can yall tell me what im doing wrong? for 50 points.

Answer:

The radius is 8.

Step-by-step explanation:

Because OA is a radius and AB is a tangent, Angle A is a right angle. So you can use Pythagorean theorem (shortcut Pythagorean triple)

OA^2 + 15^2 = 17^2

OA^2 + 225 = 289

OA^2 = 64

OA = 8

OA is a radius, the radius = 8

-16[tex]t^{2}[/tex] +50t + 3

they ask what is the height after exactly 3 seconds,  so plug in the 3 for t

t(3) = -16*[tex]3^{2}[/tex] + 50*3 +3

t(3) =  -144 +150 +3

t(3) = 9 feet,  ( the ball has gone up and come back down most of the way )

Answer:

5.2 , 4.8 , 5.5 is 0.2

4.7 , 5,3 , 4.9 is 0.7

Answer:

Step-by-step explanation:

Front and back

Givens

base = 6 feet

height = 2

Formula

Area = 1/2 B * h

Area = 1/2 * 6 * 2

Area = (2) 1/2 * 12

Area = 12 square feet for both front and back

Base

The base is a rectangle. A rectangle has the formula of  Area =  L*w

Givens

L = 10 feet

W = 6 feet

Area = 10 * 6 = 60

Left roof

The left roof is also a rectangle. Area = L*w

Givens

L = 10 feet

W = 3 feet

Area = 3 * 10 = 30 feet^2

Right Roof

The right roof is a rectangle. Area = L*w

Givens

L = 10 feet

w = 4 feet

Area = 4 * 10 = 40 ft^2

Total area

Total Area = right roof + left roof + Base + front and back

Total Area = 40 + 30 + 60 + 12

Total Area = 142 feet ^2

Answer: Axel's statement would be incorrect. (If this is for Edgenulty, the answer is C)

Step-by-step explanation: No, because the relation does not pass the vertical line test for every possible input.

The Kendrick made a mistake in step 4 he did not multiply the term (7 - 2x) with -1, and he wrote 3x-7-2x=23 instead of 3x -7 +2x = 23

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Kendrick was given the equations:

Step 1: 4x+2y=14 ...(1)

3x-y=23 ...(2)

From the equation first:

Step 2:  2y = 14 - 4x

Step 3: y = 7 - 2x  put this value in the second equation

Step 4:  3x - (7 - 2x) = 23

Step 5: 3x -7 +2x = 23

Kendrick did a mistake in step 4 he did not multiply the term (7 - 2x) with -1

Thus, the Kendrick made a mistake in step 4 he did not multiply the term (7 - 2x) with -1, and he wrote 3x-7-2x=23 instead of 3x -7 +2x = 23

Answer:

B

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ FES is an exterior angle of the triangle , then

57° + ∠ F = 142° ( subtract 57° from both sides )

∠ F = 85°

Answer: Option B: 85°

Step-by-step explanation:

Finding E: 142 + 180 + E = 360

360 - 142 - 180 = 32

E = 32

Finding F: 57 + 32 + F = 180

180 - 57 - 32 = 85

F = 85

The magnitude of the force per unit length between the wires is [tex]3 \times 10^{-5} N/m[/tex].

In a wire carrying a current I 2, the force that each wire feels due to the presence of the other depends on the distance between them and the magnitude of the currents.

Force per unit length = magnetic permeability * (current 1) * (current 2) / (2 π distance between the wires).

The below expression for the force per unit length.

Moreover, before using the below formula we have to change the unit centimeter into a meter. So, we just divide the centimeter by 100.

[tex]\rm \dfrac{Force}{length}=\dfrac{u_0 \times i _1 \times i_2}{2\pi d}\\\\\dfrac{Force}{length}=\dfrac{u_0 \times i _1 \times i_2}{2\pi d}\\\\Where; \ \mu_0 = 4\pi \times 10^{-7} , i_13 . \ i_2 = 3 \ d=0.06[/tex]

Substitute all the values in the formula

[tex]\rm\dfrac{Force}{length}=\dfrac{u_0 \times i _1 \times i_2}{2\pi d}\\\\Where; \ \mu_0 = 4\pi \times 10^{-7} , i_13 . \ i_2 = 3 \ d=0.06\\\\ \dfrac{Force}{length}=\dfrac{4\pi \times 10^{-7} \times 3 \times3}{2\pi \times 0.06}\\\\ \dfrac{Force}{length}= 3 \times 10^{-5} N/m[/tex]

Hence, the magnitude of the force per unit length between the wires is [tex]3 \times 10^{-5} N/m[/tex].

Answer:

2 hours and 5 minutes.

Step-by-step explanation:

2 hours is 60mins+60mins which is equal to 120mins and then the extra 5mins

Hilary studied for a total of 2 hours and 5 minutes this week.

If Hilary studied for 25 minutes each day for five days this week, we can calculate the total study time by multiplying the number of minutes studied per day (25) by the number of days (5):

25 minutes/day × 5 days = 125 minutes

To convert this to hours and minutes, we need to divide the total minutes by 60 (since there are 60 minutes in an hour) to get the number of hours and find the remainder as minutes.

125 minutes ÷ 60 = 2 hours and 5 minutes

Therefore, Hilary studied for a total of 2 hours and 5 minutes this week.

Step-by-step explanation:

Answer:

(a) = 37π/180 radians

(b) = 37°

Step-by-step explanation:

Converting km/h ⇒ m/s :

⇒ 54 km/h x 5/18

⇒ 3 x 5

⇒ 15 m/s

===============================================================

Formula to calculate the angle :

⇒ tanθ = v/r

⇒ tanθ = (15 m/s)/(20 m)

⇒ θ = tan⁻¹ (0.75)

⇒ θ = 37°

=============================================================

Converting to radians :

⇒ Radian measure = Angle measure × π/180°

⇒ Radian measure = 37° × π/180°

⇒ Radian measure = 37π/180 radians
