Answer:

PLS MARK BRAINLIEST

Step-by-step explanation:

Sn = n/2(2a+(n-1)d)

a=6

a+ 4d= 18

6 +4d= 18

4d = 12

d = 3

162= n/2(12+(n -1)3)

324=n(12 + 3n-3)

324=12n + 3n^2 - 3n

3n^2 + 9n-324=0

3n^2+ 36n-27n -324 =0

3n(n+12) -27(n+12)= 0

3n-27 =0; n+ 12=0

n=9 ; n= -12

since n can't be negative n=9

The number of terms is 9

Answer:

x = 15

Step-by-step explanation:

3x + 14 = 59

subtract 14 from both sides

3x = 45

divide both sides by 3

x = 15

Answer:

15

Step-by-step explanation

Subtract 14 from both sides and the do 45 divided by 3 and it gives you your answer 15

Answer:

=4b^2−b+1

Step-by-step explanation:

4b2+−2b+7b+−6b+1

4b2+−2b+7b+−6b+1=(4b2)+(−2b+7b+−6b)+(1)

=4b^2−b+1

4b²−2b+7b−6b+1

first combine light terms.

[tex] {4b}^{2} - 2b + 7b - 6b + 1[/tex]

light terms equal:

[tex] - 2b + 7b - 6b[/tex]

let's solve:

[tex] {4b}^{2} - 2b + 7b - 6b + 1[/tex]

[tex] = { 4b}^{2} - b + 1[/tex]

Answer:

x = 6

∠PQR = 29

Step-by-step explanation:

Sum of interior angles in a triangle is 180,

15x - 4 + 4x + 5 + 65 = 180

15x + 4x + 5 - 4 + 65 = 180

19x + 1 + 65 = 180

19x + 66 = 180

19x = 180 - 66

19x = 114

x = 114 / 19

x = 6

∠PQR = 4x + 5

Substitute x = 6,

∠PQR = 4 ( 6 ) + 5

          = 24 + 5

∠PQR = 29

Answer: 1

Step-by-step explanation:

the equation of the graph will be y = f(x).

f(0) means the the value of y when x = 0, which is 1

or you can view it as where does the graph cuts the y-axis (x=0).

Answer:

using the formula x/a + y/b =1

a: slope intercept on the x axis

b:slope intersect on the y axis

x/0 + y/3 = 1 (since x/0 is undefined ,the slope doesn't exist and it is impossible for a slope to be linear)

Based on the temperature change and the amount of time it did so, the average change in temperature per hour is -3.5°F.

The average change in temperature per hour can be found by:

= Temperature change / Number of hours

Solving would give:

= -23.8 / 6.8

= -3.5°F

We can therefore conclude that in every hour of this cold day, the temperature changed by an average of -3.5°F.

The value of the function g(h(10)) will be 2√2.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Given that g(x) is √(x-4) and h(x) is 2x - 8. The value of the function g(h(10)) will be calculated as:-

h(x) = 2x - 8

At x = 10 the value of the function h(x) will be:-

h(10) = ( 2 x 10 ) - 8

h(10) = 20 - 8

h(10 ) = 12

Calculate the value of the function g(h(10)):-

g(h(10)) = √(x-4)

g(h(10)) = √(h(10)-4)

g(h(10)) = √( 12 -4 )

g(h(10)) = √( 8 )

g(h(10)) =  2√2.

Therefore, the value of the function g(h(10)) will be 2√2.
