\frac{-9}{1}(\frac{2}{1})[/tex]
On the left, everything cancels out but the x (which is why we do this), and on the right we multiply straight across the top and straight across the bottom to get
[tex]x=\frac{-18}{1}[/tex] which is
x = -18

Which of these is coterminal with an angle in standard position that
measures 140°?
-40 degree
-500 degree
-220 degree
-60 degree
Answer:
Since the angle 140° is in the second quadrant, the reference angle formula is Ar=180°−Ac. A r = 180 ° - 140 = 40°

A bag contains 2 red, 4 blue, and 4 yellow marbles. What is the probability of pulling a red marble, putting the marble back, and then pulling a blue marble?
Answer:
Red: 1/5 or 0.2 or 20% (depends if the question asked you to give the answer in fraction/decimal/percentage. Either way, it's still correct)
Black: 0
Blue: 2/5 or 0.4 or 40%
Step-by-step explanation:
In total, the bag contains 10 balls,
2 are Red = 2/10 = 1/5There are no black marbles so you have 0 chance of pulling them out.4 are blue = 4/10 = 2/5

express fractions below having equal denominators: a) 2/5, 7/10, 9/40. b) 17/25, 23/40, 67/120
Answer:
Step-by-step explanation:
a) 5 = 5
10 = 2 * 5
40 = 2 * 2 * 2 *5
Least common denominator = 2*2*2*5=40
Now find equal fractions with denominator 40
[tex]\frac{2}{5}=\frac{2*8}{5*8}=\frac{16}{40}\\\\\frac{7}{10}=\frac{7*4}{10*4}=\frac{28}{40}\\\\\frac{9}{40}[/tex]
Fractions with equal denominators:
[tex]\frac{16}{40} ; \frac{28}{40} ; \frac{9}{40}[/tex]
b) 25 = 5* 5
40 = 2 * 2 * 2 * 5
120 = 2 * 2 * 2 * 3 * 5
Least common denominator = 8*25*3=600
[tex]\frac{17}{25}=\frac{17*24}{25*24}=\frac{408}{600}\\\\\frac{23}{40}=\frac{23*15}{40*15}=\frac{345}{600}\\\\\frac{67}{120}=\frac{67*5}{120*5}=\frac{335}{600}\\\\[/tex]
