the diagram shows a right angle triangle..

Answers

Area of triangle = base x height x 1/2

18 = (x - 1) • (x + 4) • 1/2

18 • 2 = (x - 1) • (x + 4)

36 = (x - 1)(x + 4)

36 = (x² + 4x - 1x - 4)

36 = x² + 3x - 4

0 = x² + 3x - 4 - 36

x² + 3x - 40 = 0

(x + 8)(x - 5) = 0

x + 8 = 0 or x - 5 = 0

1) James deposited $4,000 into an account. He made
no additional deposits or withdrawals. James earned
5.75% annual simple interest on the money in the
account.
What was the balance in dollars and cents in James
account at the end of 5 years?

Answers

Answer:

$5150

Step-by-step explanation:

Given data

Principal=$4000

Rate=5.75%

Time= 5 years

The expression for the balance on  simple interest is

A=P(1+rt)

substitute

A=4000(1+0.0575*5)

A=4000(1+0.2875)

A=4000X(1.2875)

A=$5150

Hence the  balance is $5150

Ruth wants to put a birdseed mix in her birdfeeder. The mix is 30% wild bird seed and 70% sunflower seed. Her birdfeeder can hold 8 cups of birdseed. How many cups of the mix will be wild bird seed?

Answers

Answer:

2.4 of the cups

Step-by-step explanation:

30% of 8 = 2.4

70% of 8 = 5.6

30% + 70% = 100%

2.4 + 5.6 = 8

{45x+6y=15-x+18y=11 is..........................

Answers

Answer:

Step-by-step explanation:

45x+6y=15

-x+18y = 11

let's use elimination, the other way is by substitution,  either way works but, it looks to me like elimination would be easy with the  'y'

3(45x+6y=15)

135x + 18y = 45 ( subtract  2nd eq.  from 1st )

-( -x+18y = 11 )

136x +0y =34

x = 34 /136

x = 1 /4

there is X

plug that back into either of the 1st or 2nd equations to solve for y

- 1/4 + 18 y = 11

18y = 11 1/4

18y = 45/4

y = 45/4 *  1/18

y = 45/ 72

8. In AABC, mC = 90° and sin A =
What is m angle B in degrees?
A. 30°
B. 45°
C. 60°
D. There is not enough information to determine.

Answers

Answer:

C

Step-by-step explanation:

The degrees of a triangle add up to 180.

Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.

Angle A is equal to sinA=1/2.

sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.

90-30=60.

That leaves you with 60 degrees for angle B.

8) 19

9) 9

Answer:

1) = -4

2) = 5

4) = 8

5) = 7

6) = -64

7) = -10

8) = 19

9) = 9

10) = -56

Step-by-step explanation:

1) (-4 + 2)^2 = -2^2 = -4

2) 25 / (9 - 4) = 25 / 5 = 5

3) 4 * 5 - 3 = 20 - 3 = 17

4) 2(2 + 2) = 2 * 4 = 8

5) (-10 + 5) / 5 + 8 = -5 / 5 + 8 = -1 + 8 = 7

6) (-3 - 1)^3 = -4^3 = -64

7) 5(5 - 7) = 5 * -2 = -10

8) 2 * 7 + 5 = 14 + 5 = 19

9) (5 * 3 + 3) / 2 = (15 + 3) / 2 = 18 / 2 = 9

10) 8(-1 - 6) = 8 * -7 = -56

Dilate Point B by a scale factor of 1/2

Answers

Answer:

( -1.5 , 1 )

Step-by-step explanation:

Hello There!

When dilating a point we divide or multiply the coordinates by whatever the scale factor is

Because the scale factor is 1/2 we just have to divide the coordinates of point B by 2

Preimage coordinates - ( -3 , 2 )

-3/2=-1.5 or -3/5

2/2=1

Dilated image coordinates ( -1.5 , 1 )

A sine curve with a period of 8, an amplitude of 2, a left phase shift of /3, and a vertical translation down 5 units.

Answers

Answer:

[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]

Step-by-step explanation:

The standard form for a sinusoidal function is given by:

y = Asin[B(x - C)] + D

Where A is the amplitude of the sine wave, the period is 2π/B, C is the phase shift and D is the vertical displacement / translation

Given:

A = 2, D = -5 (down), C = -3 (left).

8 = 2π/B; B = π/4

Therefore:

[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]
