The function N(X) = 90(0.86)* + 69 can be used to predict the temperature of a

dezoksy [38]

Answer: -8.93

Step-by-step explanation:

Given the function:

N(X) = 90(0.86)^x+ 69

X in the interval [0, 6]

For X = 0

N(0) = 90(0.86)^0 + 69

90 + 69 = 159

For X = 6

N(6) = 90(0.86)^6 + 69

90(0.404567235136) + 69

= 105.41105116224

Therefore, average change of change in temperature ;

(temp 2 - temp 1) / ( time 2 - time)

(105.41105116224 - 159) / (6 - 0)

= - 53.58894883776 / 6

= - 8.93149147296

= - 8.93

Can someone help me my grade are bad

Likurg_2 [28]

Answer:

8.31

Step-by-step explanation:

Using the Pythagorean Theorem:

$a^2+b^2=c^2$

$10^2+b^2=13^2$

$100+b^2=169$

$b^2=69$

$b = \sqrt{69}$

$b = 8.306623863$

The side length for $x$ , rounded to the nearest hundredths, would be 8.31.

A thread is wound 200 times round a reel of diameter 5 cm. Use the value 3 for it to find the approximate length of the thread i

Radda [10]

Answer:

Length of the thread = 30 metres

Step-by-step explanation:

Length of the thread in one round of a reel = Circumference of the reel

C = $2\pi r$

Since radius of the reel = $\frac{\text{Diameter}}{2}$

= $\frac{5}{2}$

= 2.5 cm

Circumference of the reel = 2(π)(2.5)

= 5π

= 5×3

= 15 cm

Length of the thread wound in one round around the reel = 15 cm

Since, thread is wound 200 times round a reel, length of the thread

= 200 × 15

= 3000 cm

≈ 30 metres

Therefore, Option (B) will be the answer.

Graph the line with a slope of -3/2 that passes through the point (-1,2)

olga nikolaevna [1]

Answer:

See diagram

Step-by-step explanation:

The line with the slope of $-\dfrac{3}{2}$ has the equation

$y=-\dfrac{3}{2}x+b$

This line passes through the point (-1,2), so

$2=-\dfrac{3}{2}\cdot (-1)+b\\ \\b=2-1.5\\ \\b=0.5$

The line has the equation

$y=-1.5x+0.5$

This line intersects the y-axis at point (0,0.5) and the y-axis at point (1/3, 0). Plot these points and connect them with the straight line (see attached diagram)
