Question 7: Option 1: x = 33.5°

Question 8: Option 3: x = 14.0°

Step-by-step explanation:

Question 7:

In the given figure, the value of perpendicular and hypotenuse is given, so we have to use any trigonometric ratio to find the value of angle as the given triangle is a right-angled triangle

So,

Perpendicular = P = 32

Hypotenuse = H = 58

So,

$sin\ x = \frac{P}{H}\\sin\ x = \frac{32}{58}\\sin\ x = 0.5517\\x = sin^{-1} ( 0.5517)\\x =33.48$

Rounding off to nearest tenth

x = 33.5°

Question 8:

In the given figure, the value of Base and Perpendicular is given, we will use tangent trigonometric ratio to find the value of x

So,

Perpendicular = P = 5

Base = B = 20

So,

$tan\ x = \frac{P}{B}\\tan\ x = \frac{5}{20}\\tan\ x = 0.25\\x = tan^{-1} (0.25)\\x = 14.036$

Rounding off to nearest tenth

x = 14.0°

Find the area enclosed by the x-axis and the curve x = 4 + et, y = t âˆ’ t2.

Dominik [7]

Find where the curve intersects the x-axis; this happens when y = 0:

y = t - t ² = 0 → t (1 - t ) = 0 → t = 0, t = 1

Then the area of the bounded region is

$\displaystyle\int_0^1 y(t) x'(t)\,\mathrm dt=\int_0^1 (t-t^2)e^t\,\mathrm dt=\boxed{3-e}$

(you can compute the integral by parts)

All real numbers less than or equal to 9 and greater than or equal to 7 please hurry

VashaNatasha [74]

Answer:

$7 \leq x \leq 9$

Step-by-step explanation:

Let $x$ represent the real numbers.

For the first part, all real numbers less than or equal to 9 in algebra is $x \leq 9$ .

For the second part, all real numbers greater than or equal to 7 in algebra is $x \geq 7$ .

To combine both inequalities, it would become $7 \leq x \leq 9$ .

Hope this helped! If not, please let me know! <3
