Answer:

[tex]f(x)=-7(x-3)^2+1[/tex]

Step-by-step explanation:

Vertex form of a quadratic is given by:

[tex]f(x)=a(x-h)^2+k[/tex]

Where (h, k) is the vertex and a is the leading coefficient.

We are given that the vertex is (3, 1). Hence, h = 3 and k = 1. By substitution:

[tex]f(x)=a(x-3)^2+1[/tex]

We are also given a point (2, -6). This means that when x = 2, f(x) = -6. Hence:

[tex]-6=a((2)-3)^2+1[/tex]

Solve for a. Subtract:

[tex]-6=a(-1)^2+1[/tex]

Simplify:

[tex]-6=a+1[/tex]

Therefore:

[tex]a=-7[/tex]

Hence, our quadratic is:

[tex]f(x) = -7 (x-3)^2 + 1[/tex]

Answer: ∠B = 82°

Step-by-step explanation:

To find the measure of B, you have to find the measure of A.

m∠143° + m∠A = 180° because they are a linear pair

m∠A + 143 = 180

Subtract both sides by 143

m∠A = 37

Since you know the measure of angle A, you can find angle B

Angle A, B, and C should add up to 180° as triangles' angles sum up to 180°.

∠B + ∠A + ∠C = 180°

Substitute

∠B + 37 + 61 = 180

∠B + 98 = 180

Subtract 98 from both sides

∠B = 82°

Given:  1) weight of Dylan= 45 pounds

            2) weight of Alan= 3 pounds more than twice the weight of Dylan

            3)weight of Bruce = 12 pounds less than three times the weight of

                                               Dylan.

To Find: How much more does Bruce weighs than Alan .

Solution:

weight of Dylan= 45 pounds

weight of Alan= 3 pounds more than twice the weight of Dylan

                        = 3 + ( 2×45)  pounds

                        = (3+ 90) pounds

                        = 93 pounds  

weight of Bruce= 12 pounds less than three times the weight of Dylan

                          = (3× 45) - 12  pounds

                          = (135) - 12 pounds

                          = 123 pounds

therefore, the amount by which Bruce weighs more than Alan will be given by:

weight of Bruce - weight of Alan

= 123 pounds - 93 pounds

= 30 pounds

Hence, Bruce weighs 30 pounds more than Alan.

Answer:

the answer is c because of what the text says

Answer:

5

Step-by-step explanation:

The left side is equal to:

x/(2.52-2.02) = x/0.5 = 2x

Let's simplify the numerator of the right side.

9*(31/20 - 1.05) = 9*(0.5) = 9/2

The denominator is 43/40 - 35/8 /7 = 43/40 - 5/8 = 43/40 - 25/40 = 18/40 = 9/20.

So 2x = (9/2)/(9/20) = 10

x = 5

Answer:

x=-2835/62 or (in decimal form) 45.726

See below

All the inequalities can be solved by making a table, but once they are simple factored quadratic expressions, we already know what interval it will have.

Step-by-step explanation:

1)

[tex]x^2+9x+14>0[/tex]

Factoring the expression, we have

[tex](x+2)(x+7)>0[/tex]

Considering that

[tex](x+2)(x+7)=0[/tex]

for [tex]x = -2[/tex] and [tex]x=-7[/tex] you can see that for

[tex](x+2)(x+7)>0[/tex]

[tex]x \not\in (-7, -2)[/tex]

Therefore,

[tex]S = \{x\in\mathbb{R} : x<-7 \text{ or } x>-2 \}[/tex]

[tex]S = (-\infty,-7)\cup (-2,\infty)[/tex]

2)

[tex]x^2-10x+16<0[/tex]

You can factor it again.

[tex](x-2)(x-8)<0[/tex]

You can make the table to solve all the inequalities, but once we have the expression [tex]< 0[/tex], we know that

[tex]2<x<8[/tex], therefore,

[tex]S = (2, 8)[/tex]

3)

[tex]2x^2+11x+12<0[/tex]

Factoring we have

[tex](2x+3)(x+4)<0[/tex]

Find the solutions for

[tex](2x+3)(x+4)=0[/tex]

And we know that

[tex]-4<x<-\dfrac{3}{2}[/tex]

[tex]S = \left(-4,-\dfrac{3}{2}\right)[/tex]

Step-by-step explanation:

Convert metre to centimetre

Recall: 1m = 100cm

That means,

3m = 3 * 100cm = 300cm

Now we compare them since they have the same unit.

300cm : 6cm

50 : 1

Answer = 50 : 1

Answer:

C-$6.00 monthly fee and $1.25 per video game

Step-by-step explanation:

The monthly fee and the cost per video game that Susan pays

use the rental service is C. $6.00 monthly fee and $1.25 per video game.

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.

From the graph the two pair of points are (0, 6) and (8, 16).

So, slope(m) = (16 - 6)/(8 - 0).

slope(m) = 10/8.

slope(m) = 5/4.

slope(m) = 1.25.

So, The monthly subscription fee is $1.25.

Now, Cost of one video game can be obtained by equation y = mx + b.

6 = 1.25(0) + b.

b = 6, so the cost of per video game is $6.

Answer:

[tex]\frac{1}{5}[/tex]

Step-by-step explanation:

To find the scale factor of a dilation, we first find two corresponding sides. For example, the top edge of the black shape corresponds with the top edge of the purple shape. The top edge of the black shape measures 15 units while the top edge of the purple shape measures 3 units

Now, we divide the length taken from the figure by the length taken from the original shape. In this case, we divide the length of 3 by the length of 15.

Answer:

174 people preferred drinking water.

Step-by-step explanation:

Given that:

A total of 450 males and females were surveyed.

203 were males.

Number of females = 450 - 203 = 247 females

247 females were surveyed.

Now, we will find the number of females who prefer water.

Let,

x be that number.

Total number of females = Soda + Iced tea + Lemonade + Water

247 = 28 + 44 + 67 + x

247 = 139 + x

247-139 = x

x = 108

Number of people who prefer water = 108 + 66 = 174

Hence,

174 people preferred drinking water.
