(7a^2 + 2a - 3)(4a^2 - 1) = 28a^4 +ma^3 - 19a^2 - 2a + 3
4a^2(7a^2 + 2a - 3) - 1(7a^2 + 2a - 3) = 28a^4 +ma^3 - 19a^2 - 2a + 3
28a^4 + 8a^3 - 12a^2 - 7a^2 - 2a + 3 = 28a^4 +ma^3 - 19a^2 - 2a + 3
28a^4 + 8a^3 - 19a^2 - 2a + 3 = 28a^4 +ma^3 - 19a^2 - 2a + 3

Cancel all the same terms

8a^3 = ma^3
Therefore, m = 8

Find measure angle GJK (5x + 8) (7x - 16)

Answers

Hi there!

[tex]\large\boxed{22^o}[/tex]

Find m∠GJK by finding the value of its complementary angle and subtracting from 90°.

Using the Alternate Interior Angle theorem:

m∠HJI = m∠JHG, so:

7x - 16 = 5x + 8

Solve for x:

2x - 16 = 8

2x = 24

x = 12

Substitute in this value of x to solve for m∠HJI:

7(12) - 16 = 84 - 16 = 68°

Thus:

m∠GJH = 90 - 68° = 22°

Keisha's softball team won 60% of 135 games, how much games did the team lose?

Answers

Answer:

54

Step-by-step explanation:

135(.6) = 81

total = 135

won = 81

lost = 54

OR you could just multiply 135 by 110%-60%, which is 40% or 0.4

135(.4) = 54



3. At a manufacturing plant, it is known that 8% of the computer chips produced are defective. A random sample of 20 chips is taken.

What is the probability that 3 of those chips are defective?

.

Answers

Answer:

Probability of three chip being defective is 0.012

Step-by-step explanation:

Probability of a computer chip being defective is 0.08 or 8%

Total random sample = 20

Probability of three chip being defective = 3/20 * 0.08

= 0.012

Answer:

B) 0.14

Step-by-step explanation:

N=20

K=3

P=0.08

CoE= 1140

1140 x (0.08)^3 x (.92)^17

1140 x (0.000512) x (0.2423) = 0.141425 or B

Jack manages a café. Each day he buys watermelons and mangoes in the (respective) ratio of 3:2. If on one day he buys 200 mangoes how many water melons would he have bought?

Answers

Answer:

300 watermelons

Step-by-step explanation:

3:2 ratio

3 is water melons and 2 is mangoes.

200 mangoes were purchased.

200/2=100

The unit rate is 100, so multiply 3 by 100, which is 300.

So Jack bought 300 watermelons, and 298 of which will be devoured by yours truly.

What type of conic section is represented by the parametric equations below? X=3cos(t)-1 y=3sin(t)+4

Answers

Answer:

Circle

Step-by-step explanation:

Examples of conic sections are the circle, the ellipse, the parabola and the hyperbola. Parametric equations are used to express the x and y variables in terms of a less complicated manner using a third variable (t or θ).

The parametric equation for a circle with an equation [tex](x-h)^2+(y-k)^2=r^2[/tex] is given by:

[tex]x=rcos(t)+h, y=rsin(t)+k[/tex]

where r is the radius of the circle and (h, k) is the center of the circle.

A conic section with a parametric equations X=3cos(t)-1, y=3sin(t)+4 is a circle with center at (-1, 4) and radius of 3. The equation of the circle is:

(x + 1)² + (y - 4)² = 3²

If x is an even number , the function f(x) = 2x-1 gives an odd number. Identify the set of odd numbers corresponding to this set of even numbers: {0,2,4,6,8}

Answers

Answer:

{-1, 3, 7, 11, 15}

Step-by-step explanation:

f(x) = 2x − 1, {0, 2, 4, 6, 8}

f(0) = 2*0 − 1 = 0 - 1 = -1

f(2) = 2*2 − 1 = 4 - 1 = 3

f(4) = 2*4 − 1 = 8 - 1 = 7

f(6) = 2*6 − 1= 12 - 1 = 11

f(8) = 2*8 − 1= 16 - 1 = 15

What is the value of x?

Answers

Answer:

x=7+1/2

Step-by-step explanation:

 We move all terms to the left:

3(x+4.5)-(36.)=0

We add all the numbers together, and all the variables

3(x+4.5)-36=0

We multiply parentheses

3x+13.5-36=0

We add all the numbers together, and all the variables

3x-22.5=0

We move all terms containing x to the left, all other terms to the right

3x=22.5

x=22.5/3

x=7+1/2

Elijah puts $550 in an account earning 8% simple interest annually. What is the total amount of money he will have in his account after 6 years, if no withdrawals or deposits are made?​

Answers

Answer:

814?

Step-by-step explanation:

Simple interest is I = PRT, so you can multiply the 550, by 1.08 by 6 to get the total.

The principal is 550, the rate is 0.08 (using 1.08 because the prior gives interest, and using a whole 1 with it will be the total), and the time is 6 years because the interest is simple annual.

use 0.08 instead of 1.08 when solving for interest.

Austin’s monthly gross pay is $4,200. Federal withholding is 16.05% of his pay. His other deductions total $321.30. What is his net pay.

Answers

Answer:

$3,204.6

Step-by-step explanation:

$ 4,200              represents       100% of his salary

x amount  of $   represents      16.05 % in federal withholding

after you line up $ with $ and % with % think cross multiplication

x = 4,200* 16.05/ 100 = $674.1 is the amount in federal withholding

Net pay = 4,200 -674.1 -321.30 =  $3,204.6
