Answer:
135
Step-by-step explanation:
Given:
[tex]x = 5[/tex]
To determine a numerical value for the expression, simply substitute the value of "x" into the expression and simplify the expression, if necessary, to determine a specific number for the expression provided.
[tex]\implies 5x^{2} + 2x[/tex][tex]\implies 5(5)^{2} + 2(5) \longrightarrow \longrightarrow \longrightarrow (x = 5)[/tex][tex]\implies 5(5)(5) + 2(5)[/tex][tex]\implies 125 + 10[/tex][tex]\implies 135[/tex]Therefore, the value of the expression [tex]5x^{2} + 2x[/tex] when x = 5 is 135.

Mr. Graham invested some of his $18,000 in bonds that made a 5% profit and the rest in bonds that made a 12% profit. If the profit on the 12% bonds was $885 more than the profit on the 5% bonds, how much did Mr. Graham
invest in the 5% bonds?
Answer:
$7500
Step-by-step explanation:
Let investment in 5% bond be x
(18000 - x) * 12% - x * 5% = 885
18000*12 - 12x - 5x = 88500
216000 - 88500 = 17x
x = 7500

Genevieve is in charge of creating a five-digit code to lock and unlock a secure cabinet. she can use any code from 0 through 9 and she could use each digit as many times as she wants she knows wants to start the code with a prime number. how many possible codes that start with the prime number could Genvieve create?
A.40,000
B.50,000
C.400,000
D.500,000
Answer:
40,000
Step-by-step explanation:
I took the test
There are 40,000 possible codes that start with the prime number could Genvieve create.
For the first digit, Genevieve wants to start with a prime number.
The prime numbers between 0 and 9 are 2, 3, 5, and 7.
So, there are 4 choices for the first digit.
For the remaining four digits, she can choose any number from 0 through 9, including the prime numbers.
Since there are 10 choices for each of the four remaining digits, the total number of possible codes for those digits is 10⁴.
To calculate the total number of possible codes that start with a prime number, we multiply the number of choices for the first digit (4) by the number of choices for the remaining four digits (10⁴):
4 × 10⁴ = 40,000
Therefore, the correct answer is A) 40,000.

What is the measure of the larger acute angle of the triangle? Round your answer to the nearest
tenth of a degree.
Answer:
50.8°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between side lengths and trig functions for a right triangle. Here, you are given the short side and the hypotenuse, and asked for the largest acute angle.
__
The short side is adjacent to the largest acute angle, so the relevant relation is ...
Cos = Adjacent/Hypotenuse
cos(β) = (2√6)/(2√15) = √0.4
The angle measure is found using the inverse cosine function:
β = arccos(√0.4) ≈ 50.8°
The larger acute angle is about 50.8°.
The sides lengths 4, 6, 9 can be used to form the sides of a triangle.
