Answer:

20 square meters

Step-by-step explanation:

To do this continue the line of the top of the rectangle so you split the figure into a triangle and a rectangle. The dimensions of the rectangle would be 8 by 2, so 8 * 2 = 16. Next, the dimensions of the triangle would be (4 - 2) by (8 - 4) = 2 by 4. The area would then be 2 * 4 = 8/2 = 4.

All you have to do now is add those two areas together, 16 + 4 = 20 square meters.

A scuba diver returning to the surface swims to move up quickly, then waits a few meters below the surface to avoid pressure iss

Juliette [100K]

Given:

The function f represents the diver's distance from sea level over time, in seconds.

$f(x)=\begin{cases}3x+1 & \text{ if } -9$

To find:

The correct statement for the domain.

Solution:

Domain is the set of input values for which the function is defined.

Here, x values are the input values and they represent time intervals on which the function is defined

Here, the possible intervals for x are $-9$ .

$Domain=(-9,-2]\cup (-2,1]\cup (1,7)$

$Domain=(-9,7)$

Therefore, the domain is the time interval (−9, 7). Hence the correct option is A.

For the given values of n and d, find integers q and r such that n = dq + r and 0 ≤ r < d. n = −67, d = 8

Firlakuza [10]

Answer:

$q = 8$

$r = 3$

Step-by-step explanation:

Given

$n = dq + r$

$0 \le r < d$

$n = 67$ --- not -67

$d = 8$

Required

Find q and r

Substitute values for d and b

$n = dq + r$

$67 = 8 * q + r$

$67 = 8q + r$

Make q the subject

$q = \frac{67 - r}{8}$

$0 \le r < d$ means that r is less than 8 but greater than or equal to 0

And r and q are integers.

Let $r = 3$

$q = \frac{67 - 3}{8}$

$q = \frac{64}{8}$

$q = 8$

No other true values of r and q can be gotten.

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. B = 107°, a

Archy [21]

Answer: $105.19 \text{ square cm}$

Step-by-step explanation:

Since, by the SAS formula of finding the area of triangle,

The area of triangle, $A = \frac{1}{2}\times s_1\times s_2\times sin\theta$

Where, $s_1$ and $s_2$ are adjacent sides and $\theta$ is the included angle of these sides

Here, $s_1=22$ $s_2=10$

And, $\theta=107^{\circ}$

Thus, the area of the triangle ABC,

$A = \frac{1}{2}\times 22\times 10\times sin (107)^{\circ}$

$A = 110\times 0.95630475596$

$A = 105.193523156\approx 105.19\text { square cm}$

Therefore, Third Option is correct.
