Answer:

y=1.3 x - 0.21

Step-by-step explanation:

$y = (slope) \times x + (constant)$

set (-2.3,-3.2) in above

$- 3.2 = 1.3 \times ( - 2.3) + c$

then c=-0.21

Answer:

$A=77.04\ in^2$

Step-by-step explanation:

we know that

The area of the shaded sections is equal to the area of the circle minus the area of the triangle

$A=\pi r^{2} -\frac{1}{2}(b)(h)$

where

$r=12/2=6\ in$ ----> the radius is half the diameter

$b=12\ in\\h=6\ in$

substitute

$A=(3.14)6^{2} -\frac{1}{2}(12)(6)$

$A=77.04\ in^2$

The number of cars sold weekly by a new automobile dealership grows according to a linear growth model. The first week the deale

Sladkaya [172]

Answer:

Recursive Formula, Pₙ=Pₙ₋₁+2

Explicit Formula, Uₙ=4+2n

12 cars

Step-by-step explanation:

In Week 1, the dealer sold six cars, P₀=6

In Week 2, the dealer sold 8 cars, P₁=8

The difference in car sales between the first and second week is 2.

Therefore, for the (n+1)th week, the Recursive Formula is Pₙ=Pₙ₋₁+2

This is an arithmetic progression where the:

First term, a=6

Common difference, d =2

The nth term of an A.P. is given by Uₙ=a+(n-1)d.

The Explicit Formula, Uₙ=6+2(n-1)

=6+2n-2=4+2n

In the fourth week, U₄=4+2(4)=4+8=12

12 cars will be sold in the fourth week

Name the geometric term(s) modeled by each object

anyanavicka [17]

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The geometric term(s) modeled by each object are Hexagon, point, line, line, and plane, respectively.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. A line segment is also a line but the line with finite length and having fixed endpoints.

The geometric term(s) modeled by each object

9. Stop sign ⇒ Hexagon

10. Tip of pin ⇒ Point

11. Strings of a violin ⇒ Line

12. A car antenna ⇒ Line

13. A library card ⇒ Plane

Hence, The geometric term(s) modeled by each object are Hexagon, point, line, line, and plane, respectively.

Please help I am on number 1 please explain

jeka57 [31]

A % is out of a hundred, so you don't need the %/100. Then, you wouldn't do cross multiplication, you would just divide 15/27. Remember, it would be 15/27 because it's percent markup, not the percent the price increased by. So, doing that simple calculation on a calculator you get 0.5555. This converted to a percent is just moving the decimal to the right twice, or multiplied by a 100. That would give you 55.55%, and that's your answer. Make sense?

Find the height of the lamppost to the nearest inch.

diamong [38]

<h3>The height of lamp post to nearest inch is 110 inches</h3>

<em><u>Solution:</u></em>

We have to find the height of lamppost

From the figure in question,

Given is a right angled triangle

Where,

base = 40 inches

height = ?

By definition of tan,

$tan\ 70 = \frac{opposite}{base}\\\\tan\ 70 = \frac{height}{40}\\\\height = tan\ 70 \times 40\\\\height = 2.7474 \times 40\\\\height = 109.89 \approx 110$

Thus height of lamp post to nearest inch is 110 inches
