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

The angle of elevation of a car to the top of a tree is 60°. If the height of the tree is 34 feet, find the distance between the car and the tree rounded to the nearest whole number.
Answer:
17 feet
Step-by-step explanation:
cos = adj/hyp
cos60 = adj/34
34 * cos60 = adj
adj = 17
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
How to find (fg)(x) from the equation
Calculate the following
S2+54+18+46+237
Note that you can make the work very easy by being smart in deciding how to
group the operations
Answer:
S2 + 355
Step-by-step explanation:
Given the expression to evaluate :
S2+54+18+46+237
Since the values are bound by the addition operator, we take the sum of the like terms ;
S2 + (54+18+46+237)
S2 + 355

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

Answer:
2/5
Step-by-step explanation:

-4/-102/5Solve the equation -3h + 6 = -15 for h.
Answer:
h = 7
Step-by-step explanation:
-3h + 6 = -15
Get rid of the 6 by subtracting it from both sides.
-3h + 6 - 6 = -15 - 6
-3h = -21
Get rid of the -3 by dividing it from both sides.
-3h/-3 = -21/-3
h = 7

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

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

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]

Which of the following represents an image of △LMN under a dilation with a scale factor of 14/?
HELP ME NOW!! RED IS THE ONE I GOT WRONG!
Answer:
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
Dilation is the increase or decrease in size of a figure by a factor k. If k > 1, then the dilation is an increase whereas if k<1, then the dilation is a decrease.
From the diagram, since triangle LMN is dilated by a factor of 1/4, hence the size of LMN is reduce. Therefore:
L'M' = (1/4)LM, L'N' = (1/4)LN, N'M' = (1/4)NM
Also, the distance from point P to N' is one-fourth of the distance from point P to N.
The correct option is highlighted in the image attached.
