Find the measure of angle ABD.

Answer:

b

Step-by-step explanation:

f(x) = -9x² + 2x + 2

Discriminant = 2² - 4(-9)(2) = 76

The discriminant is positive, so there are two distinct roots.

Answer:

Step-by-step explanation:

(19 - 7)/(6 - 2) = 12/4= 3

y - 7 = 3(x - 2)

y - 7 = 3x - 6

y = 3x + 1

Answer:

Step-by-step explanation:

Jupiter lighthouse , r=18 miles, A= 2*3.14*r^2

A Jupiter=2*3.14*18*18=2034.72 mi^2

Hillsborough light house, r= 28 miles,

A Hillsb=2*3.14*28*28=4923.52 mi^2

the difference is

4923.52-2034.72=2,888.80

The logarithmic expressions are log6 with base 3 and log5 with base 4.

What is logarithmic function?

It is the inverse of the exponential functions. It is equal to y=㏒x.

A) log 8 with base 3=log8/log3=0.903089987/0.4771212547=1.8927

B) log 6 with base 3=log6/log3= 0.77815125038/0.4771212547=1.6309

C) log 5 with base 4=log5/log4=0.69897000433/0.60205999132=1.1609

D) log 32 with base 2=log32/log2=1.50514997832/0.30102999566=5

E) log 7 with base 4=log 7/ log 4=

Step-by-step explanation:

Answer:

Your answer is A

Step-by-step explanation:

The graph of y = f(x) will shift left 2 units.

The equation that is equivalent to x + 8 = 21 is (x + 8) × 4 = 21 × 4

Given the equation

To get a similar expression we will either subtract, multiply, divide or add the same constant to both sides of the equation

Multiplying both sides by 4 will give:

Hnce the equation that is equivalent to x + 8 = 21 is (x + 8) × 4 = 21 × 4

Answer:

A) -4

Step-by-step explanation:

There are two ways of solving this:

1.) Plugging in the answer choices

Since the equation needs to be equal to or less than 1 (this is due to the less than or equal to sign:  ≤)

You will then set the equation: -2x-6 ≤ 1

You will then take each answer choice and plug it into the original equation.

Plug in -4:  -2(-4)-6 ≤ 1   this will result in 2 ≤ 1

Plug in -3:   -2(-3)-6 ≤ 1 this will result in 0 ≤ 1

Plug in -2:   -2(-2)-6 ≤ 1 this will result in -2 ≤ 1

Plug in -1:     -2(-1)-6 ≤ 1 this will result in -4≤ 1

The only one that is not true is when you plug in x=-4 into the equation -2x-6.  This results in the equation being equal to 2.  2 is not less than 1, making the equation false.

Method 2: Solving the inequality

You can essentially solve for x like a normal inequality.

Instead of solving for -2x-6 = 1, we are doing -2x-6 ≤ 1.

First: Add 6 to the right side

-2x ≤ 1+6 --->>>>  2x ≤ 7

Second:  Divid both sides by -2

***Note: When you divivde by a negative when solving an inequality, you must switch the sign. ***

x ≥ -3.5   (hence the sign swtiches from ≤ to ≥ since we divided by a negative value in the equation)

x ≥ -3.5 states that any number greater or equal to -3.5 will work.  -4 is less than -3.5, thus it will not satisfy the inequality.
