1. y= -x squared -7x-12
2. y= 3x squared +11x+10

Answers

Answer 1

Answer:

1) x-intercepts are at -3 and -4

2) x-intercepts are at 5/3 and 2

Step-by-step explanation:

1) y = -x^2 - 7x - 12  is -(x + 3) (x + 4)

2) y = 3x^2 + 11x + 10  is (3x + 5) (x + 2)

What is the area of the circle ?

Answers

Answer:

113.04 [tex]m^{2}[/tex]

Step-by-step explanation:

Area of a circle is π x [tex]r^{2}[/tex].

I'm assuming that you're using 3.14 as π.

Since the radius of the circle is 6 m, all you need to do is plug it in!

Area = 3.14 × [tex](6)^{2}[/tex]

Area = 3.14 × 36

Area = 113.04 [tex]m^{2}[/tex], which is the third answer choice.

I think it is 113.04

Answers

Answer:

$97.2

Step-by-step explanation:=Given

The expression p + 0.08p

where P= the initial price

let y be the total cost, so that

y=p + 0.08p

for p=$90

y=90+0.08*90

y=90+7.2

y=$97.2

Hence the total cost for a $90 price is $97.2

6x - 5x = 14

m∠A = m∠C = 140° ÷ 2 = 70°

Doug has two German Shepherds. The
larger dog weighs 70 1/2 pounds. If the
smaller dog weighs 75% as much as the
larger dog, find the smaller dog's weight.
wait ugh i asked the wrong question help pls and thank you

Answers

Answer:

52 7/8 pounds

Step-by-step explanation:

Find the smaller dog's weight by multiplying the larger dog's weight by 0.75:

70.5(0.75)

= 52.875 or 52 7/8 pounds

So, the smaller dog weighs 52 7/8 pounds

The required weight of the smaller dog is 52.875 pounds.

Given that,
Doug has two German Shepherds. The larger dog weighs 70 1/2 pounds. If the smaller dog weighs 75% as much as the larger dog, To find the smaller dog's weight.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements.

What is percentages?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Let the weight of the smaller dog be x,
The weight of the smaller dog is 75% of the larger dog
x = 75% of 70 1/2
x = 0.75 * 70.5
x = 52.875

Thus, the required weight of the smaller dog is 52.875 pounds.

PLEASE HELP ASAP I WILL AWARD BRAINLIEST

Answers

Answer:

None of the Above

Step-by-step explanation:

Key Skills required are: One Variable Equations, Supplementary Angle Pairs, Substitution, and Triangles.

1) To find the measure of Angle C, we first need to find the measure of angle DBC and Angle D.

2) We are given that Angle EBA is x and Angle EBD is 4x+13 and Angle D is 3x + 9 (we will use Angle D later in the problem)

3) Now, we need to use the fact that Angle EBA and Angle EBD are supplementary (they form a linear pair, so they are supplementary).

A pair of supplementary angles add up to  180 degrees (as they form a straight angle).

4) x + 4x + 13 = 180

5) Combine like terms --> 5x + 13 = 180

6) Move 13 to the other side --> 5x = 167

7) Divide by 5 and solve for x: x= 33.4

8) Now we got that x is 33.4, we can get the measure of angle DBC and Angle D.

9) Angle DBC is congruent to Angle EBA. So to find the measure of DBC we need to find the measure of Angle EBA. EBA is just x, so it is 33.4 degrees

10) Therefore, Angle DBC also measures 33.4 degrees.

11) To find angle D, we substitute x into 3x + 9 (We are given angle D is 3x + 9 based on the problem)

12) 3(33.4) + 9 = 100.2 + 9 = 109.2

13) Now we use the interior angles sum of a triangle to find Angle C.

The interior angles of a triangle sum up to 180 degrees.

14) With the statement above we can make this equation: 109.2 + 33.4 + Angle C = 180

15) Simplify by combining like terms: 142.6 + Angle C = 180

16) 37.4 degrees would be the measure of C, so I feel it would be none of the above.

Hope you understood and have a nice day!! :D
