Since, angle between AB and CD is 90°,
AB⊥CD
True
Option 2
Since, angles between AB and EF is 90°, both will be perpendicular.
AB ⊥ EF

log Subscript 3 (2x-7)= 4
Answers
Answer:
x = 44
Step-by-step explanation:
You can rewrite logarithm equations like so:
[tex]log_{b}(x) = y\\\\x = b^y[/tex]
A way to remember this is the base in the logarithm is also the base in the exponent - then remember this base b is to the power of what's on the other side - and all this is equal to whatever's in the parentheses.
In this case,
[tex]log_3(2x-7) = 4\\2x - 7 = 3^4\\x = (3^4 + 7)/2 = 44[/tex]
If you start with 7,152 grams of a radioactive kind of lanthanum and the half-life is 93 minutes, how much will be left after 186 minutes
Answers
Answer:
1788 grams
Step-by-step explanation:
If you start with 7,152 grams of a radioactive kind of lanthanum and the half-life is 93 minutes, how much will be left after 186 minutes
We are to find Nt
The formula is given as:
Nt = No(1/2)^t/t½
Where
No = Initial amount = 7,152 grams
t = time elapsed = 186 minutes
t½ = Half life = 93 minutes
Nt = Amount of substance left
Nt = 7152(1/2)^186/93
= 1788 grams

A grocery store sells a bag of 6 oranges for $3.84. What is the cost of oranges, in
dollars per orange?
Answers
Answer:
Each orange would cost $0.64.
Step-by-step explanation:
If you do 3.84 and divide that by 6, you would get the answer of $0.64 for each orange.
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The cost of one orange is $0.64
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
6 oranges = $3.84
Divide both sides by 6.
1 orange = $3.84/6
1 orange = $0.64
Thus,
The cost of one orange is $0.64.

Answers
Answer: 1770 rupees
Step-by-step explanation:
To solve this, we first calculate the simple interest which will be:
= (P × R × T) / 100
= (1500 × 9% × 2) / 100
= (1500 × 0.09 × 2) / 100

The expression represents the distance in feet an object falls after seconds. The object is dropped from a height of 906 feet.
What is the height in feet of the object 2 seconds after it is dropped?
Write an expression representing the height of the object in feet seconds after it is dropped.
Answers
Answer:
[tex]842\ \text{ft}[/tex]
[tex]y(t)=906-16t^2[/tex]
Step-by-step explanation:
Let [tex]y[/tex] be the height the object from the ground.
[tex]s[/tex] be the initial height of the object = 906 ft
[tex]u[/tex] = Initial velocity = 0
[tex]g[/tex] = Acceleration due to gravity = [tex]32\ \text{ft/s}^2[/tex]
[tex]t[/tex] = Time
The expression would be
[tex]y(t)=s-ut-\dfrac{1}{2}gt^2\\\Rightarrow y(t)=906-16t^2[/tex]
The required expression is [tex]y(t)=906-16t^2[/tex]
At [tex]t=2\ \text{s}[/tex]
[tex]y(2)=906-16\times 2^2\\\Rightarrow y(2)=842\ \text{ft}[/tex]
The height of the object after 2 seconds of falling is [tex]842\ \text{ft}[/tex].

A. The area of the new circle is 7 times the area of the original circle.
B. The area of the new circle is 14 times the area of the original circle.
C. The area of the new circle is 49 times the area of the original circle.
D. The area of the new circle is squared root 7 times the area of the original circle.
Answers
Answer:
A
Step-by-step explanation:
The scale factor can be defined as the ratio of new dimension of an object after scaling to the original dimension. The are of the new circle is 49 times the area of the original circle. The correct answer is option C.
What is Scaling factor ?Scaling factor is a conversion factor used to change the size of a figure without changing its shape. When the size of a figure is increased, it called scaled up and when it decreases it is called as scaled down.
Given that, Scale factor of circle = 7.
Since, the scale factor of a circle is the ratio of new radius to original radius.
The new radius of circle can be written as,
r' = 7r
Thus, the area of new circle is π × (r')^2= π × (49r^2).
Hence, the area of new circle is 49 times the original circle.
