Answer:
3*x-4
Step-by-step explanation:
2x^2 + 3x = -5
Trying to find the solution,
Thank you.
Answer:
x = 1/2 or -2
Step-by-step explanation:
2x^2 +3x -2 = 0
(2x - 1) ( x + 2 ) = 0
(2x-1) = 0 ______ x = 1/2
or
(x +2 ) = 0 ______ x = -2
A cylinder has a base diameter of 18 feet and height of 15 feet . What is it’s volume in a cubic feet to the nearest tenths place ?
it's 3817.04 but you round to the nearest tenth
Can someone please help me with this problem?
Answer:
[tex]sin(\theta)=\frac{40}{41} \\cos(\theta)=\frac{9}{41} \\tan(\theta)=\frac{40}{9}\\csc(\theta)=\frac{41}{40} \\sec(\theta)=\frac{41}{9} \\cot(\theta)=\frac{9}{40}[/tex]
Step-by-step explanation:
Notice we can use the Pythagorean theorem to find the measure of the unknown side via:
[tex]123^2=120^2+x^2\\x^2=729\\x=\sqrt{729} \\x=27[/tex]
and now, knowing all the sides, we can find all te trigonometric functions of the angle [tex]\theta[/tex]:
[tex]sin(\theta)=\frac{opp}{hyp} = \frac{120}{123} =\frac{40}{41} \\cos(\theta)=\frac{adj}{hyp} = \frac{27}{123} =\frac{9}{41} \\tan(\theta)=\frac{opp}{adj} = \frac{120}{27} =\frac{40}{9}\\csc(\theta)=\frac{41}{40} \\sec(\theta)=\frac{41}{9} \\cot(\theta)=\frac{9}{40}[/tex]

Can someone help me find the GCF of 35 and 63 please show your work thank you
The first step to find the gcf of 35 and 63 is to list the factors of each number. The factors of 35 are 1, 5, 7 and 35. The factors of 63 are 1, 3, 7, 9, 21 and 63. So, the Greatest Common Factor for these numbers is 7 because it divides all them without a remainder.
To sum up, the gcf of 35 and 63 is 7. In common notation: gcf (35,63) = 7.

The slope of QR is *4 and the slope of ST is
3
If QR I ST, determine and state the value of x.
Answer:
E. -1/2
Step-by-step explanation:
When two lines are said to be perpendicular to each other, the slope of one is the negative reciprocal of the other.
Therefore, given that [tex] \frac{x - 1}{4} [/tex] is the slope of [tex] \overline{QR} [/tex], and ⁸/3 is the slope of [tex] \overline{ST} [/tex], if both lines are perpendicular, it means that the slope of [tex] \overline{ST} [/tex] would be the negative reciprocal of the slope of [tex] \overline{QR} [/tex].
Therefore:
[tex] \frac{x - 1}{4} = -\frac{3}{8} [/tex]
Cross multiply
[tex] (x - 1)(8) = (-3)(4) [/tex]
[tex] 8x - 8 = -12 [/tex]
Add 8 to both sides
[tex] 8x = -12 + 8 [/tex]
[tex] 8x = -4 [/tex]
Divide both sides by 8
[tex] x = \frac{-4}{8} [/tex]
[tex] x = \frac{-1}{2} [/tex]

Step-by-step explanation:
You are rolling one die. Let event A = rolling a six and let event B = rolling a number less than
four. What is the probability of A or B?
Answer:
2/3
Step-by-step explanation:
A = rolling a six
B = rolling a number less than 4
Probability of A or B
P(A) or P(B) = P(A) + P(B) - P(AnB)
Probability = (number of required outcome / Total possible outcomes)
P(A) = 1 / 6
P(B) :
Required outcomes = (3, 2, 1) = 3
P(B) = 3/6 = 1/2
P(AnB) = A={6} ; B = {1,2,3} ; AnB = {}
P(AnB) = 0
Hence,
P(A) or P(B) = 1/6 + 1/2 - 0
= (1 + 3) / 6
= 4/ 6
= 2/3

How many degrees is StartFraction 15 Over 16 EndFraction pi radians? 84.375° 93.75° 168.75° 337.5°
Answer:
x = 168.75°
Step-by-step explanation:
Angle Measurement Units
To convert from different units for angle measurements, we have to recall that:
180 degrees = π radians
If we are given the angle in degrees, multiply by π/180 to convert it to radians.
If the angle is given in radians, multiply by 180/π to convert to degrees.
We are given the angle:
[tex]\displaystyle x=\frac{15}{16}\pi[/tex]
Multiplying by 180/π:
[tex]\displaystyle x=\frac{15}{16}\pi\cdot \frac{180}{\pi}[/tex]
Simplifying:
[tex]\displaystyle x=\frac{15*180}{16}[/tex]
x = 168.75°
Answer:
C. 168.75 degrees
Step-by-step explanation:

Which of the following best describes the graph above?
A. Function only
B. Relation only
C. Both relation and function
D. Neither relation nor a function
Answer: C
Step-by-step explanation:
We know that a relation is any set of ordered pairs, but a function is when there is only one y value for x value.
So, basically, if a graph is a function, it is a relation as well.
Let’s check if this is a function.
We can use the vertical line test- if we draw a vertical line through any point on the graph and it only intersects one point, it is a function
In our case, it passes the vertical line test.
Therefore, it is both a function and a relation, which corresponds to letter C.
Hope this helps! :)
