Step-by-step explanation:

15(5+2) is the Answer

The greatest common factor to rewrite 75+30 as 15(5+2)

Greatest common divisor (GCD) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

An expression is a combination of numbers, variables and operators.

The given expression is 75+30.

By using distributive law we can find this.

Let us find factors of 75 and 30.

The factors of 75 are 1, 3, 5, 15, 25, 75

The factors of 30 are 1, 3, 5, 9, 15, 45

Their GCF is 15.

To get 75, we will multiply 15 by 5.

To get 30, we will multiply 15 by 2.

By using distributive property

75+30 can be splitted to factors as

15(5+2)

Hence  the greatest common factor to rewrite 75+30 as 15(5+2)

Answer:

84

Step-by-step explanation:

(92 + 96 + 88 + x) ÷ 4 = 90

92 + 96 + 88 + x/4 = 90

276 + x/4 = 90

(276 + x) × 4/4 = 90 × 4

276 + x = 360

x = 360 - 276

x = 84

The reasonable estimate of the current customer price index is 195. The option B is the correct option.

Customer price index is the price index which measures the weight average of price of basket of customers goods or services.

It can be given as,

[tex]\rm CPI_t=\dfrac{C_t}{C_0}\times 100[/tex]

Here [tex]\rm C_t[/tex] is the cost of market basket in current period and [tex]\rm C_0[/tex] is the cost of market basket in the base period.

Cost of market basket in current period is

[tex]\rm C_t=15.66+119.75+23.99+37.50\\\\C_t=196.9[/tex]

Cost of market basket in 1983 is,

[tex]\rm C_0=8.85+71.25+13.95+22.7\\\\C_0=116.8[/tex]

Substitute all the values in the formula

[tex]\rm CPI_t=\dfrac{C_t}{C_0}\times 100\\\\\rm CPI_t=\dfrac{196.9}{116.8}\times 100\\\\\rm CPI_t=1.685\times 100 \\\\ CPI_t=168.5\\\\\rm CPI_t= 170 \ \rm approx[/tex]

Thus the value of current CPI is 168.5 which is near about the 170.

Hence, the reasonable estimate of the current customer price index is 195. The option B is the correct option.

Find the answer with the theorems related to isosceles triangle and the exterior angle theorem

The time taken for the golf ball to reach the ground is 1 s.

The path of motion of the golf ball can be described as parabolic because it is projectile.

When the golf ball reaches the ground, the final velocity will be zero.

Velocity of the golf ball is change in height with time.

v = dh/dt

h(t) = -16t² + 32t  + 128

dh/dt = -32t + 32

0 = -32t + 32

32t = 32

t = 1 s

Thus, the time taken for the golf ball to reach the ground is 1 s.

Answer:

x = 2, -2

explanation:

[tex]\sf y=x^4+3x^3+x^2-12x-20[/tex]

Find a factor for this equation:

-5 < x < 5

-------------

f(-3) = 25

f(-2) = 0

f(-1) = -9

f(0) = -20

f(1) = -27

f(2) = 0

f(3) = 115

Hence found that ( x -2) and ( x + 2) are the factor of the following equation.

Divide both by the following equation:

[tex]\sf \rightarrow \dfrac{x^4+3x^3+x^2-12x-20}{\left(x-2\right)\left(x+2\right)}[/tex]

[tex]\sf \rightarrow \dfrac{\left(x-2\right)\left(x+2\right)\left(x^2+3x+5\right)}{\left(x-2\right)\left(x+2\right)}[/tex]

[tex]\sf \rightarrow x^2+3x+5[/tex]

Using quadratic formula: [tex]\sf x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a} \ \ when \ \ ax^2 + bx + c = 0[/tex]

[tex]\sf \hookrightarrow x_{1,\:2}=\dfrac{-3\pm \sqrt{3^2-4\cdot \:1\cdot \:5}}{2\cdot \:1}[/tex]

[tex]\hookrightarrow x=-\dfrac{3}{2}+i\dfrac{\sqrt{11}}{2},\:x=-\dfrac{3}{2}-i\dfrac{\sqrt{11}}{2}[/tex]

Thus the zero's of the function are:

x = 2, -2

Answer:

[tex]x=2, x=-2[/tex]; [tex]\frac{-3\pm i\sqrt{11}}{2} \in \mathbb{C}[/tex]

Step-by-step explanation:

Zeroes are found by setting the RHS = 0.

Since the quantity [tex]x^4+3x^3+x^2-12x-20[/tex] is a 4th degree polynomial there isn't a formula that gives us the solution, so we're stuck having to divide: to do so we make THE LIST: you list the divisors of the constant term without its sign (20: 1,2,4,5,10,20), the divisor of the lead coefficient (1), and you divide the first by the second in any possible way, adding a plus or minus:

[tex]\pm1, \pm2, \pm4, \pm5,\pm10,\pm20[/tex]. At this point you just have to check, replacing each one in the equation until you find two values that work (why two? You need to lower the degree of the polynomial by two, if you found only one you'd be stuck with a third degree equation which doesn't have an "easy" solving formula).

After some adding and multiplying you find that both 2 and -2 make the expression to zero. At this point you have two options

First is to divide the given expression by[tex](x-2)(x-2)=(x^2-4)[/tex] or, as I did in the image, notice that you will end up with a 2nd degree polynomial, whose coefficient you find by multiplying and confronting with the original equation.

Either way, you will end up with

[tex](x+2)(x-2)(x^2+3x+5)=0[/tex]

First two factors will give [tex]x=-2; x=2[/tex] respectively, while the third term has no real solutions (it still offers a pair of solutions in [tex]\mathbb{C}[/tex] which I'll add for the sake of completeness, but you're most likely required to look for real solutions only).

Answer:

So a line perpendicular to this equation would be any line with a slope of -3/4 (the negative reciprocal of the slope)

Step-by-step explanation:

First convert the original equation into y = form to find the slope.

Subtract 4x on both sides leaving -3y = -27 - 4x

This leaves y = (-27 - 4x)/(-3)

You can divide both -27 and -4x by -3 individually to get 9 and 4/3 respectively

This makes your equation y = 9 + (4/3)x

Whenever an equation is in y = mx + b form, the 'm' represents the slope. In this case the slope is 4/3.
