Answer: D

<u>Step-by-step explanation:</u>

NOTES:

  • x-intercept is when y = 0
  • y-intercept is when x = 0

          <u>f(x)</u>        <u>g(x)</u>

x-int:     1          -1

y-int:    -1           1


A) x-intercepts are not equal so FALSE

B) y-intercepts are not equal so FALSE

C) y-intercept of f(x) is not greater than g(x) so FALSE

D) x-intercept of f(x) is greater than g(x) so TRUE

Answer: Choice D) x intercept of f(x) is larger then the x intercept of g(x)

===================================

Explanation:

A) False. The x intercept of f is 1 while the x intercept of g is -1. The x intercept happens when y = 0. Visually, this is where the graph crosses the x axis.

B) False. The y intercept of f(x) is -1, compared to the y intercept of g(x) is +1. The y intercept happens when x = 0, which is when the graph crosses the y axis.

C) False. The y intercept of f(x) is actually smaller than the y intercept for g(x)

D) True. The x intercept of f(x) is larger than the x intercept of g(x). Compare 1 and -1, which are the x intercepts for f and g in that order.

Which side lengths form a right triangle 4, 8, 12
Lostsunrise [7]
(4^2+8^2)^.5 = 8.944
It's not 12.
So 4,8,12 can't be the side lengths of a right triangle.

Joan has earned grades of 88, 94, 92, and 98 on math tests so far. What must her next grade be to give her an average grade of 6
Ira Lisetskai [31]

Answer:

see the explanation

Step-by-step explanation:

Let

x ------> the next grade

we know that

To find the average grade sum the grades by the number of math test

so

60=\frac{(88+94+92+98+x)}{5}

solve for x

Combine liker terms in the right side  

60=\frac{(372+x)}{5}

Multiply by 5 both sides

300=372+x

Subtract 372 both sides

300=372+x

x=-72 -----> this is not make sense

The grade cannot be a negative number

so

For x=0

The minimum average grade is

\frac{(372)}{5}=74.4

Solve for all three unknowns
Rina8888 [55]

Answer:

x= 32.3 (3 s.f.)

θ= 21.8° (1 d.p.)

α= 68.2° (1 d.p.)

Step-by-step explanation:

Applying Pythagoras' Theorem,

x²= 12² +30²

x²= 144 +900

x²= 1044

Square root both sides:

x =  \sqrt{1044}

x= 32.3 (3s.f.)

\boxed{ \tanθ =  \frac{opp}{adj}  }

\tanθ =  \frac{12}{30}

θ = \tan^{ - 1} ( \frac{12}{30} )

θ= 21.801° (3 d.p.)

θ= 21.8° (1 d.p.)

\tan\alpha  =  \frac{30}{12}

\alpha  =  \tan ^{ - 1} ( \frac{30}{12} )

\alpha= 68.2° (1 d.p.)

Alternatively,

α +θ +90°= 180° (∠ sum of triangle)

α +21.801° +90°= 180°

α +111.801°= 180°

α= 180° -111.801°

α= 68.199°

α= 68.2° (1 d.p.)

Can u help me with this question
Troyanec [42]

Answer:

14

Step-by-step explanation:

The question is asking for the value of A when n = 2

So we just need to plug in 2 for n

A(2) = 10 + (<em>2</em>-1)(4) = 10 + (1)(4) = 10 +4 = 14
