With the help of proportions in the given similar triangles we know that the value of x is 3.5 units.
What is triangle similarity?Euclidean geometry states that two objects are comparable if they have the same shape or the same shape as each other's mirror image.
One can be created from the other more precisely by evenly scaling, possibly with the inclusion of further translation, rotation, and reflection.
These three theorems—Angle-Angle (AA), Side-Angle-Side (SAS), and Side-Side-Side (SSS)—are reliable techniques for figuring out how similar triangles are to one another.
So, in the given situation:
TR and WY are as follows:
TR/WU
24/2
2/1
Similarly,
TS/WV
2/1
7/x
7/3.5
Therefore, with the help of proportions in the given similar triangles we know that the value of x is 3.5 units.

A) x) = 7x-4
B)(x) = 2x - 14
C)(x) = 7x-9
D) (x)=2x-4
Answers
According to the given data the equation of the new function is (D) f(x) = 2x - 4.
What is meant by equation?An equation is a mathematical statement that indicates that two expressions are equal. It contains an equals sign "=" and may involve variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, exponentiation, etc.
According to the given information:If we translate the function h(x) = 2x - 9 up by 5 units, the new function f(x) will have the form:
f(x) = h(x) + 5
Substituting the definition of h(x) into this equation, we get:
f(x) = 2x - 9 + 5
Simplifying, we have:
f(x) = 2x - 4
Therefore, the equation of the new function is (D) f(x) = 2x - 4.

How to simplify the exponential expression?The exponential expression for this problem is defined as follows:

b) What is the balance after 1 year? 2 years? 5 years? 10 years?
c) What is the doubling time?
helppppppp
Answers
Answer: a) The exponential function that describes the amount in the account after time t, in years, is given by:
A(t) = Pe^(rt)
where P is the initial amount invested, r is the annual interest rate (as a decimal), and e is the mathematical constant approximately equal to 2.71828.
Substituting the given values, we get:
A(t) = 19665e^(0.068t)
b) To find the balance after 1 year, we substitute t = 1 in the above formula:
A(1) = 19665e^(0.068*1) = $20,983.88
To find the balance after 2 years, we substitute t = 2:
A(2) = 19665e^(0.068*2) = $22,429.45
To find the balance after 5 years, we substitute t = 5:
A(5) = 19665e^(0.068*5) = $29,137.27
To find the balance after 10 years, we substitute t = 10:
A(10) = 19665e^(0.068*10) = $43,127.22
c) The doubling time can be found using the formula:
t = ln(2)/r
where ln is the natural logarithm function. Substituting the given values, we get:
t = ln(2)/0.068 ≈ 10.20 years
Therefore, the doubling time is approximately 10.20 years.

First, multiply the coefficients: 6.2 x 3.5 = 21.7.

Raul received a score of 80 on a history test for which the class mean was 70 with standard deviation 10. He received a score of 75 on a biology test for which the class mean was 70 with standard deviation 2.5. On which test did he do better relative to the rest of the class?
Answers
Answer:
Raul performed better in the biology test
Step-by-step explanation:
Given
History
\(Score = 80\)
\(Mean = 70\)
\(Standard\ Deviation = 10\)
Biology
\(Score = 75\)
\(Mean = 70\)
\(Standard\ Deviation = 2.5\)
Required
Where did he perform better relative to other students
To do this, we simply calculate the z score in both tests and make comparison.
z score is calculated as thus;
\(z = \frac{x - Mean}{SD}\)
For history;
\(z = \frac{80 - 70}{10}\)
\(z = \frac{10}{10}\)
\(z = 1\)
For biology;
\(z = \frac{75 - 70}{2.5}\)
\(z = \frac{5}{2.5}\)
\(z = 2\)
Since the z score in the biology test is greater than that of the history test, then he performed better in the biology test

1520−{64÷−4}−[37( √ 121+345)(43−|−583|)+405]−{1745÷5−64 }
Answers
Answer:
36,425,886
Step-by-step explanation:
To rewrite the expression mathematically and simplify it, let's break it down step by step:
1520 − {64 ÷ -4} − [37(√121 + 345)(43 − |-583|) + 405] − {1745 ÷ 5 - 64}
Step 1: Evaluate the expressions within the absolute value symbols:
|-583| = 583
Step 2: Evaluate the square root:
√121 = 11
Step 3: Simplify the expression within the brackets:
37(11 + 345)(43 - 583) = 37(356)(-540)
Step 4: Evaluate the divisions:
64 ÷ -4 = -16
1745 ÷ 5 = 349
Now, we can rewrite the expression:
1520 - (-16) - [37(356)(-540) + 405] - (349 - 64)
Step 5: Simplify the multiplications:
37(356)(-540) = -36,425,040
Step 6: Simplify the additions and subtractions:
1520 - (-16) - [-36,425,040 + 405] - (349 - 64)
1520 + 16 - [-36,424,635] - 285
Step 7: Simplify further:
1536 + 36,424,635 - 285
36,426,171 - 285
36,425,886
Therefore, the simplified form of the expression is 36,425,886.

The statement ~(p v (p ^ q)) is classified as follows:

What are tautologies and contradictions?When a logic statement is always true, no matter the inputs, it is called a tautology. Otherwise, when a statement is always false, no matter the inputs, it is called a contradiction.
If the statement can be either true or false, depending on the boolean values of the inputs, the statement is called contingent.
The statement given in this problem is as follows:
~(p v (p ^ q))
From the precedence of operations, it is found that:
p ^ q can be either true or false, true if p = q = 1, false otherwise.p v (p ^ q) is false if p = q = 0 and true otherwise. ~(p v (p ^ q)) is the negation of the above statement, that is, true if p = q = 0 and true otherwise.Since the statement can be either true or false, depending on the boolean values of p and q, it is classified as contingent, and option c is correct.
