What are the x intercepts of the graph of this function? Y=6*2+10x - 4

Answers

Answer 1

Answer: x intercpe is when y=0

0=6x^2+10x-4
factor
0=2(3x^2+5x-2)
assume
0=3x^2+5x-2
0=(x+2)(3x-1)
set to zero
x+2=0
x=-2
3x-1=0
x=1/3

x intercepts are -2 and 1/3

D is answere

Answer 2

Answer: y = 6x^2 + 10x - 4
= 6x^2 + 12x - 2x - 4
= 6x(x + 2) - 2(x + 2)
= (6x - 2)(x + 2)

X intercepts are: -2 and 1/3

it is D

Please help.Whats thr volume of a right pyramid whose base is a square with a side 6m long and whose altitude is equal to the base side?

Answers

Answer: $72\text{ cubic meters}$

Step-by-step explanation:

Given: The base of the right pyramid is square with side = 6 m

Since, the altitude (h) is equals to the base , thus h=6m.

We know that the volume of the square pyramid is given by :_

$\text{Volume}=(1)/(3)a^2h$ , where a is the side of the square.

Then, the volume of the given right pyramid is given by :_

$\text{Volume}=(1)/(3)(6)^2(6)\n\n\Rightarrow\ \text{Volume}=72\text{ cubic meters}$

V=(1/3)(area of the base)(altitude)

V=(1/3)(6²)(6)= 72 m³

Roy is planning a trip to Iceland. His plane ticket will cost kr 60,170 (60,170 Icelandic krónur), his lodging will cost kr 47,249, he needs kr 39,877 for food, and his Icelandic friend has suggested that he bring at least kr 41,054 for sightseeing and spending money. However, Roy has only kr 160,500 saved up. How much more will he need before he can go on his trip?a. kr 23,350
b. kr 26,673
c. kr 27,850
d. kr 28,741

Answers

Answer: c. kr 27,850

Step-by-step explanation:

Given: The cost of plane ticket = kr 60,170

The cost of lodging = kr 47,249

The cost of food = kr 39,877

The amount suggested by friend for sightseeing and spending money = kr 41,054

Total cost for trip = $60,170+47,249+39,877+41,054$

$=kr\ 188,350$

Saved money by Roy = kr 160,500

The amount needed before he can go on his trip= $188,350- 160,500$

$=kr\ 27,850$

Hence, he need kr 27,850 before he can go on his trip.

Find the value of g(5) if g(x)=x3−x.

Answers

Answer:

g(5) = 120

Step-by-step explanation:

to evaluate g(5) , substitute x = 5 into g(x)

g(x) = x³ - x , then

g(5) = 5³ - 5 = 125 - 5 = 120

Select the correct answer. The sum of two numbers is -18. If the first number is 10, which equation represents this situation, and what is the second number? A. The equation that represents this situation is 10 − x = -18. The second number is 28. B. The equation that represents this situation is 10 + x = -18. The second number is -28. C. The equation that represents this situation is x − 10 = -18. The second number is -8. D. The equation that represents this situation is -10 + x = -18. The second number is -8.

Answers

Answer:-28

Step-by-step explanation:

Let A is the second number

the first number is 10.

The total is -18

=> 10 + A =-18 <=> A=-18-10=-28
