Plz do the last box’s for me

Given:

An exponential equation passes through the points (0,4) and (2,9).

To find:

Exponential equation that passes through the given points.

Solution:

Let the required exponential function is:

[tex]y=ab^x[/tex]           ...(i)

The function passes through the points (0,4) and (2,9). It means the above equation must be true for these points.

[tex]4=ab^0[/tex]

[tex]4=a(1)[/tex]

[tex]4=a[/tex]

And,

[tex]9=ab^2[/tex]

Substituting [tex]a=4[/tex], we get

[tex]9=(4)b^2[/tex]

[tex]\dfrac{9}{4}=b^2[/tex]

[tex]\pm \sqrt{\dfrac{9}{4}}=b[/tex]

[tex]\pm \dfrac{3}{2}=b[/tex]

In an exponential function b>0. So, [tex]b=\dfrac{3}{2}[/tex].

Putting [tex]a=4,b=\dfrac{3}{2}[/tex] in (i), we get

[tex]y=4\left(\dfrac{3}{2}\right)^x[/tex]

Therefore, the required exponential function is [tex]y=4\left(\dfrac{3}{2}\right)^x[/tex].

Answer:

B. 40°

Step-by-step explanation:

AB // ED       ∠ABC = ∠EDF = 50°

Answer: I think the perimeter is 17ab4

Step-by-step explanation:

Interpreting as: circle 8.5 inches.

Assuming

"circle"

is a geometric object

circle | radius 8.5 inches

Equation:

(x - x_0)^2 + (y - y_0)^2 = 72.

(assuming center (x_0, y_0))

Properties:

diameter | 17 inches

area enclosed | 227 in^2 (square inches)

circumference | 53.4 inches

answer is D. 17/C

Answer:

Isosceles and Right

Step-by-step explanation:

An Isosceles Right Triangle is a right triangle that consists of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent. Thus, in an isosceles right triangle, two legs and the two acute angles are congruent.

Answer:

Isosceles and right

Step-by-step explanation:

We have a picture of triangle and are asked to name it, look at definitions below :

Isosceles - Geometrical figure with three sides and three angles

Right - Triangle where one angle is a right angle (90°)

Scalene - Triangle where all three sides have different lengths

Acute - Triangle where all three sides are less than 90°

If we look at the triangle, we can tell that it has three sides and three angles, therefore isosceles must be in one of the answer choices. Crossing out the options scalene and acute / scalene and right.

Now we have two options and we need to determine whether this triangle is an acute triangle or is a right triangle.

To figure out so we can look at the angle in the bottom left, which when measures equals to 90°. Therefore making it a right triangle and crossing out the other option.

Our answer left is Isosceles and Right.

Answer:

x=3, y= -6

Step-by-step explanation:

make 4+y= -x as equation (1) and make y=2x-10 as equation (2, then you must find a third equation either from equation (1)or (2). If you choose to find equation (3) from (2) it will be y=2x-10 , then substitute equation (3) from (1) because you can't choose (2) , then it will be 4+(2x-10)= -x

the answer will be x =2

substitute x from equation (3)

y=2x-10

y=2 (2)-10

y= -6

Answer:

3,672

Step-by-step explanation:

Given the sequence 6, 9, 12...

The sequence is an arithmetic sequence

first term a = 6

common difference d = 9 - 6 = 12 - 9 = 3

number of terms n = 48

Sn = n/2[2a+(n-1)d]

Substitute the given values

S48 = 48/2[2(6)+(48-1)(3)]

S48 = 24(12+(3*47))

S48 = 24(12+141)

S48 = 24(153)

S48 = 3,672

Hence the sum of the first 48terms is 3,672

Answer:

A) [tex]\frac{1}{2}(9+15)w[/tex]

Step-by-step explanation:

Area of a trapezoid is [tex]\frac{1}{2}(base1+base2) *h[/tex]

[tex]A=\frac{1}{2}(9+15)*w[/tex]

Mass = density x volume

Mass = 178 x 25 = 4,450 grams

Answer:

Area of the unshaded sector = 113.4 sq units

Area of the shaded sector = 200.6 sq units

Step-by-step explanation:

First let us calculate the area of the circle

Area of the circle = πr²

radius r  = 10units

Area of the circle = π(10)²

Area of the circle = π(100)

Area of the circle = 3.14(100)

Area of the circle = 314 sq. units

Area of a sector = theta/360 * πr²

Area of the unshaded sector = 130/360 * 314

Area of the unshaded sector = 13/36 * 314

Area of the unshaded sector = 113.389 sq units

Area of the unshaded sector = 113.4 sq units

Area of the shaded sector = Area of circle - Area of the unshaded sector

Area of the shaded sector = 314 - 113.89

Area of the shaded sector = 200.6sq. units

Answer:

Lucas monthly net pay is $1758

Step-by-step explanation:

Lucas works for a salary of $2,396 per month.

His deductions include $360 of federal income tax,

$148 for Social Security,

$35 for Medicare, and

a $95 insurance premium.

Now,

2396 - 360 - 148 - 35 - 95 = 1758

Thus, Lucas monthly net pay is $1758

Answer:

(x+2)(x-8)

Step-by-step explanation:

Answer: D.

Step-by-step explanation:

The way to know if it is “greater than or equal to” opposed to jsut greater than is to look at the dot. If it is filled in it is “equal to” if not it isn’t.

the correct answer is B 70

35 + 75 = 110

triangles always make up 180°

180 - 110 = 70

Answer:

23.13m^2

Step-by-step explanation:

We'll use 3.14 for pi as instructed.

We can rearrange the figure to one square and 2 full circles.

Area of the square is 3m*3m = 9m^2

Area of a single full circle is pi*1.5m*1.5m = pi*2.25m^2 = 3.14*2.25m^2 = 7.065m^2

Full area = 9m^2 + 2*7.065m^2 = 9m^2 + 14.13m^2 = 23.13m^2

Answer:

23.14

Step-by-step explanation:

Answer:

because the length is 4 feet more than the width

=> the length is x + 4 (feet)

because the base has an area of 21 square feet

=> x(x + 4) = 21

<=> x² + 4x = 21
