The value of log b to the nearest hundredth is 1.23. The correct option is the second option - 1.23
Evaluating logarithmFrom the question, we are to determine the value of log b to the nearest hundredth
From the given information
[tex]log_{5}b = log_{9}48[/tex]
But,
[tex]log_{9}48 =1.76186[/tex]
∴ [tex]log_{5}b =1.76186[/tex]
By one of the laws of logarithm
∴ [tex]b =5^{1.76186}[/tex]
b = 17.0407
Then,
log b = log(17.0407)
= 1.2315
∴ log b ≅ 1.23
Hence, the value of log b to the nearest hundredth is 1.23. The correct option is the second option - 1.23

Part c what are the dimensions of the rectangular prisms you identified in parts a and b? list dimensions for all your decompositions (sets of shapes).
previous:
part a
think about splitting this shape into rectangular prisms. what is the least number of rectangular prisms in which you can split the shape? answer: 3
part b
in how many different ways can you split the shape to get the same number of rectangular prisms you identified in part a?
answer: 2
The dimensions of the rectangular prisms are the side lengths of the rectangular prism
How to determine the dimensions?A rectangular prism has the following dimensions
Length, width and height
This means that the dimensions of the rectangular prisms are the length, width and height of the prism
To determine the dimension, we simply take the value of the above terms i.e. length, width and height
How to split the rectangular prism?To split the rectangular prism, we simply consider the faces of the rectangular prism.
A rectangular prism has 6 faces
Hence, there are 6 shapes when the rectangular prism is split

q9 pg 164 foundations of mathematics and pre-calculus 10
The time used for the first part of the trip in minutes is 270 minutes.
How to find the time used for the trip?Total distance travelled = 675 km
He travelled from 1pm to 9pm.
He rested for 1 hour 30 minutes. The total time used for the trip is 6 hours 30 minutes.
let
the time used for the first part of the trip = x
Therefore,
speed = distance / time
distance = 110x
the time used for the first part of the trip = 6.5 - x
distance = 90(6.5 - x)
distance = 585 - 90x
Hence,
110x + 585 - 90x = 675
20x + 585 = 675
20x = 675 - 585
20x = 90
x = 90 / 20
x = 4.5 hours = 270 minutes
Therefore, the time used for the first part of the trip is 270 minutes.

Using Rolle's theorem prove that the function has at most one root on the given interval [tex]f(x)=x^3-12x+11, [-2,2][/tex]
f(x) = _ at x = _ x = _
Answer:
Show that if [tex]f(a) = f(b) = 0[/tex] for some [tex]a,\, b \in [-2,\, 2][/tex] where [tex]a \ne b[/tex], then by Rolle's Theorem [tex]f^{\prime}(x) = 0[/tex] for some [tex]x \in (-2,\, 2)[/tex]. However, no such [tex]x[/tex] exists since [tex]f^{\prime}(x) < 0[/tex] for all [tex]x \in (-2,\, 2)\![/tex].
Note that Rolle's Theorem alone does not give the exact value of the root. Neither does this theorem guarantee that a root exists in this interval.
Step-by-step explanation:
The function [tex]f(x) = x^{3} - 12\, x + 11[/tex] is continuous and differentiable over [tex][-2,\, 2][/tex]. By Rolle's Theorem. if [tex]f(a) = f(b)[/tex] for some [tex]a,\, b \in [2,\, -2][/tex] where [tex]a \ne b[/tex], then there would exist [tex]x \in (a,\, b)[/tex] such that [tex]f^{\prime}(x) = 0[/tex].
Assume by contradiction [tex]f(x)[/tex] does have more than one roots over [tex][-2,\, 2][/tex]. Let [tex]a[/tex] and [tex]b[/tex] be (two of the) roots, such that [tex]a \ne b[/tex]. Notice that [tex]f(a) = 0 = f(b)[/tex] just as Rolle's Theorem requires. Thus- by Rolle's Theorem- there would exist [tex]x \in (a,\, b)[/tex] such that [tex]f^{\prime}(x) = 0[/tex].
However, no such [tex]x \in (a,\, b)[/tex] could exist. Notice that [tex]f^{\prime}(x) = 3\, x^{2} - 12[/tex], which is a parabola opening upwards. The only zeros of [tex]f^{\prime}(x)[/tex] are [tex]x = (-2)[/tex] and [tex]x = 2[/tex].
However, neither [tex]x = (-2)[/tex] nor [tex]x = 2[/tex] are included in the open interval [tex](-2,\, 2)[/tex]. Additionally, [tex]a,\, b \in [-2,\, 2][/tex], meaning that [tex](a,\, b)[/tex] is a subset of the open interval [tex](-2,\, 2)[/tex]. Thus, neither zero would be in the subset [tex](a,\, b)[/tex]. In other words, there is no [tex]x \in (a,\, b)[/tex] such that [tex]f^{\prime}(x) = 0[/tex]. Contradiction.
Hence, [tex]f(x) = x^{3} - 12\, x + 11[/tex] has at most one root over the interval [tex][-2,\, 2][/tex].

How much force does the atmosphere exert on one side of a vertical wall 4. 00-m high and 10. 0-m long?
A force of 4.05×10⁶ N was exerted on one side of the wall.
What is the force?Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction.
The following data were obtained from the question:
Breadth (B) = 4 m
Length (L) = 10 m
Standard pressure (P) = 101325 Nm¯²
Next, we shall determine the area of the wall. This can be obtained as follow:
Area (A) = length (L) × breadth (B)
A = 10 × 4
A = 40 m²
Finally, we shall determine the force exerted on one side of the wall as follow:
Standard pressure (P) = 101325 Nm¯²
Area (A) = 40 m²
Pressure (P) = Force (F) /Area (A)
101325 = F/40
F = 101325 × 40
F = 4.05×10⁶ N.
Therefore, a force of 4.05×10⁶ N was exerted on one side of the wall.

The range of the graph is the set of output values, and the range is (d) (-infinity,infinity)
How to determine the range?From the graph in the complete question, we can see that the output values (i.e. the y values) extend indefinitely on both sides of the graph
This means that the range of the graph is the set of all real numbers.
This in other words means that (-infinity,infinity)
