Answer:
5.455Step-by-step explanation:
If the password for a certain safe is indicated by multiplying (x^2-16)/(x-1) with 1 / ((x ^ 2 + 6x + 8) / (x ^ 2 + 2x-3))
Simplify the expression in its lowest term first
[tex]= \dfrac{x^2-16}{x-1} * \dfrac{1}{\dfrac{x ^ 2 + 6x + 8}{x ^ 2 + 2x-3} } \\\\= \dfrac{x^2-16}{x-1} * }{\dfrac{x ^ 2 + 2x - 3}{x ^ 2 + 6x + 8} }\\\\= \dfrac{ (x+4)(x-4)}{x-1} * \dfrac{(x+3)(x-1)}{(x+4)(x+2)}\\\\= \dfrac{x-4}{1} * \dfrac{x+3}{x+2}\\[/tex]
If the value of x = 9, to get the numeric value of the password, we will substitute x = 9 into the resulting function as shown;
[tex]= \dfrac{x-4}{1} * \dfrac{x+3}{x+2}\\\\= \dfrac{9-4}{1} * \dfrac{9+3}{9+2}\\\\= \frac{5}{1} * \frac{12}{11}\\\\= \frac{60}{11}\\ \\= 5.455[/tex]
Hence the numeric value of the password is 5.455

[tex]BC=40[/tex]
Step-by-step explanation:
Since AC is a tangent and PB is the raduis
[tex]\angle PBC= 9[/tex]
By pythagoras
[tex]PC^{2} =PB^{2} +BC^{2}[/tex]
[tex]41^{2} =9^{2} +BC^{2}[/tex]
[tex]1681-81=BC^{2}[/tex]
[tex]1600=BC^{2}[/tex]
[tex]BC=\sqrt{1600}[/tex]
[tex]BC=40[/tex]
OAmalOHopeO
Answer:
40
Step-by-step explanation:
A tangent to a circle is perpendicular to the radius intersection by definition. That makes BPC a right triangle at B. BP and PD are both equal (9) because every radius of a circle is equal. So
PC**2 = BP**2 + BC**2 or
41**2 = 9**2 + BC**2
1681 = 81 + BC**2
1681 - 81 = BC**2
1600 = BC**2
40 = BC

Find the equation of a circle with PQ as diameter, where P(2,-6) and Q(-6,-4)
Answer:
y=-¼x+⁴⁴/8
Step-by-step explanation:
p(2,-6). Q(-6-4)
p (x¹,y¹). Q(x²,y²)
1) find the gradient(slope)
gradient=y²-y¹
x²-x¹
gradient = -4-(-6)
-6-2
gradient= -4+6
-6-2
gradient=²/-8
2)equation is supposed to be in the form of y=mx+c
where m is the gradient
thus.
gradient=y²-y¹
x²-x¹
when finding the equation we only use one of the values of the coordinates leaving the other as an unknown value.
2 = y-(-4)
-8 x-(-6)
2 =y+4
-8. x+6
remove the denominators by cross multiplying that is:
2(x+6)= -8(y+4)
2x+12= -8y-32
express in the format y=mx+c
2x+12+32=-8y
2x+44=-8y.
divide all sides by -8 to remain with y
²/-8x+⁴⁴/-8=y
-¼x+ -⁴⁴/8=y
y=-¼x-⁴⁴/8

A library building is in the shape of a rectangle. Its floor has a length of (3x + 5) meters and a width of (5x − 1) meters. The expression below represents the area of the floor of the building in square meters: (3x + 5)(5x − 1) Which of the following simplified expressions represents the area of the floor of the library building in square meters? (5 points)
Answer:
(16x + 8)m²
Step-by-step explanation:
area of a rectangle = 2length + 2width
=2(3x + 5) + 2(5x-1)
=6x + 10 + 10x - 2
=(16x + 8)m²
Use the diagram below to answer the questions. Line q contains points J, K, and M. Point P is above line q between points K and M. A line connects points M and P. Another line connects points P and K. Point L is above point J. A line starts at point K and extends through point L. Which are shown on the diagram? Check all that apply. Line segment J L Ray K M Line J K Ray P K AngleLJK Ray M J
Answer:
2nd 3rd last one
Step-by-step explanation:
Angles, lines, rays, and segments can be found in a plane. The terms shown on the diagram are: Ray KM, Line JK, and Ray MJ
What are lines, rays, and segments?A line is an unending, straight path that has no endpoints and travels in both directions along a plane. A line segment is a finitely long portion of a line with two endpoints. A line segment that goes on forever in one direction is known as a ray.
To identify the terms shown on the diagram, we need to note the following: A ray has no endpoint; it is represented with an arrow on one side line segment has two endpoints.
It is represented with dots on both sides. An angle is a space between intersecting lines, line segments, or rays. There is no connection between J and L. So, JL is not a line segment
Ray KM
KM has a dot at point K and an arrow that points in the direction of M. So, KM is a ray.
Line JK
JK has dots on both ends (at J and K). So, JK is a line.
Ray PK
PK has dots on both sides (at P and K). So, PK is a line; not a ray.
Angle LJK
There is no connection between points L, J, and K. Hence, LJK is not an angle.
Ray MJ
MJ has a dot at point M and an arrow that points in the direction of J. So, MJ is a ray.
The diagram is attached with the answer below.

Jack picks 3 liters of berries in 8 minutes. Jill picks 4 liters of berries in 10 minutes. Working together, how many berries can they pick in 1 minute?
Answer:
they can pick 27 berry's
Step-by-step explanation:
I think-
They can pick 1.29 liters of berries in 1 minute working together.
--------------------------------------------
The together rate is the sum of each separate rate. In this question:
We want to find the together rate.Jack's rate is [tex]\frac{3}{8}[/tex]Jill's rate is [tex]\frac{4}{10}[/tex]--------------------------------------------
Together, they can pick x liters, and the rate is: [tex]\frac{1}{x}[/tex]
Then
[tex]\frac{1}{x} = \frac{3}{8} + \frac{4}{10}[/tex]
[tex]\frac{1}{x} = \frac{15 + 16}{40}[/tex]
[tex]\frac{1}{x} = \frac{31}{40}[/tex]
Applying cross multiplication:
[tex]31x = 40[/tex]
[tex]x = \frac{40}{31}[/tex]
[tex]x = 1.29[/tex]
They can pick 1.29 liters of berries in 1 minute working together.

An agriculture company is testing a new product that is designed to make plants grow taller. This can be thought of as a hypothesis test with the following hypotheses.H0: The product does not change the height of the plant.Ha: The product makes the plant grow taller.Is the following an example of a type I or type II error?The sample suggests that the product makes the plant grow taller, but it actually does not change the height of the plant.a) Type Ib) Type II
Answer:
The error made here is a Type I error.
Step-by-step explanation:
A Type I error is the rejection of a null hypothesis (H₀) when indeed the null hypothesis is true. It is symbolized by α.
A Type II error is failing to discard a null hypothesis when indeed the null hypothesis is false. It is symbolized by β.
The hypothesis in this case is defined as follows:
H₀: The product does not change the height of the plant.
Hₐ: The product makes the plant grow taller.
The sample suggests that the product makes the plant grow taller, but it actually does not change the height of the plant.
So, the sample suggests to reject the null hypothesis when in fact the null hypothesis is true.
Thus, the error made here is a Type I error.

Answer:
Step-by-step explanation:
measure of a = 9 degree
angle POM = 48 degree = angle NMO [ AIA}
HOPE IT HELPS
Answer:
Below
Step-by-step explanation:
We are given that <PMO= (3a+15)° and NMO= (6a-6)°
Notice that the sum of <PMO and <NMO gives a right angle.
● <PMO+<NMO = 90°
● 3a+15+6a-6 = 90
● 9a + 9 = 90
Substruct 9 from both sides
● 9a +9 -9 = 90 -9
● 9a = 81
Divide both sides by 9
● 9a/9 =81/9
● a = 9
So the value of a is 9°
■■■■■■■■■■■■■■■■■■■■■■■■■■
MN and PO are parallel since MNOP is a rectangle.
MO is crossing MN and PO so <POM and < NMO are alternate interior angles wich means that they have the same size.
● <NMO = <POM
● <POM = 6a-6
The value of a is 9°
● <POM = 6*9-6 = 48°
So <POM = 48°

A basketball is shot into the air. Its height is represented by the polynomial equation h(t) = –16t2 + 35t + 5, where h is the height of the basketball at t seconds. What's the height of the basketball at 1.5 seconds?
Question 4 options:
20.2 feet
18.8 feet
21.5 feet
16.7 feet
Answer:
height = 21.5 ft
Step-by-step explanation:
Substitute t = 1.5 into h(t) and evaluate
h(1.5) = - 16(1.5)² + 35(1.5) + 5
= - 16(2.25) + 52.5 + 5
= - 36 + 57.5
= 21.5 ft
Answer:
21.5 feet.
Step-by-step explanation:
Let t = 1.5
[tex]h(1.5)=-16(1.5)^2+35(1.5)+5\\h(1.5)=-36+52.5+5\\h(1.5)=21.5[/tex]
Therefore, at 1.5 seconds, the basketball is 21.5 feet in the air.
Solve for u.

Simplify your answer as much as possible.
Step-by-step explanation:
- 22 = -8u + 6(u-7)
-22 = -8u + 6u - 42
8u - 6u = 22 - 42
2u = -20

Multiply this amount by the principal amount, 880.
880*0.26=228.8 is 26% of 880
Answer:
26% of 880

Answer:
.............................
Given that A is directly proportional to B and that A = 5/3 when B = 5/6, find A when B=1/3 and B when A =15/2.
Step-by-step explanation:
A is directly proportional to B is written as
A = kBwhere k is the constant of proportionality
First we must find the relationship between the two variables
when
A = 5/3
B = 5/6
Substitute the values into the formula to find k
[tex] \frac{5}{3} = k \frac{5}{6} [/tex]
Multiply through by the LCM which is 6
That's
[tex]5 \times 2 = 5k[/tex]
5k = 10
Divide both sides by 5
k = 2
So the formula for the variation is
A = 2Bwhen B = 1/3
[tex]A = 2 \times \frac{1}{3} [/tex]
[tex]A = \frac{2}{3} [/tex]When A = 15/2
[tex] \frac{15}{2} = 2B[/tex]
Multiply through by 2
[tex]4B = 15[/tex]
Divide both sides by 4
[tex]B = \frac{15}{4} [/tex]Hope this helps you
