Step-by-step explanation:
1st term = an= - 5n + 8 = -5(1) + 8
= -5 + 8
a1 = 3
2nd term = an= - 5n + 8 = -5(2) + 8
= -10 + 8
= -2
3rd term = an= - 5n + 8 = -5(3) + 8
= -15 + 8
= -7
4th term = an= - 5n + 8 = -5(4) + 8
= -20 + 8
= -12
5th term = an= - 5n + 8 = -5(5) + 8
= -25 + 8
= -17

2 (x + 3 )= -x
Answer:
-2 =x
Step-by-step explanation:
2 (x + 3 )= -x
Distribute the 2
2x+6 = -x
Subtract 2x from each side
2x+6-2x = -x-2x
6 = -3x
Divide each side by -3
6/-3 = -3x/-3
-2 =x
Answer:
x = -2
Step-by-step explanation:
2 (x + 3) = -x
2x + 6 = -x
- 6 -6
2x = -x - 6
+x + x
3x = -6

The height H of an ball that is thrown straight upward from an initial position 3 feet off the ground with initial velocity of 90 ft./s is given by the equation H equals 3+90 T -16 T squared where t equals time in seconds. After how many seconds will the ball be 84 feet above the ground
Answer:
The ball will be 84 feet above the ground 1.125 seconds and 4.5 seconds after launch.
Step-by-step explanation:
Statement is incorrect. Correct form is presented below:
The height [tex]h(t)[/tex] of an ball that is thrown straight upward from an initial position 3 feet off the ground with initial velocity of 90 feet per second is given by equation [tex]h(t) = 3 +90\cdot t -16\cdot t^{2}[/tex], where [tex]t[/tex] is time in seconds. After how many seconds will the ball be 84 feet above the ground.
We equalize the kinematic formula to 84 feet and solve the resulting second-order polynomial by Quadratic Formula to determine the instants associated with such height:
[tex]3+90\cdot t -16\cdot t^{2} = 84[/tex]
[tex]16\cdot t^{2}-90\cdot t +81 = 0[/tex] (1)
By Quadratic Formula:
[tex]t_{1,2} = \frac{90\pm \sqrt{(-90)^{2}-4\cdot (16)\cdot (81)}}{2\cdot (16)}[/tex]
[tex]t_{1} = 4.5\,s[/tex], [tex]t_{2} = 1.125\,s[/tex]
The ball will be 84 feet above the ground 1.125 seconds and 4.5 seconds after launch.

What is the sum of the interior
angles of a polygon that has 19
sides?
[?] degrees
Please helpppp!!!!!
Answer:
[tex]\boxed {\boxed {\sf 3060 \textdegree}}[/tex]
Step-by-step explanation:
The sum of a polygon's interior angles is found using this formula:
[tex]180 \textdegree (n-2)[/tex]
where n is the number of sides. This polygon has 19 sides.
[tex]n=19[/tex]
[tex]180 \textdegree*(19-2)[/tex]
[tex]180 \textdegree*(17)[/tex]
[tex]3060 \textdegree[/tex]
The sum of the interior angles is 3,060 degrees.

The missing dimension of the prism is A
because the volume of the rectangular prism equals the product of the sides, we have:
V = (x - 1)(x - 3)A
but V = x³ - 8x² + 19x - 12
=> x³ - 8x² + 19x - 12 = (x - 1 )(x - 3)A
⇔ x²(x - 1) - 7x(x - 1) + 12(x - 1) = (x - 1)(x - 3)A
⇔ (x² - 7x + 12)(x - 1) = (x - 1)(x - 3)A
⇔ (x² - 3x - 4x + 12)(x - 1) = (x - 1)(x - 3)A
⇔ (x - 3)(x - 4)(x - 1) = (x - 1)(x - 3)A
⇒ A = x - 4

Find the values of A and B in each triangle: show your work
Answer:
soh cah toa
to find a use sin =opp/hyp
sin 32=opp or a /hyp
sin 32*hyp=9.53
then to find b you can pythagorean theorem or just use cah or cos =adj/hyp
same process as above only using cos instead of sin
you get 15.3
then a^2+b^2=c^2
9.53^2+15.3^2=18^2 just to check or to use to find either a or b given c and either a or b

Find the zeros of the function.
Enter the solutions from least to greatest.
g(x) = -10x2 + 490
lesser =
greater x =
Answer:
Lesser = -490
Greater x = 100x
Step-by-step explanation:
The zeros is basically the opposite numbers to make the equation equal to 0.
We have -10x^2(I believe it's a power)
and we have + 490
so,
-10x^2 = -100x
So the opposites to make those is:
+ 100x because, -100x + 100x = 0
and -490 because, 490 - 490 = 0.

Two sides of a triangle measure 20 cm and 30 cm. Which of the following could be measure of the third side.
A-3cm
B-6cm
C-11cm
Answer:
11 cm
Step-by-step explanation:
the other two choices are too short
If 30 is the hypotenuse, the other two sides must exceed 30.
Answer:
C-11cm
Step-by-step explanation:
The sum of two sides of a triangle must always be bigger than the third!
3+20 is less than 30
6+20 is less than 30
11+20 is greater than 30!

A 13 feet ladder is placed 5 feet away from a wall. The distance from the ground straight up to the top of the wall is 13 feet Will the ladder the top of the wall?
Answer:
the answer is
a^2 + b^2 = c^2
5^2 + b^2 = 13^1
25 + b^2 = 169
b^2 = 144
b = 12
or
The ladder is the hypotenuse, and the two legs are distance from the wall and height of the wall. If it is moved 5 feet away, it will reach 12 feet high, for 5^2+12^2=13^2.

Help please! Will give brainly
Answer:
C
Step-by-step explanation:
First we need to find W. You can do that by dividing 47.25 by 5.25.
47.25 / 5.25 = 9
So W = 9.
Now we do both equations to see which one is correct.
Equation A: 3/4 × 9 = 6 3/4, which is true.
Equation B: 9 - 10.24 = -1.24, which is also true.
Therefore, both equations give you the same solution, C.
