Answer:

answer will be an=3n+11

Step-by-step explanation:

because when we substitute them...it make sense.

<em>the</em><em> </em><em>rule</em><em> </em><em>is</em><em> </em><em>an</em><em>=</em><em>3</em><em>n</em><em>+</em><em>1</em><em>1</em>

<em>lets</em><em> </em><em>substitute</em><em>:</em>

<em>(</em><em>i</em><em>)</em><em>.</em><em>1</em><em>4</em><em>=</em><em>3</em><em>(</em><em>1</em><em>)</em><em>+</em><em>1</em><em>1</em>

<em>(</em><em>ii</em><em>)</em><em>1</em><em>7</em><em>=</em><em>3</em><em>(</em><em>2</em><em>)</em><em>+</em><em>1</em><em>1</em>

<em>(</em><em>iii</em><em>)</em><em>2</em><em>0</em><em>=</em><em>3</em><em>(</em><em>3</em><em>)</em><em>+</em><em>1</em><em>1</em>

<em>(</em><em>iv</em><em>)</em><em>2</em><em>3</em><em>=</em><em>3</em><em>(</em><em>4</em><em>)</em><em>+</em><em>1</em><em>1</em>

<em>it</em><em> </em><em>does</em><em> </em><em>make</em><em> </em><em>sense</em><em>.</em><em>.</em><em>.</em><em>.</em>

Write a quadratic function, in standard form, that fits the set of points. Solve it as a system of three equations. (-4, 9), (0,

Tresset [83]

Answer:

$\boxed{y=2x^2+4x-7}$

Step-by-step explanation:

Let the quadratic function be

$y=ax^2+bx+c$

We substitute $(-4,9)$ into the equation to obtain;

$9=a(-4)^2+b(-4)+c$

$\Rightarrow 9=16a-4b+c---(1)$

We substitute $(0,-7)$ to obtain;

$-7=a(0)^2+b(0)^2+c$

$\Rightarrow c=-7---(2)$

We finally substitute $(1,-1)$ to obtain;

$-1=a(1)^2+b(1)^2+c$

$\Rightarrow -1=a+b+c---(3)$

We put equation (2) into equation (1) to get;

$9=16a-4b-7$

$16a-4b=16$

$\Rightarrow 4a-b=4---(4)$

$\Rightarrow -1=a+b-7$

$\Rightarrow a+b=6---(5)$

We add equation (4) and (5) to get;

$4a+a=6+4$

$\Rightarrow 5a=10$

$\Rightarrow a=2$

We put $a=2$ into equation (5) to get;

$2+b=6$

$\Rightarrow b=6-2$

$\Rightarrow b=4$

The reqiured quadratic function is

$y=2x^2+4x-7$

Someone help me with this please

anzhelika [568]

for question 1

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Height = 15 cm

Using the formula

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

Area of base = 7× 5/2= 17.5 cm²

Perimeter of base = (7+7+7) = 21 cm

Surface area = 2B + Ph

Surface area of prism = 2×17.5+ 21×10 = 245cm²

Volume = Bh = 17.5×10 = 175 cm³

Mrs. Simpson is frosting circular sugar cookies. Each cookie is 7 cm in diameter. How many square inches will she need to frost

Alexus [3.1K]

Answer:

51.92 square inches

Step-by-step explanation:

Area of a circle = (pi)(r^2)

if the diameter is 7, the radius is 3.5

A = 3.14 x 3.5

A = 10.99 cm^2 for one cookie

10.99 x 12 for a dozen = 131.88 cm^2

converting cm to inches, you divide by 2.54

131.88/2.54 = 51.92 square inches.
