Could someone please help and answer this? Ty :))

Mathematics
1 answer:
iris [78.8K]3 years ago

Answer:

Step-by-step explanation:

Angle JKL is similar to angle PQR. This means that the ratio of the length of each side of ∆JKL to the length of the corresponding side of ∆ PQR is constant. Therefore,

JK/PQ = KL/QR = JL/PR

Therefore,

x/28 = 38/42

Cross multiplying, it becomes

x × 42 = 28 × 38

42x = 1064

Dividing the left hand side and the right hand side of the equation by 42, it becomes

42x/42 = 1064/42

x = 25.33 rounded up to the nearest 2 decimal places.

Answer:

<h2>The table does not show a linear function</h2>

Step-by-step explanation:

\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{From the table we have:}\\\\(5,\ 24),\ (10,\ 21),\ (15,\ 17),\ (20,\ 13)\\\\\text{Check}\\\\\dfrac{21-24}{10-5}=\dfrac{-3}{5}=-\dfrac{3}{5}\\\\\dfrac{17-21}{15-10}=\dfrac{-4}{5}=-\dfrac{4}{5}\\\\-\dfrac{3}{5}\neq-\dfrac{4}{5}

Helpp please!! 10 points

Slope is 1.3

take your 2 points and make a triangle, then count the small boxes to the point in the middle where they met. ( REMEMBER THE X&Y RULES)
you should get 4/3, you need to divide and put it into decimal form.
GOOD LUCK! :))

skelet666 [1.2K]

\bf \textit{arc's length}\\\\ s=r\theta ~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad radians\\ \hrulefill\\ r=3\\ \theta =\frac{7\pi }{3} \end{cases}\implies s=3\cdot \cfrac{7\pi }{3}\implies s=7\pi
