Point P partitions the directed line segment from A to B into the ratio 3:4. Will P be closer to A or B? Why
Final answer:
Point P will be closer to B than to A because the ratio of the partition is 4/7 which is closer to B than the ratio of 3/7 to A.
Explanation:
To determine whether point P will be closer to A or B, we need to consider the ratio of the partition. In this case, the ratio is 3:4. This means that the segment from A to P is 3/7 of the total segment, and the segment from P to B is 4/7 of the total segment.
Since the ratio of the partition is closer to B (4/7) than to A (3/7), point P will be closer to B than to A.
For example, if the distance from A to B is 7 units, the distance from A to P will be 3 units (3/7 * 7) and the distance from P to B will be 4 units (4/7 * 7).
If point P partitions the directed line segment from A to B into the ratio 3:4, then P will be closer to A. The ratio 3:4 means that the segment AP is 3 parts long while segment PB is 4 parts long, making PB longer than AP. The entire segment AB is therefore divided into 7 equal parts, with point P falling 3/7 of the distance from A and 4/7 from B. Since 3/7 is less than 4/7, P is closer to A.

10. George, Sandy, Carlos, and Michelle all ate a piece of a whole
pecan pie. George ate 0.15 of the pie, Michelle ate of the pie,
and Carlos ate of the pie. Sandy ate more than two of her
friends, but less than the other one. What is a possible
percentage of the ple Sandy ate?
Answer:
0.150 < (Proportion of Sandy's pie) < 0.167
15% < (Percentage of Sandy's pie) < 16.7%
Step-by-step explanation:
Total percentage of pie = 100% or 1
George, Sandy, Carlos, and Michelle all ate a piece of the pie.
George ate a fraction of 0.150
Michelle ate a fraction of (1/6) = 0.167
Carlos ate a fraction of (1/7) = 0.143
The amount of pie left = 1 - 0.15 - (1/6) - (1/7) = 0.5405
And Sandy is known to eat more than two of her friends, but less than one of them.
Of the amount of pie eaten by the first 3 friends, (1/6) is the highest proportion.
Hence, it is evident that Sandy ate more than 0.143 and 0.150 (Carlos and George) but less than Michelle (0.167).
So, mathematically, the possible proportion of cake that Sandy ate is
0.150 < (Proportion of Sandy's pie) < 0.167

find the value of c so that (x+2) is a factor of the polynomial p(x). p(x)=4x^3+cx^2+x+2
Answer:
c = 8
Step-by-step explanation:
Use synthetic division here; it's the fastest approach.
Given that (x + 2) is a factor, take -2 and use this as the divisor in synthetic division:
-2 4 c 1 2
-8 (-2c+ 16) (4c-34)
---------------------------------------------
4 (c - 8) (-2c + 17) 4c - 32
The remainder, 4c - 32, must equal zero if (x + 2) is a factor.
Then 4c - 32 = 0, and c = 8

Which graph represents the circle (x + 2)2 + (y - 3)2 = 25?
Answer:
the center is (-2,3)
Step-by-step explanation:
The required graph that represents circle (x + 2)² + (y - 3)² = 25 is given below in the image.
graph represents the circle (x + 2)2 + (y - 3)2 = 25 to determine.
The area of the circle is given by the pie times square of the radius.
Area of circle = πr^2
Standard form of the equation of circle = ( x - h ) ²+ ( x - y )² = r²
Where r is the circle's radius and h and k is the circle's center.
Given equation of the circle = (x + 2)² + (y - 3)² = 25
where center is ( -2, 3 )
radius r = √25 = 5
While plotting a circle on a graph marks the center at ( -2, 3 ) radius. and draw the circle of radius 5 around the center ( -2, 3 ). The result is shown in the image.
Thus, the required graph that represents circle (x + 2)² + (y - 3)² = 25. is given below in the image.

What is the greatest common factor of 4x^3
and 8x^2?
Answer:
the gcf is 4
Step-by-step explanation:
Final answer:
To find the greatest common factor of 4x³ and 8x², we look at the numerical coefficients and the variables separately. The GCF of the coefficients 4 and 8 is 4, and since x² is the lowest power of x common in both terms, the GCF is 4x².
Explanation:
The greatest common factor (GCF) of two expressions, like 4x³ and 8x², involves finding the highest degree of common terms they share. First, let's compare the numerical coefficients; 4 and 8. The GCF of 4 and 8 is 4. Next, we'll look at the variable part. The lowest exponent of x that appears in both terms is 2. Therefore, the GCF is the product of the GCF of the coefficients and the lowest power of x, which is 4x².

Which value of b would make x²+bx-30 factorable?
A. -31
B. -17
C. 11
D. 13
Answer:
D. 13
Step-by-step explanation:
well since it's a quadratic equation, it can be written in the form of ax²+bx+c=0. So we have a=1, b=b and c= -30. Also the roots are given by the equation-
x= -b±[tex]\sqrt{b^{2}-4ac}[/tex] /2a. So all I did was put the number from the choices which would satisfy the sqrt part and that turned out to be 13 since [tex]\sqrt{13^{2}-4*1*(-30)[/tex] = [tex]\sqrt{289}[/tex] = 17. So b=13.

When working with rational expressions, restricted values are values of your variable that results in an undefined rational expression. Given the following rational expressions: 2x+4/x^2−x−6 and 2/x−3 Determine whether the rational expressions are equivalent and explain your answer. Determine the values that would make the rational expressions undefined. Are these values the same or different? Explain.
Answer:
See below
Step-by-step explanation:
2x+4 / x^2-x-6
= 2(x+2)/(x-3)(x+2)
= 2/(x-3)
So the 2 expressions are equivalent
The values of x which make the expressions undefined are those values which make the denominators 0
For 2x+4/ x^2-x-6 they are X=3 and x= -2.
For 2/x-3 they are x =3.

A knitting pattern for a shawl calls for 8
stitches in the first row. Each row after that
has 2 more stitches than the previous row.
The explicit rule ax = 8 + (k − 1)2 gives the
number of stitches in the nth row row.

In the diagram below, point U is on segment $\overline{BY}$ and the measure of angle BUG is 30 degrees greater than the measure of angle GUY:
Answer: 75
Step-by-step explanation:
We have angle BUG angle GUY = angle BUY = 180. If we let angle GUY = x, then
(x+30) + x = 180 Solving this equation gives x=75.
Using the definition of linear pair angles, the measure of angle GUY is: 75°.
What is a Linear Pair?A linear pair are two angles on a straight line whose sum equals 180 degrees.
Thus:
m∠BUG = m∠GUY + 30°
Therefore:
m∠BUG + m∠GUY = 180°
Substitute
m∠GUY + 30 + m∠GUY = 180 (linear pair)
2(m∠GUY) + 30 = 180
2(m∠GUY) = 180 - 30
2(m∠GUY) = 150
m∠GUY = 150/2
m∠GUY = 75°
Therefore, using the definition of linear pair angles, the measure of angle GUY is: 75°.

A circular plate has circumference 23.9 inches. What is the area of this plate?
Answer:
Rounded to the nearest thousandth: ≈45.479
Step-by-step explanation:
The formula for finding area using circumference is
[tex]\frac{c^2}{4\pi }[/tex]
c=23.9"
[tex]\frac{23.9^2}{4\pi }[/tex]
Since we're using 3.14 for pi, multiply 4 by 3.14, and continue from there.
[tex]\frac{23.9^2}{4(3.14)} = \frac{571.21}{12.56} = 45.47850318[/tex]
but we don't use that big number! We round to the nearest thousandth!
≈45.479
Answer:
46 inches^{2}
Step-by-step explanation:
The formula for the area of a circle is [tex]\pi r^{2}[/tex]
To work this out you would first need to divide 23.9 by pi to find out diameter.
Then you would divide the diameter by 2 to find the radius. Then you would multiply pi by the radius squared.
1) Divide 23.9 by [tex]\pi[/tex].
[tex]23.9/\pi=7.608[/tex]
2) Divide 7.608 by 2.
[tex]7.608/2=3.804[/tex]
3) Multiply pi by the radius squared.
[tex]\pi *3.804^{2} =45.4601526[/tex]

Step-by-step explanation:
1.5x + 5y = 1152
x = 4y – 2
We can substitute the second equation into the first equation
Which one-variable linear equation can be formed using the substitution method?
1.5(4y-2) +5y = 1152
Distribute
