Answer:

74°

Step-by-step explanation:

Let ½(theta) = X

Tan(X) = opposite/adjacent

= 7.5/10

X = (tan^-1)(0.75)

X = 36.8698976458

Theta = 2X = 2(36.8698976458)

Theta = 73.7397952916

Nearest degree: 74°

Step-by-step explanation:

11) y = -1x - 2

12) y = -(3/2)x + 3

13) y = 3x - 2

14) y = (3/4)x + 1

15) y = (1/2)x + 1

16) y = -(2/5)x

17) y = 7x + 2

18) y = (4/3)x - 4

krok68 [10]

Answer:

$a = 73.84$ , $b = -23.64$ , $c = 83.97$ , $d = 21.73$

Step-by-step explanation:

1880:

The predicted value is:

$f(80) = 1.363\cdot (80) - 35.2$

$f(80) = 73.84$

The residual value is:

$\Delta f = 50.2 - 73.84$

$\Delta f = -23.64$

1920:

The predicted value is:

$f(120) = 7.8 \cdot 1.02^{120}$

$f(120) = 83.97$

The residual value is:

$\Delta f = 105.7 - 83.97$

$\Delta f = 21.73$

Mara thinks x< 6 will earn the highest score here.

Mamont248 [21]

This question was not correctly written

Correct Question

Mara thinks x ≤ 6 will earn the highest score here.

David thinks x < 6 will.

Who is correct?

Answer:

Mara is correct

Step-by-step explanation:

In the above question, we are given two inequality equations

1) Mara: x ≤ 6

2) David : x < 6

For David , x < 6 means the score which is represented by x is less than 6

For Mara, x ≤ 6 means the score which is represented by x is less than or equal to 6

Therefore, Mara is correct because x ≤ 6 will earn the highest score here.
