Answer:

g(4) = 157

Step-by-step explanation:

g(x) = 8x^2 + 9x - 7

Let x  =4

g(4) = 8 * 4^2 +9*4 -7

       =8*16 +36 - 7

        =128+36-7

        =157

Answer:

157

Step-by-step explanation:

g(x)=

[tex]{8x}^{2} + 9x - 7[/tex]

g(4) =

[tex]8( {4})^{2} + 9(4) - 7 \\g(4) = 8 \times 16 + 36 - 7 \\ g(4) = 128 + 29 \\ g(4) = 157[/tex]

Answer:

3/4

Step-by-step explanation:

The given equation is in the form of y=mx+b

This is where m is the slope, and b is the y intercept.

This said, the slope of the equation is 3/4.

I will attach an image of the graph. I put the equation in a graphing calculator.

If you need to graph by hand, first plot the y intercept, (0,2) and then use the slope to find more points. Then, connenct the points with a ruler.

The image you attached is not the graph of y=3/4x+2, it is the graph of y=5.

It's slope is equal to 0.

Answer:

The answer should be A)3

Answer:

  3 or 4, depending on the intended meaning of [x]

Step-by-step explanation:

Perhaps you mean ...

  [tex]\displaystyle f(x)= \lfloor x\rfloor -5\\\\f(8.6)=\lfloor 8.6\rfloor-5=8-5=3[/tex]

__

On the other hand, perhaps you mean ...

  [tex]\displaystyle f(x)=\lceil x\rceil -5\\\\f(8.6)=\lceil 8.6\rceil-5=9-5=4[/tex]

Answer:

F(y^2) = 1/ (y^2-3)

Step-by-step explanation:

F(x) = 1/ (x-3)

Replace x with y^2

F(y^2) = 1/ (y^2-3)

Answer: f(y^2) = 1/((1/(x-3))^2-3)

Step-by-step explanation:

To start to understand this equation realize y = f(x) but f(x) gives a little bit more information specifically to define x as whatever is in the parenthesis of f(_).

For example f(x) = x/2

so lets say x = 2

so "f(2) = 2/2" or "y = 1 when x = 2"

In this equation y or f(x) = 1/(x-3)

so to get f(y^2) = 1/(x-3)

square the value of y and plug it into 1/(x-3) as the value of x

f(y^2) = 1/(y^2-3)

CD

Step-by-step explanation:

Apex

The name of the savings account that offers higher interest rates, but in which a person's money must stay deposited for a specific amount of time is B. CD.

Money market account, Certificates of deposits (CD) and the regular savings account are all different types of savings account.

Regular savings account has only lower interest rate while both CD and Money market account have higher interest rates.

And the money must be stayed in the account for a fixed period of time in CD accounts. This is not required in the money market accounts.

Thus, CD is the correct answer.

Answer:

Interest earned is $8.75

Total amount of money earned = 708.75

Step-by-step explanation:

Principal = 700

Rate =  2.5%

Time = 6 months = 6/12 years = 0.5 years

Interest = PTR/100

= 700x0.5x2.5/100

= 8.75

Total amount = P + I

= 700 + 8.75

= 708.75

Answer: 460 Workers

Step-by-step explanation: This is pretty simple, we know there's 198 men...and the ratio is 3:4.

198 ÷ 3 = 66

66 * 4 = 264

There are 264 female workers, and 196 male workers...

264 + 198 = 460

In total, there are 460 workers.

Answer:

On the second step there is a mistake. You have to multiply 2 times 2 before you add the five

Answer:

See below;

Step-by-step explanation:

We are given the following;

5 + [ 2 * 2 + 5 ], ⇒ add 2 and 5

5 + [ 2 *  7 ], ⇒ multiply 2 by 7

5 + 14, ⇒ combine like terms

Solution; 19

Now as we can see from the first ⇒ second step the process as to simplify the expression 5 + [ 2 * 2 + 5 ] further, was by adding 2 and 5. Of course by PEDMAS, it would be that multiplication takes place before that of addition, so that it should have been that 2 was multiplied by 2 first!

Solution below;

Steps |                            |

          |  5 + [ 2 * 2 + 5 ]  |

Answer: 3m+2=-10 does not have the same solution as the rest of the equations

Step-by-step explanation:

3m+2=-10 (m= -4)

2-3m=-10 (m=4)

-10=-3m+2 (m=4)

-3m+2=-10 (m=4)

-3m+2=-10 (m=4)

Answer:

140

Step-by-step explanation:

Angle 4 is congruent to angle 2 by corresponding angles postulate.  Therefore, angle 2 is also 40.  Angle 2 and angle 3 are supplementary, or add up to 180 because they are on a straight line.  140 and 40 add up to 180 so angle 3=140 degrees

Answer: 3 seconds

Step-by-step explanation:

Hi, the correct equation is d (t) = 144- 16 t²

So, to answer this question we have to analyze the information given:

When the car reaches the ground the distance, d (t) of the car from the ground is 0.

0 = 144- 16 t²

Solving for t:

16 t² =144

t²=144/16

t²= 9

t = √9

t = 3 seconds

Answer: The height of the model on the right is 22.5 cm .

Step-by-step explanation:

We can see that , the given different models of the same triangular-shaped garden are similar.

For the first model 1 cm = 3.75 m

whereas for the second model 1 cm = 2.5 m

Now , the constant rate of proportion for this (k) = [tex]\dfrac{3.75}{2.5}=\dfrac{375}{250}=1.5[/tex]

Now , if height of the model on the left is 15 cm , then the height of the model on right = 15 x k

= 15 x 1.5

= 22.5 cm

Hence, the height of the model on the right is 22.5 cm .

Answer:

sin(theta)=3/5

Step-by-step explanation:

tan(theta)=3/4

sec^2(theta)=1+tan^2(theta)=1+(3/4)^2=1+9/16=(16+9)/16=25/16

sec(theta)=square root of(25/16)=5/4

sec(theta)=1/cos(theta)=5/4

cos(theta)=4/5

sin^2(theta)=1-cos^2(theta)=1–16/25=(25–16)/25=9/25

sin(theta)=3/5

So

sec(theta)=5/4

sin(theta)=3/5

Answer:

1 hour

Step-by-step explanation:

Let's assume that Patrick is travelling on a straight line throughout the whole path in order to minimize the distance.

The number of miles that he can travel on a full tank is:

[tex]m = 5\ mpg*4\ gallons\\m=20\ miles[/tex]

The distance travelled by Patrick in one hour (from 2p.m. to 3p.m.) is:

[tex]d^2=6^2+8^2\\d=\sqrt{100}\\ d=10\ miles[/tex]

If he is travelling at 10 miles per hour, and he could travel for a total of 20 miles, then the time remaining before the tank runs out of gasoline is:

[tex]t=\frac{20-10}{10}\\ t=1\ h[/tex]

If he continues at this rate, the gas will last for 1 more hour.

Answer:

She made 40% of her shots.

Step-by-step explanation:

First, you would subtract 10 - 6 = 4.

Second, you would make 4/10 a decimal to convert it to a percent by moving the decimal point to places to the right = .40 = 40%.

Your answer is 40% of her shots were made.

Beth made 40 percentage of  shots.

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

The total number of shots taken by Beth = 10

The missed shots by Beth= 6

The Shots which are made by Beth = 10-6 =4

The percentage of shots that Beth make,

= 4/10×100

=40%

40% shots Beth made during contest.
